摘　　要：在对双河油田Ⅳ1-3层系特高含水期剩余油分布规律及影响因素分析的基础上,提出以井网综合调整、优化注水产液结构调整为核心的稳油控水先导试验方案,使该单元的开发效果得到明显改善,采收率提高2.85个百分点,可采储量增加36.6×104t。先导试验的成果和经验对老油田特高含水期稳油控水有借鉴作用。A pilot program of production stabilization and water-cut control with comprehensive well pattern modification and optimization of fluid production as its core was drawn based on analysis of residual oil distribution pattern and its influential factors at ultra-high water-cut stage inⅣ1-3strata series in Shuanghe oilfield.This pilot remarkably im-proved development efficiency of the unit yielding a recov-ery factor of 2.85%higher than that before and incremental recoverable reserves of 36.6×10 4 t.The pilot results and experiences achieved can be used for reference in produc-tion stabilization and water-cut control at ultra-high water-cut stage in old oilfields.
