Bronchial asthma (BA) is a global problem. The incidence of bronchial asthma is growing all over the world. It is among the top ten noncommunicable chronic diseases, which are the main cause of death among people, reducing life expectancy by 6.6 years for men and 13.5 years for women.
MIGRATION OF HEAVY METALS IN THE AGRICULTURAL SOIL PROFILE AROUND THE GANJAKAZAKH ZONE OF THE REPUBLIC OF AZERBAIJAN
Authors: Maharramova Sevinj Telman gizi
Published: February 2022

Depending on the nature and characteristics of the heavy metals that accumulate on the surface of the soil, separated from vehicle waste around the highway, they migrate downwards in the soil profile. The course of this process and the properties of heavy metals have been studied by many researchers. The migration of heavy metals in the soil profile later leads to the contamination of plants, especially agricultural crops, with toxic substances. It enters the food chain around the highway, especially with the more intensive accumulation of lead. It is considered dangerous for animals when the amount of lead in dry fodder plants is 100 mg/kg. Its amount migrates deep into the soil profile for several years and remains in the soil for many years without losing its effect. Until recent years, tetraethyl lead was added to all fuels to increase its combustibility and increase the deformation pressure, which caused the release of 200 400 mg of lead into the atmosphere during the combustion of one liter of gasoline. The study found that the migration of heavy metals in the soil profile depends on its granulometric composition, density, thickness of many organic compounds and pH
Study of the efficiency of trapped gas displacement by non-hydrocarbon gases from water-flooded gas condensate reservoirs
Authors: Matkivskyi S. V.
Published: February 2022

Analyzing industrial data and the results of theoretical studies, it was found that the natural gas recovery factor in water-drive gas reservoirs is about 50-60%. Considering the significant volumes of residual gas reserves trapped by formation water, there is a need to improve existing development technologies and search for optimal ways to increase hydrocarbon recovery under conditions of intensive water encroaching. Additional researches using hydrodynamic simulations were conducted in order to study the efficiency of enhanced recovery of residual gas reserves by injecting non-hydrocarbon gases into productive reservoirs. Based on the 3D reservoir model, the study of carbon dioxide and nitrogen injection into the initial gas-water contact was carried out in order to slow down the breakthrough of formation water into productive reservoir. The study was performed for different injection duration of carbon dioxide and nitrogen into productive reservoir. According to the results of the statistical processing of the calculated data, the optimal duration of the nitrogen injection was determined to be 8,04 months. The ultimate gas recovery factor for the optimal period of nitrogen injection is 58,11%. At the time of the carbon dioxide breakthrough into production wells, the optimal duration of the carbon dioxide injection was determined to be 16,32 months. The ultimate gas recovery factor for the optimal period of carbon dioxide injection is 61,98 %. Based on a comparative analysis of the efficiency of using various types of non-hydrocarbon gases as injection agents into productive reservoirs, the high efficiency of using carbon dioxide for injection into the initial gas-water contact was established. Due to the solubility of carbon dioxide in formation water, the ultimate gas recovery factor is significantly higher compared to using nitrogen as an injection agent.

