METHOD FOR DEVELOPING OIL-GAS DEPOSIT WITH APPLICATION OF HYDRAULIC FRACTURING OF BED Russian patent published in 1999 - IPC

FIELD: oil production industry. SUBSTANCE: according to method, injected through injection wells is water and/or gas and/or other displacing agent. Hydraulic fracturing of bed is effected by artificial inside-contour treatment of object under development. Hydraulic fracturing of bed is performed through entire combination of injection and producing wells. Bed fluid is withdrawn through producing wells. Studying and realization of hydraulic fracturing of bed are made on basis of continuous information about mechanical properties of rock matter in cross-cuts of injection and producing wells. This information is correlated with geophysical investigations. Direction of fissures resulted from hydraulic fracturing of bed is preset by selection of zenith and azimuth angles of injection and producing wells with no account of non-uniformity of filtration flows. Period of effective functioning of fissures resulted from hydraulic fracturing of bed is prolonged by injecting into fissures of compositions of materials with physical and chemical properties for solving clayey and other mineral substances which fill fissures produced by hydraulic fracturing of bed. EFFECT: higher efficiency. 1 cl
