摘　　要：双河油田V上层系是河南油田第一个二类储量高温聚合物驱先导试验区块,通过采取优化聚驱井网,提高井网控制程度;利用油藏数值模拟方法优化聚合物注入参数;注入聚合物前调剖封堵大孔道;见效油井及时提液等对策,使该区块日产油由注聚前125t增至182t,综合含水降低了3.3个百分点,阶段累积增油2.35×104t,聚合物驱阶段开发取得了明显的降水增油效果,形成了一套提高二类储量高温聚合物驱效果的作法,对二类储量聚合物驱推广应用有借鉴意义。V formation is the first Pilot test unit of class II reserves with high temperature polymer flooding in Henan oilfield.In this paper,perfected polymer flooding well-net and enhancing well-net controlling extent is put forward,using reservoir numerical simulation to optimize injection parameters,adjusting profile control to block the larger reservoir channels before injecting polymer,and instantly enhancing production of effective oil well.Obvious effect of increasing oil and decreasing water production is achieved:daily oil output increased from 105t before polymer flooding to 182t,and average water-cut lowed 3.3% with total additional oil 23,500t.A set of technologies to enhance effect of class II reserves with high temperature polymer flooding is formed.It provides a referential evidence for development of class II reserves with high temperature polymer flooding.