Published: February 2022

In connection with the trend of shortage of commercial fuels for engines in Ukraine and the world, the production of alternative fuels is developing, including biogas. The use of biogas fuel on a modern internal combustion engine equipped with gas equipment of 4-5 generations can create a number of difficulties. This is due to the low heat of combustion of untreated biogas, the presence of moisture and the specifics of the operation of the nozzles. And, therefore, for the correct choice of nozzles, it is necessary to conduct a study and analysis of a number of basic indicators of their operation and, based on the data obtained, recommend their optimal parameters. In gas nozzles, as in gasoline ones, there are a number of important parameters on which stability and uniformity of engine operation, fuel consumption, reliability, etc. depend. These include: linear operation; nozzle reaction time; coil resistance; response time; ability to maintain factory performance; resource of work. For research, we selected nozzles of 4 generations of common manufacturers, namely: Matrix; Barracuda; Valtek; Hana; Keihin. In terms of linea-rity, Valtek nozzles have low performance, and therefore use on engines can lead to increased biogas consumption, reduced engine performance and valve burnout. Keihin nozzles have high rates in this aspect of research, and therefore they will provide maximum efficiency of biogas combustion on the engine. High reaction time in Keihin nozzles. Barracuda nozzles are very close to working with Keihin, which means that their use will not impair engine performance. The factory characteristics of the nozzles, namely the coil resistance is the optimal Keihin nozzle, and the lowest values ​​in Valtek nozzles, the response (response) time of the Matrix, Hana and Keihin nozzles is quite close to 2 ms, which will provide quick response and wear, and the Barracuda and Valtek nozzles Keihin, Matrix and Barracuda nozzles provide the ability to maintain factory characteristics in the range from 2 to 5%, and the worst performance in Valtek is up to 20%, the service life of the nozzles, subject to timely servicing, is the largest Keihin nozzle, Matrix and Hana, which is from 200 to 250 thousand km, and the lowest indicator in Valtek and Matrix injectors is a resource from 70 to 100 thousand km. So, according to the results of the research, Keihin nozzles are recommended for use on engines in the process of their conversion to gas fuel. Their application will provide maximum efficiency and economy of the engine.

The rapid development of well construction technologies is inherently associated with the improvement of the technology that is used in this case. Tools of a new generation - bits with diamond cutters (PDC) - are widely used, in which technical and economic indicators are significantly better than roller cone bits. Although their design is well developed, the issue of optimizing the operation parameters of jetting nozzles, the design features of which determines the efficiency of well construction, remains relevant. Despite the effectiveness of the existing design of PDC bits, the study of hydrodynamic parameters was carried out using simulation modeling. Such a study makes it possible to assess the hydrodynamic parameters of the bit, develop recommendations for their improvement, which in turn will improve the efficiency of well construction in general. Computer programs designed for simulation of hydrodynamic processes make it possible to determine the necessary parameters with great reliability. However, the accuracy of the obtained result will depend not only on the settings of the grid of finite volumes, the number of iterations, but also on the initial data. Therefore, in the calculation model, in addition to the main parameters, such as the flow rate of the drilling fluid, the pressure at the bottom of the well, the bit rotation frequency, density, temperature and model of the drilling fluid viscosity, the roughness of the surfaces of both the bit and the walls, and the bottom of the well are taken into account. As a result of simulation, the drawbacks of the existing designs of PDC bits were identified, which can be eliminated using the proposed design of the jet nozzle, which: creates a large vorticity of the fluid flow, which positively affects the capture and removal of cuttings; makes it possible to regulate the direction of fluid movement (especially important for nozzles that are located farther from the bit axis), which will improve the removal of cuttings and, accordingly, will prevent it from re-entering the bottom
Improvement of classification of emulsion production methods
Authors: Melnyk V. О.
Published: February 2022

When burning liquid fuel, the problems arise related to ensuring the environmental requirements and the efficiency of its use. The process of high-quality liquid fuel combustion (mainly fuel oil) is complicated by the presence of excess water in it. One of the promising directions for solving this problem is the use of water-emulsion fuels (WEF), in which the expensive stage of fuel dehydration is replaced by the stage of emulsification – the uniform water distribution in the volume of fuel. In this case, it is possible to eliminate its stratification not only with the use of expensive surfactants, but also with the use of technologies, ensuring the stability of such fuel due to the formation of a finely dispersed emulsion. The stability and efficiency of combustion of such a fuel emulsion (FE) will significantly depend on the amount and water dispersion in the WEF. Nowadays such WEF technologies for emulsifying and their features are insufficiently studied and therefore have great scientific and practical importance. The existing classifications of emulsification methods (EM) are diverse, which makes it impossible to analyze the possibilities, functionality, and practicability of choosing the optimal EM for obtaining a high-quality emulsion. On the basis of the analysis of the existing EM classifications, the improved classification is proposed, which combined the possible EM and devices. The expediency of using a specific EM depends on the parameters of the FE and its needs, scope, conditions and purpose of application. It is effective to use for an industrial scale the devices that work with discrete-pulse energy input technology (DPEI). However, you can use the sound EM, using the UZDN-A disperser and the UZG-34 generator for laboratory studies.

