稀油油藏细分注水的特点及其应用

Characteristics and Application of Submerged Water Injection in Thin Oil Reservoirs

稀油油藏注水是通过注水井将水注入油层中,以确保油层压力,而细分注水是通过控制无效注水,提高储存层的能动程度来完成开采任务的。基于此,对稀油油藏细分注水的特点进行分析,从油田稳产、水量分配、油田开采等方面入手,详细地论述了稀油油藏细分注水的具体应用。

Water injection in thin oil reservoirs is to inject water into the oil layer through the injection well to ensure the pressure of the reservoir.Subdivided water injection is accomplished by controlling the ineffective water injection and increasing the activation level of the storage layer.Based on this,this paper analyzes the characteristics of submerged water injection in thin oil reservoirs,starting from the aspects of stable oil production,water distribution and oilfield exploitation,and discusses in detail the specific application of submerged water injection in thin oil reservoirs.
