Authors: Yun Yu , Xinxin Gao
Published: January 2021

Based on the observation data of Binhai and Lvsi stations in the past ten years, this paper analyzes the temporal and spatial distribution characteristics and formation conditions of sea fog along the coast of Jiangsu Province, and obtains some rules, such as: winter and spring are the seasons of frequent sea fog along the coast of Jiangsu Province, when the relative humidity is≥85%, the temperature difference between water and air is within plus or minus 8°C, when the southeast wind is easier to form fog, and the wind speed generally does not exceed 5 levels. In addition, the sea fog in Jiangsu coastal area can be generally divided into inverted trough type, low pressure type, cold air type and high pressure type, and it is easy to form fog when inverted trough. Continuous multi-day sea fog is often the continuous influence of various weather situations. All these provide ideas for the prediction of sea fog in Jiangsu coastal area.

Study on fracture propagation and interaction mechanism during hydraulic fracturing
Authors: Zheng Peng , Zhou Desheng
Published: January 2021

With the widespread application of hydraulic fracturing technology, the corresponding numerical simulation methods have been rapidly developed, and we have a deep understanding about the fracture propagation trajectory during hydraulic fracturing at the same time. However, the fracture interference mechanism during hydraulic fracturing is still insufficiently understood. Based on linear elastic fracture mechanics and relevant fracture criterion, a simulation model was established to simulate the fracture propagation by using boundary element method. The interaction mechanisms between fractures are studied. Results show that hydraulic fractures will change distribution direction of formation stresses during propagation process, and asymmetric fractures tend to merge together during propagation. The reverse propagation phenomenon between two fractures in numerical simulation rarely exists in the actual formation. The analysis and research on the mechanism of crack propagation and interaction can provide a theoretical basis for the trajectory control of hydraulic cracks in the later period.

Published: January 2021

In order to clarify the toxic effects of petroleum hydrocarbons in sediments on bivalve mollusks, the acute toxicity and effects of petroleum hydrocarbons on antioxidant enzyme activities were studied using Maoctra veneriformis as a test organism. Our results showed that the health status of the Maoctra veneriformis gradually weakened with the increase of exposure time and concentration of petroleum hydrocarbon, and mortality occurred in the high-concentration group at the end of the exposure. The activities of peroxidase (POD) showed a trend of first decrease and then increase with the prolong of exposure time, and POD activity was significantly induced in some concentration groups at the beginning and the end of the exposure (P < 0.01). The activities of superoxide dismutase (SOD) generally decreased first and then increased as the petroleum hydrocarbons concentration increased. With the prolong of exposure time, the SOD activity decreased first and then increased and then decreased. Our results showed that petroleum hydrocarbons in the sediment produced a certain toxic effect on Maoctra veneriformis, and there was a certain time-dose-effect relationship between anti-oxidase activity and petroleum hydrocarbons. Meanwhile, petroleum hydrocarbons can produce significant induction or inhibition effect on anti-oxidase activity.

Published: January 2021

Because of the situations that the interconnection among multi distributed energy system (DES) and interaction among electric, heating and cooling system are not given full consideration, optimal planning of energy internet near user side based on bi-level programming is studied in this paper. First, schematic structure along with mathematic models of each unit is proposed and load characteristic is analyzed. Considering the interconnection of multiple energy as well as multiple distributed system and the combined dispatch of multi energy flow, a bi-level programming model is then presented. The minimum of total annual cost is the objective of upper model whose decision variables are the capacity of each energy unit and minimum annual operating cost is the lower model’s objective whose decision variables are the output of all energy units. Then, the elitist strategy genetic algorithm is employed to solve the upper model, and branch and bound algorithm is applied to optimizing lower model. The simulation results indicate that the proposed planning method of energy internet is effective, multiple energy flow interaction and multiple energy router interconnection are more economic than traditional combined cooling heating and electricity (CCHP) and can alleviate the mismatch of heat-to-electricity ratio between gas turbine and loads, and the multiple energy networks by which DES are interconnected contributes to higher economic benefits than single electric or heating network.