This is due to the fact that the combustion of methanol in the diesel cylinder does not form intermediates that promote the formation of acetylene and aromatic hydrocarbons, which lead to the formation of soot. Methanol is a renewable natural resource, ie there is a large raw material base to increase its production and much wider use as an energy source. Using of this alcohol as an alternative biofuel for vehicles is possible as a result of its production in affordable and cheap ways from agricultural and food waste, from gaseous fuel.  Fuel   energy   and   engine   power   were   increased   by   regenerating   the   heat   of   the   exhaust   gases.   Experimental   studies   of   power   and   economic   performance   of   a   diesel   engine,   which   was   converted   to   work   on   the   products   of   methanol   conversion.   Experimental   studies   have   shown   that   the   conversion   of   diesel   engines   to   work   using   methanol   conversion   products   is   justified.   Given   that   the   price   of   methanol   is,   on   average,   10-20%   of   the   cost   of   diesel   fuel,   the   conversion   of   diesel   engines   to   work   using   methanol   conversion   products   is   quite   profitable.

Published: February 2022

The research has shown that in the Inner Zone of the Pre-Carpathian foredeep as a whole and the Boryslav oil field in particular, oil and gas condensate fields are located naturally due to the spread of deep faults within. It is established that oil and gas deposits of fields represent a set of sand lenses within a certain complex of flysch rocks, the increased oil saturation of which is associated with fracture. The obtained results showed that the oil deposits in Boryslav sandstone have a lenticular structure, and the high productivity of wells is associated with the vein form of hydrocarbons in the sand layers. In order to determine the nature of productivity Boryslav sandstone, we modeled a map of integrated oil production from deposits in Boryslav sandstone from Boryslavska deep fold, which shows all the wells that opened this layer. It is established that in the area, which covers only 0.8 of the area of Boryslav sandstone (eastern part of the field), from the wells that exploit it, extracted 15% of the total oil production from the Boryslavske field as a whole. At the same time, the distance between the most productive wells is only 110 m. Also, on the same site between high-performance wells at a distance of only 50-100 m there were also those in which from Boryslav sandstone oil inflows were not received at all. It is characteristic that industrial inflows of oil are received from small intervals (1-2 m) in the cross-section of 20-30 m of a powerful sandy horizon. The intervals of tides could be both in the roof and in the plantar part or in the middle part of the formation. While in some areas and even in the vaulted part of the folds (theoretically the most promising for anticlinal folds) tides are not obtained at all. We believe that for effective exploration of Boryslav oil field it is necessary to change its methodological basis. Namely, exploration wells must be drilled based on the location of wells that gave an industrial influx of oil, placing them gradually at short distances.

Published: February 2022

According to the results of studies of steady operation modes of electric pumping units of Ukrainian oil pumping stations, have been identified the main reasons of efficiency decrease of their performance during operation. It is determined that the normative documents regulating the efficient operation of pumping units of the main oil pipelines of Ukraine need to be improved. The assessment of energy efficiency potential of the main pumping unit on the example of pump НМ-3600-230 with synchronous electric drive СТД-2500-2 is carried out and the main ways to increase the efficiency of electricity use at oil pumping stations of main oil pipelines are analyzed. A complex mathematical-graphic model of a centrifugal pump and a synchronous electric motor is used to determine the parameters of the process of energy consumption and energy use of hydraulic and electrical subsystems of the pump unit, which allowed to take into account possible changes in equipment characteristics and modes of operation. The value of the relative specific consumption of electricity for pumping of working fluid for regulated and unregulated electric drive based on a complex electro-hydraulic model of the main pump was calculated, which allowed to promptly recalculate the characteristics of the centrifugal pump and electric motor taking into account their technical condition and to determine the potential of the pumping unit. It is determined that an effective way to reduce energy consumption by main pumping units is applying of a controlled electric drive at oil pumping stations, but the feasibility of such a measure requires additional technical and economical calculations. It is determined that to increase the efficiency of pumping units is necessary to avoid low flow-duty modes, to form maps of main oil pipelines in a way to ensure optimal in terms of energy efficiency operation modes of electro-hydraulic equipment of oil pumping stations and to change operation mode of pump and motor in terms of their technical condition.

