The authors created a geodynamical polygon on the Komsomolsk oil and gas condensate field to ensure the industrial safety of oil and gas production facilities. The aim of its creation is mul-tiple repeated observations of recent deformation processes. Analysis and interpretation of the results of geodynamical monitoring which includes class II leveling, satellite observations, radar interferometry, exploitation parameters of field development provided an opportunity to identify that the conditions for the formation of recent deformations of the earth’s surface is an anthropogenic factor. The authors identified the relationship between the formation of subsidence trough of the earth’s surface in the eastern part of the field with the dynamics of accumulated gas sampling and the fall of reservoir pressures along the main reservoir PK1 (Cenomanian stage).

When drilling deep oil and gas wells with large deviations from the vertical stope the resistance when moving the drill string in borehole significantly increases. A consequence of this is the difficulty of control screw steerable motor. Minimizing resistance forces is possible through usage of a J-shaped profile. The authors present the technique and results of calculation of layout, ensuring reliable integration of the trajectory of the well. This is achieved through the contact link to the bottom of the borehole wall in four locations, including a chisel, curved subs and two pillars.

Achimov sequence is characterized by high heterogeneity and low reservoir properties, that makes it impossible economically profitable field development without hydraulic fracturing and usage reservoir pressure maintenance systems. The research aims to develop recommendations for regulating the operations of injection wells, in conditions of waterflood-induced fracture formation. The recommendations can be used to further regulate the waterflooding system for the conditions of Achimov sequence.

The article presents a technology for building a water-shut screen in an oil well. The technology is based on drilling of radial channels within the water-encroached formation and following injection of water insulation composition in these channels. The proposed technology provides a durable screen of increased diameter and width. It contributes to a longer period of low watercut production in an oil well.

Secondary opening of productive oil and gas reservoirs by using cumulative and bullet perfo-ration methods in directional wells with high values of inclination angles (40-60º) requires a solution of technological problems caused by the justification of the interval of their implementation. This is especially important for multi-layered reservoirs with alternating water saturated and oil saturated horizons and the absence of an insulating low-permeability screen, for example, a clay layer (tire). The article makes an attempt to attract geological services, owners of companies that develop deposits with such conditions, in order to increase the requirements for the appointment of a perforation interval. The authors give some proposals based on the actual results of well con-struction.

The article deals with a downhole universal device for pulsed stationary pumping of fluids into the well. The versatility of this device is concluded in the ability to create a high-frequency vibra-tions in case of an injection well injectivity decline due to use of an additional element. On the basis of mathematical expressions and taking into account the simulation the authors determine the main parameters of the device. In developed laboratory bench tests experimental design was carried out taking into account the modeling of downhole conditions. When comparing the theoretical and laboratory results, the error was no more than ± 11,7 %. According to the results of bench tests the optimal size of the device for effective action at a pulsed stationary pumping of fluids into the well was determined.

The method of parallelizing a numerical solution of the complete system of Navier - Stokes equations is used to describe three-dimensional unsteady flows of a viscous compressible heat-conducting gas in ascending swirling flows. In this case the action of gravity and Coriolis forces is taken into account, and the coefficients of viscosity and thermal conductivity are assumed to be constant. The results of the numerical construction of instantaneous streamlines characterizing complex three-dimensional flows are presented for simulation the steady-state output of an ascend-ing swirling air flow in an artificial tornado.

The article explores the influence a storage time on the samples of pure ice powder and mod-ified ice powder with polyvinylpyrrolidone on process formation and growth of the gas hydrate by used P-V-T measurements. It has been established that increased storage time of the pure ice powder leads to a decrease the rate of growth of gas hydrate. Fresh modified ice powder has induction time of hydrate formation which increased in a polyvinylpyrrolidone concentration. At long-term storage of modified ice powder with a polyvinylpyrrolidone concentration less 0,3 % the induction time don’t registrate and growth rate of gas hydrate likes zero. In the samples of modified ice powder with a polyvinylpyrrolidone concentration more 0,75 % after 10 days a storage were retained growth rate of gas hydrate likes fresh modified ice powder. There is no induction effect.
