Granted: 1997-12-20
Abstract: FIELD: oil producing industry. SUBSTANCE: method includes withdrawal of oil through producing wells and injection of working agent through injection wells. In watered zone of pool, stimulated wells are chosen, while in oil zone, responding producing wells are chosen. Well fluid in chosen stimulating wells is replaced with hydrocarbon fluid with density of 0.7-0.8 g/cu.cm. The periodic fluctuations of well production rate are effected. Upon completion of three periods of fluctuations responding wells are shut-in. Well fluid is changed for hydrocarbon fluid with density of 0.7-0.8 g/cu.cm. Pressure variation is measured during two periods of fluctuations. Harmonic analysis is carried out of the production rate and pressure versus time on stimulating wells and pressure versus time of responding wells. Phases and amplitudes of harmonics of these fluctuations are determined. Formation pressure on the development section is increased and decreased within the range up to 4 MPa from hydrostatic one. The same characteristics are determined at varied formation pressures. Interval of formation pressure is determined at valued of maximum formation water permeability and efficiency operating thickness of formation are attained. Well operation is varied for realization of this interval. Bottom-hole pressure in producing wells is maintained not less than and in injection wells not more that 4 MPa relative to determined interval of formation pressure. EFFECT: higher efficiency. 2 cl, 2 dwg , 7 tbl