Today considerable experience in the development of tar sands is accumulated. However, well-known mining technologies do not cover the entire depth range of natural bitumen deposits. In addition, there are significant energy-intensive technol 309 ogies and negative environmental impacts. In view of this, the purpose of this work is to improve the method of extracting natural bitumen in site for a deposit interval of 75-200 m and to substantiate the basic technological scheme of this method. The proposed method of extracting bitumen from poorly cemented reservoirs in the depth range of 50 – 400 m provides: creation of artificial production; the transfer of the rock into the water mixture composition under the action of high pressure jets of a heated mixture of water, a hydrocarbon solvent and a flotation agent; separation from the rock and concentration of bitumen in the production as a result of its heating, dissolution and flotation; selection of depleted bitum slurry from the production by gas lift. The proposed method of extracting bitumen is the transfer of the rock at the its occurrence site to the suspension condition on the excavation created by the hydraulic production method, separation and concentration of bitumen by dissolving it with a heated hydrocarbon solvent and a flotation agent (hydrocarbon reagents) and extraction in composition of the depleted rock slurry to the surface by the gas lift method. As the preliminary calculations show, the proposed method will allow the efficient extraction of bitumen and highly viscous oil from weakly cemented reservoirs in the depth range of 50-400 m. Also, the proposed technology creates the preconditions for the development of oil sands at a depth of 75-200 m since there is currently no effective technology for the interval. In addition, it can significantly reduce energy costs, environmental pollution and greenhouse gas emissions.

In construction practice, for the construction of foundations without excavation and formwork, the methods of ramming and stamping of the soil base can be successfully used. Under ramming means the formation of a depression by directional dropping from a certain height of the rammer, which has the shape of a future depression, and under stamping, the formation of a depression by driving a template stamp to the required depth and then removing it from the ground. The resulting recess is filled with concrete directly or a prefabricated element is installed in it. The use of these methods makes it possible to reduce (by 3...6 times) the volume of earthworks in comparison with the traditional methods of construction of foundation pits. The presence of a compacted zone at the base and around the sidewalls of the recess can significantly reduce the size of the foundations and reduce the consumption of concrete by 1,2...2 times, and reinforcement - by 1,4...4 times. To increase the bearing capacity of the upper soil layers and in order to eliminate the effect of frost heaving of the soil into the walls and bottom of the deepening, waste from the mine, mining and processing industry is rammed in separate portions in the form of crushed stone, sand and gravel mixture, coarse sand, screening and other materials. The energy and number of strokes of the stamp are determined by the required depth of the deepening and the type of soil. The questions of the rational shape and size of dies, technical and technological parameters of machines and equipment for the installation of recesses for the foundations of rapidly erected technological mine structures, taking into account the technogenic local soil bases and "waste" rocks, remain open. Below is a description and analysis of methods for constructing recesses for foundations without excavation, the results of research and the creation of highly efficient working equipment are given. Recommendations are given on the choice of the parameters of the working equipment for the formation of depressions in the base with a seal.

The condition of infrastructure facilities is directly dependent on the engineering and geological conditions of their location. Natural transformations are usually rather slow and are often determined only by consequences. The rate of destruction under the influence of man-made factors significantly exceeds the rate of natural development of the geological object. The main purpose of allocating engineering 578 geological classes (at the regional level) is to identify the most dangerous objects at the local level that require priority engineering intervention. The aim of the study is to identify, map and forecast the patterns and dynamics of negative changes in the geological environment and its main parameters which directly or indirectly affect the state of territories, regions, state as a whole for planning and monitoring the geological environment. The paper proposes an approach to the implementation of the assessment of the state of the geological environment and developed a system of criteria and indicators of assessment, both as a whole and its individual components. The obtained maps can be used not only to study the conditions of activation and development of hazardous processes, but also for engineering and geological substantiation of measures to prevent and prevent the destruction of foundations and foundations, select priority areas for priority intervention and engineering protection of infrastructure and serve as a basis for planning and monitoring the geological environment.
