Some results of the studies performed in the framework of the RAS Presidium Programs “Fundamental basis of new technologies in the oil and gas industry” and “Oil from the deep horizons of sedimentary basins as the main source for replenishment of the raw hydrocarbon resource base; theoretical and applied aspects” that are implemented by RAS researchers in new scientific-methodological and technical solutions seeking promotion in FEC enterprises are presented. Special attention is paid to the problems of oil and gas extraction, such as increase of the oil recovery coefficient, improvement of the contents of information about core samples, and hard-to-extract reserves (highly viscous oil, low permeable reservoirs, shale oil and gas). Theoretical principles of the technology of influence on the oil and gas deposits in anisotropic structures are elaborated. It is shown that the relative phase permeabilities depend not only on the saturation, but also on the direction of displacement. A new method for complex lab-study of the anisotropic samples is revealed to determine the absolute and relative phase permeabilities. Technologies are developed to resolve the problems of reduction of the water and solid phase contents in the well production, increase in the well debit and oil recovery coefficient as a result of the task-oriented choice of operations and parameters of the influence.
Keywords: anisotropic rocks, deformation processes, phase permeabilities, lab- and field experiments, sand-control and crack-formation technologies.