Published: January 2021

Ensuring the energy and food independence of each state will not only remain important but that its importance will continue to grow given the constant need for the state to properly guarantee the basic needs of the population. However, the rapid development of bioenergy is a potential precondition for the fuel and food conflict over agricultural raw materials. The article examines the relationship between food safety indices and the overall share of energy from renewable sources and bioenergy production in 3 European countries. The main factors characterizing the food security of these countries for the period from 2012 to 2018 are identified. Statistical methods of correlation analysis are used to determine the links between the outlined factors. It is studied that in most countries the prosperity of the bioenergy sector of agricultural enterprises does not affect the main indices of food security. In 5 countries (Poland, Germany, Norway, Spain, the Czech Republic) correlations were found, but for the most part, they are direct. It means that large values of one variable are associated with large values of the other, in other words with increasing the share of bioenergy production and overall share of energy from renewable sources, food safety indices also increase.

Published: January 2021

Due to the deepening imbalances in the development of world energy and the uneven distribution of traditional energy resources, countries are forced to apply innovative forms and methods of radical changes in the structure of energy consumption. The formation of energy independence is based on the use of the innovative potential of the economy and the introduction of renewable energy sources. The econometric analysis showed a high level of influence of energy consumption based on wind and solar energy, the share of energy supplies from renewable sources, imports of mineral fuel, oil and its distillation products, financing of innovative activities of industrial enterprises on the country’s GDP in a multifactor model. The implementation of innovative restructuring of the energy sector will reduce the level of energy intensity of GDP, increase the share of energy derived from renewable energy sources and reduce the consumption of traditional energy resources, which will provide an appropriate level of energy independence. The assimilation of complex world-class innovations in the field of energy determine the criteria of energy efficiency, encourage the active implementation of such measures, through which it is possible to predict the results of further scientific and practical search.

Published: January 2021

A comparative analysis of hydrate formation inhibitors of different types: thermodynamic, anti-agglomerate, kinetic action was performed. The advantages and disadvantages of each class of reagents are considered. The possibility of using highly mineralized reservoir waters to prevent hydrate formation in gas condensate fields is proposed. Laboratory studies were conducted to determine the decrease in equilibrium temperature in the presence of reservoir water of the well 202 of Zakhidno-Radchenkivske gas-condensate field. Experimental determination of the equilibrium parameters of the hydrates formation of technical propane for the studied formation water showed that the value of ΔT is higher than predicted. This paradoxical effect can be explained by the multicomponent combination of formation water and, probably, the synergistic action of its micro-and macro components. The results of the calculation of the antihydrate properties of the reservoir water of Zakhidno-Radchenkivske gas-condensate field are presented. The results of industrial tests of using reservoir waters for the prevention of hydrate formation in the gas preparation system at Zakhidno-Radchenkivske gas-condensate field are presented. The results of industrial tests confirmed the effectiveness of the formation of reservoir water to prevent the formation of hydrates: hydrate formation in the well and on complex gas treatment unit was not detected. In addition, due to the use of well production, the cost of preparing gas for transportation has been significantly reduced. The article substantiates the possibility of using formation waters of oil and gas fields of the south-eastern part of the Dnieper-Donetsk basin as an inhibitor of hydrate formation.

Published: January 2021

This article is the result of generalizing a real practical problem of optimizing the operation of a cold supply logistics network. A small (up to 100 clients) logistics company solves the problem of operational planning: during the working day (fixed time window) to provide the supply of cold (food) products from distribution centers to end consumers along well-defined routes (i.e., the logistic network graph is fixed). The company has set the following conditions for the authors. In addition to minimizing the usual transport costs, take into account also the environmental costs (associated with negative consequences for the environment) that arise during the operation of the logistics supply network. And also when deciding to use software available to the company. The case is considered when the transport tariff on each route is a linearly increasing function of the total volume of all traffic on this route. When the Nash equilibrium conditions are met, the mathematical model for optimizing the total costs of the logistics network is reduced to a convex (quadratic) programming problem. Computer implementation in MS Excel environment has been carried out. This makes it possible to carry out simulation calculations for various options for transport costs on routes, taking into account environmental costs.

