FIELD: oil production industry. SUBSTANCE: it can be used for development of nonuniform oil deposit. According to method, at later stage of development of deposit, section is selected which is limited by lithological replacement for non-reservoir, outer contour of non-saturation and rows of injection wells. Working agent is injected in cyclic operation. Selected in development section for injection of solution of polymeric material are injection wells located inside selected development section and close to producing wells with high output. Solution of polymeric material is injected. Periods of cyclic mode of injecting working agent are increased by 2-3 times. Development is carried out in mode of maintaining reservoir pressure at corresponding yearly volumes of injection and taking out liquid. Used as working agent is accompanying brine water with density of 1.04-1.14 g/cm3. EFFECT: high efficiency. |
