该油藏构造复杂,断块小、含油层位多。针对在注水开发存在注采井距小、压降快、注水见水快、水驱采收率低、注采井网调整余地小的状况,制定了先注后采、以吸水指示曲线分层测试资料为指导的周期注水、逐层注水等注水开发政策,有效控制含水上升速度,延长稳产期,提高水驱油效率。 The reservoir is complex in structure with small fault blocks and many oil-bearing beds. Aiming at the situation that there is a small injection well spacing, rapid pressure drop, quick water injection, low waterflood recovery rate and small adjustment of injection well and well pattern in waterflooding development, Test data as the guidance of the cycle of water injection, water injection and other water injection development policies to effectively control the rate of rise of water to extend the long-term stability and improve water flooding efficiency.