Despite the wide range of scientific research on the subject and their actuality, there is no generally accepted concept of competitiveness today. In summarizing and generalizing different viewpoints, competitiveness will be understood as many sustainable advantages of a research object compared to its external environment. The scientific novelty of this work is the development of a model of the sectoral index of competitiveness by environmental component, which allows to carry out a comparative analysis of types of economic activity and to develop programs for the development of sectors taking into account anthropogenic impact.

This article considers the role of the sustainable development concept in the tourism destination areas. The existing of tourism gives many benefits to such areas, but it also causes and aggravates the environment problems, leading to the degradation of natural capital. To deal with these problems, modern science suggests to implement sustainable initiatives in the regions, making their infrastructure more sustainable. It was shown that it is the responsibility of business and a local government to bring the green projects to life, but there is need to take into account the tourists’ interests. The tourists’ awareness of the sustainability concept and their demand for the sustainable products have been studied. The main goals of this paper are to look at the current state of the dealing with the issue and to outline goals for the future researches in this field. It was found that there is significant demand for sustainable and environmentally friendly tourism and implementing it on the tourism destination areas will help to gain the advantages in the long run.

The article explores the problems of sustainable development of the natural mineral resources market in the context of digital transformation of the industry. Key trends in the development of the global mineral resources market in economic, ecological, energy and digital dimensions have been identified. The features of the world distribution of raw material base of ore and energy mineral resources in terms of their economic assessment have been studied and the countries - market drivers - have been identified. A model for sustainable development of the mineral resources market and a system of criteria for its assessment in the context of Industry 4.0 have been proposed. In particular, the link between the level of digital technologies and the energy trilemma has been analysed. Based on the results of the calculations, the grouping of the leading countries in the mineral resources market by the level of achievement of sustainable development has been carried out and ways to digitize the mining industry have been outlined.

The peculiarities of the current stage of the functioning of the economic system of Ukraine are due to the intensification of industrial and agricultural production and, as a consequence, the operation of environmentally “dirty” technologies, their high energy and resource consumption. On the other hand, the low rate of development of the national economy, caused by internal and external destabilizing factors, leads to the use of limited investment resources in the environmental sphere, which poses a threat of environmental crisis. In this regard, the issue of assessing the state of environmental safety at both national and regional levels is becoming especially relevant. The use of modern analytical tools, in particular, methods of multidimensional statistical analysis, will help create a scientifically sound basis for the prevention and reduction of the negative consequences of the implementation of environmental threats to regional security. We proposed the use of cluster analysis technology to group regions by the level of environmental safety. The typology of regions was carried out in five clusters. The content characteristics of each cluster are presented. The absence of structural changes in the clustering of regions during the last two years was shown. The application of factor analysis methods for the same set of initial data generally confirmed the results of clustering.
Criteria for sustainable development of the system through risk assessment

Based on modern developments in risk theory, it is proposed to identify two objectives of system risk management: the first (strategic) goal is focused on ensuring (maintaining) sustainable development of the system; the second (current) goal involves keeping the amount of risk within acceptable limits for the functioning of the system. Regarding the diagnosis of the activity of a particular object of study, the concept of stability can be used to characterize the stability of its position in an unstable environment. There are two areas of stability assessment: the stability of the environment and the stability of the system. Based on the considered properties of the beta coefficient, it is proposed to use the modified formulas of this indicator for diagnostics of stability and diagnostics of development within the mechanism of risk diagnostics of different levels of management. These formulas can be used for estimation of separate indicators, groups of risk factors, or risks of the object at whole. Evaluation of indicators in accordance with a certain diagnostic criterion takes into account the dynamics of values, therefore, the authors considers the calculation of the chain growth rate of indicators in index form for the relevant (identical) periods of time as the best option for standardization.
