分层注水是解决油田开发过程中的层间矛盾,实现有效注水,保持地层能量,维持油田长期稳产、高产,提高水驱动用储量和采收率的重要手段。而分层注水有效率的高低主要取决于分层注水有效期的长短。分析了胡庆油田分层注水井分层注水失效的原因,并提出了具体的解决办法。

Separate layer water injection is an important way to solve interlayer interference of oilfield development keep formation energy ,maintain production level of the oilfield , improve water flooding reserves and recovery efficiency. And the discretion of water zone flooding efficient mostly lie on period of validity. This paper analyze water zone flooding disabled reason of Huqing Oilfield and propose the specific solve way.
