Abstract: In the present paper various variants of the presentation of the Reynolds' number and the coefficient of hydraulic resistance for the porous media with isotropic and anisotropic reservoir properties are presented. The development of formulas and the analysis of variants are carried out on an example of the modeling porous media with periodic microstructure which are formed by the system of capillaries and the packing of spheres with constant diameter (ideal and fictitious porous media respectively). Ideal porous media are modeled by capillary channels with different cross sections (circle, triangle, ellipse and rectangle). It is shown that formulas for the coefficient of hydraulic resistance for the fluid flows in capillary models coincide with formulas which are used in the pipeline hydraulics at the correct determination of Reynolds' number. The derived formulas in the aggregate with taking into account microstructure make it possible to explain wide scattering of the numerical values of Reynolds' number at the experimental data handling.

Abstract: The development of the first Messoyah field of gas hydrates is analyzed. Mathematical modeling allowed to determine that the volume of gas resulting from hydrates decomposition accounts for 30-50% of initial gas reserves in the hydrate state. Therefore further development of the Messoyah field is of great importance for major consumers: the town of Norilsk and GP Norilski Nikel. Patented technologies of gas extraction applicable to residual Messoyah gas hydrates are proposed

Abstract: In his article the statements of optimal allocation of gas extractions and his injection volumes for the underground gas storage wells problems are offered. Solution of these problems is reduced to construction of well production rates and pressures drawdown values dynamic (versus time) at stage of gas production from the underground gas storage (well injectivities and repressions dynamic at stage of gas injection). Solving formulated problems, well rates and pressures drawdown constraints or injectivity and repression constraints for gas production and gas injection respectively as well as total production (total injection) requirements with minimal total well produce water cut (maximal gas-water contact moving away well bottomhole) are allowed

Abstract: The article considers the calculation of the main parameter of two-phase mixture ϕ flow in the gas-liquid jet pump with the uncompressible fluid being the working fluid and compressible gas being the ejected medium. The calculation uses one-dimensional equations of heterogeneous media flow mechanics and experimental data taken from literature. A differential equation for real gas content was obtained on the basis of the equations of two-phase flows and a form of function ϕ in the jet pump nozzle was found on the basis of experimental data [2, 3].
