摘　　要：乌南油田自1998年在乌4-5井间歇试注水,2002年在乌4断块开展规模试注水。虽然该油田已注水开发近10年,但该注水开发效果不是很理想,油井见效缓慢、稳产效果差。本文根据乌南油田近些年的动静态资料,提出几个影响该油田注水开发效果的地质因素,为油田确定合理的水井措施、注采井网的局部调整提供依据。Wunan oilfield has started intermittent water injection in 4-5 wells since 1998, in 2002, started scale type of water injection Wu NO.4 . fault block. Although the oilfield has taken waterflooding development for about 10 years, the effect of waterflooding development is not ideal, whichwell has a slow effect show and stable effect . This paper, based on the dynamic and static data of Wunan oilfield in recent years, puts forward severalgeological factors affecting the water-injection development effect, and provide reference for determining reasonable wells measures and the localadjustment of injection-production pattern.
