Abstract
On the basis of flow modeling the impact of injectioninduced fracturing on the cumulative oil production value is examined in dependence of the oil and water mobility ratio under conditions of homogeneous and heterogeneous permeability of reservoir. It is established that the presence of injection-induced fracture in the near-wellbore area of the injection well can have a positive influenceon the dynamics of production fluid. Complex approach to estimation of probability of injection-induced fractures presence and algorithm of determination of their geometric parameters areal so proposed.

Abstract
Operation time of the well before stopping for investigating the pressure recovery curve in hydrodynamic studies is an important parameter affecting the quality and accuracy of results of research processing. Comparing the actual and theoretical pressure curves and the derivative, it’s possible to eliminate the uncertainty in the choice of previous history of the well operation.

Abstract
Analysis of osmotic and ion exchange processes between injected agent and clay-containing rock has been carried out. The analysis allowed to obtain reservoir properties depending on ionic composition and salinity of the injected water and ratio of clay-content of reservoir. It’s been shown that change of hydrochemicalmode of formation development leads to transformation of structure of porous medium, and as a result to changes in reservoir porosity and permeability properties. Analytical dependencies of porosity and relative phase permeability on the salt concentration and ion composition of injected fluid have been obtained on the basis of micromechanical description of fluid flow process in porous medium. The modeling of two-phase Newtonian fluids flow in clay-containing porous medium has been carried out. Influence of parameters of porous medium and injected saline liquid on oil production has been researched. Efficiency of low salinity solutions and highactive metals solutions injection in clay containing reservoir has been shown.

Abstract
At cementing of casing of oil and gas wells during the process of injecting of cement slurry in the casing column the slurry can move with a higher speed than it’s linear injection speed. A break of continuity of fluid flow occurs, what can lead to poor quality isolation of producing formations and shorten the effective life of the well. We need to find some technical solution to stabilize the linear velocity of the cement slurry in the column. This task can be resolved with an automated control system.

Abstract
The paper describes the method of isolation of bottom water inflow in oil wells. The method of isolation of inflow of formation water in the well, watered by water cone flowing into the near-wellbore area, is drilling is carried out from the main borehole of the stopped well into the productive formation with water intrusion into radial offshoots along the radiusbelow of the well perforation interval. They pump the waterproofing composition into referred radial offshoots with the creation of the waterproofing screen along the radius of the main wellbore. They leave the well for a period of reaction of composition injected under pressure and perform a subsequent well completion through existing perforations of the perforated interval.

Abstract
The paper presents a method for calculating the gas stream flow rate during well tests of gas and gas condensate wells using a diaphragm gauge of critical flow. The above method compensates the disadvantages of the described in the scientific and technical literature gas stream flow rate calculation methods during its flow through the diaphragm in the critical regime. For the proposed method are presented the testing results on gas and gas condensate wells of the north of the Tyumen region.

Abstract
IR spectroscopy investigated structural and group composition of base mineral oils isolated from the vacuum distillate by selective purification of N-methylpyrrolidone and the low temperature dewaxing in the presence of a solvent. The role of the latter was carried out by the systems acetone - toluene, acetone - methyl tertiary butyl ether, methyl ethyl ketone - toluene, acetone - toluene - modifying additive. It was shown that the chemical composition of the group of base oils and slack waxes is defined as the nature of the solvent to the dewaxing, and oils sequence of purification steps.

Abstract
Sophisticated viscous compressible heat-conducting gases arising during heating the vertical field, have a pronounced axial symmetry. Therefore, for the numerical solution of the full Navier-Stokes equations to describe such gas flows is advisable to use a cylindrical coordinate system. This paper describes the transformation of the third projection of the equation of motion of the full Navier-Stokes equations. The result of the transformation is to record the third projection of the equation of motion of a continuous medium in a cylindrical coordinate system.

Abstract
For definition of stresses and loads through measured displacements of pipeline axis it is necessary to calculate derivatives of approximate function. The error of defined stresses is in direct dependence on order of derivatives, necessary for their definition. Application of Timoshenko beam theory allows to reduce the order of derivatives. It is possible to improve the accuracy of stress and loads definition.
