Abstract: FIELD: oil and gas industry.SUBSTANCE: invention relates to the field of the oil and gas industry and can be used in the development of multi-layer hydrocarbon fields. The method for developing multi-layer gas fields includes the construction of well clusters of several vertical, inclined-directional and horizontal wells for different layers of the field. At the same time, wells operating different layers of development have a different spatial profile, gas flow control devices are installed at the wellheads, wells are connected to a single pipeline network and field development begins with the exploitation of lower gas reservoirs with a higher initial reservoir pressure. Upstream reservoirs are included in the development when the current wellhead pressure of wells draining the lower reservoirs decreases to the initial wellhead pressure, and if necessary, by increasing the flow section in the control devices, the gas flow in the wells of formations with higher reservoir pressure is increased without a long wait for a decrease in reservoir pressure in these formations.EFFECT: invention allows increasing the recovery coefficient of reserves and increasing gas production while simultaneously operating wells with a lower reservoir pressure of formations.1 cl, 2 dwg

Abstract: FIELD: agriculture. 
     SUBSTANCE: invention relates to the field of agriculture, in particular, to arable farming and crop cultivation. The method includes consecutively executed stages of forming at least a testing and control variants of crop seed samples, ensuring contact of the testing seed sample with soil with the addition of water until the lowest moisture capacity of soil is reached, ensuring contact of the control seed sample with sand with the addition of water until the lowest moisture capacity of sand is reached, holding said testing and control seed samples until germination, removing soil and sand from the germinated seeds. In each sample variant, the germinated sprouts are separated from the root system, the cut sprouts and, separately, the root system with the remaining seeds are weighed. For each control and testing samples, a dimensionless coefficient of the ratio k of the weight of the green mass of germinated sprouts m g  to the weight of the root system with the remaining seeds m kc  is determined by the formulas     wherein m g0-S  is the weight of the green mass of germinated sprouts in the control sample (sand), m kc0-S  is the weight of the root system with the remaining seeds in the control sample (sand), m gi-S  is the weight of the green mass of germinated sprouts in the testing samples (soil); m kci-S  is the weight of the root system with the remaining seeds in the testing samples (soil), i is the number of a particular soil, S is the name of the variety. The soil fatigue indicator is then calculated, taken as the ratio of the resulting dimensionless coefficients for control and testing samples, by the formula   and based on the value of this soil fatigue indicator, a conclusion is made on the degree of soil fatigue as applied to a specific crop, a specific crop variety and the potential development of a specific crop and a specific crop variety on a specific soil. 
     EFFECT: method provides an increase in the accuracy of estimating the soil fatigue, simplification of the process, reduction in the time and labour consumption and an obtained possibility of predicting the potential development of a specific crop variety on a specific soil.

Abstract: FIELD: oil industry. 
     SUBSTANCE: invention relates to the oil industry. The method for developing a reservoir of high-viscosity oil or bitumen includes the construction of pairs of horizontal production and injection wells located one above the other, equipped in the horizontal part with liner filters, heating the reservoir by injection of steam into both wells with the creation of a steam chamber, subsequent injection of steam through injection wells, product selection for account of steam-gravity drainage through production wells and control of the state of the steam chamber. After depletion of a section of a deposit in one of the pairs of wells, steam injection and liquid withdrawal are stopped. After the temperature in the production well has dropped below 80°С, new boreholes are built from the production and injection wells with a horizontal section equipped with a liner filter in the direction of the areas of the reservoir not covered by development. At the same time, the wellbore is isolated, located below the exit level of the additional wellbore, under which a whipstock is installed in the well for cutting out a window and building a new wellbore. New wellbore exits are positioned above the corresponding horizontal sections of the new wellbores to provide descending sections between the wells and new horizontal sections. From an injection well, a new borehole is constructed with a horizontal section above a new horizontal section of a production well at a distance that provides a hydrodynamic connection between the boreholes after warming up, but excludes steam breakthrough. Steam is injected into both wells to obtain a hydrodynamic connection between the new wellbores. Then steam is injected through a new borehole of the injection well and the product is taken out through the new borehole of the production well with control of the state of the steam chamber. 
     EFFECT: recovery of residual oil reserves, facilitation of liner and downhole equipment commissioning, elimination of emergencies associated with the extraction of liner filters.
