Способ разработки нефтяной залежи относится к нефтяной промышленности и может найти применение при захоронении попутной воды и промстоков, образующихся при разработке и эксплуатации нефтяных месторождений. Цель изобретения - исключение возможности воздействия промстоков на продуктивные горизонты и объекты водоснабжения. В качестве поглощающего горизонта используют пласт, содержащий пластовую воду, сходную по минералогическому составу с промстоками, и расположенный ниже криогенного водоупора и выше многопластового горизонта с чередующимися песчаными и глинистыми прослоями. Начальное давление закачки промстоков поддерживают не ниже давления раскрытия природных трещин, имеющихся в поглощающем горизонте, закачку промстоков проводят на начальном этапе до достижения прироста пластового давления для скважин в системе нагнетания не более, чем в 1,4 раза, а на конечном этапе - не более, чем в 2,1 раза.The way to develop oil deposits relates to the oil industry and can be used in the disposal of associated water and industrial wastes generated during the development and exploitation of oil fields. The purpose of the invention is the elimination of the possibility of industrial waste impact on productive horizons and water supply facilities. As an absorbing horizon, a reservoir containing a reservoir water, similar in mineralogical composition with sewage, and located below the cryogenic sub-zone and above the multi-layer horizon with alternating sand and clay interlayers, is used. The initial injection pressure of industrial effluent is maintained not lower than the pressure of opening of natural cracks existing in the absorbing horizon; industrial effluent injection is carried out at the initial stage until the formation pressure increase for the wells in the injection system is not more than 1.4 times, and at the final stage - no more than 2.1 times.
