针对不同区块注入压力差别大的情况,注水泵出现大马拉小车现象,对注水系统能耗损失较大,合理划分注水管网,分区注水,减少节流损失;高压注水压力界定受多方面因素制约,本文分析了如何科学合理地确定注入压力,分区分压技术应用进入现场试验、应用,取得了显著增注效果,提高注水系统效率,降低注水单耗,降低注水系统运行成本提供可借鉴的思路和模式。 In view of the large difference in injection pressure in different blocks, the phenomenon of big horse-drawn car in water injection pump causes large energy loss to the water injection system, which reasonably divides the water injection pipe network and district water injection to reduce the throttling loss. The definition of high-pressure water injection pressure depends on many aspects This article analyzes how to determine the injection pressure scientifically and rationally, apply the partial pressure dividing technology into the field test and application, and obtain significant re-injection effect, improve the efficiency of water injection system, reduce the unit consumption of water injection, and reduce the operating cost of water injection system. The ideas and patterns.
