涠洲12-1油田北块注水优化数值模拟研究

Study of numerical simulation for water injection optimization in north block,Weizhou 12-1 oilfield

涠洲12-1油田北块储层连通性复杂,非均质性较强,稳定注水开发存在原油产量低、采出程度低、稳产难度大等问题。为了提高该油田综合开发效果,为油田下一步开发调整提供依据,利用油藏数值模拟技术对该油田进行了注水方案研究。通过对比分析,优化的不稳定注水方案比常规注水方案原油采收率可提高3个百分点左右,为类似油藏的开发提供了借鉴。

In north block of Weizhou12-1 oilfield, because of it＇s serious heterogeneity and complex communication, oil production and recovery percent of reserves is low, and production stabilization is difficult with stable water injection. In order to improve it＇s development effect and provide evidence for future adjustment, eight water injection projects was studied by numerical simulation technique .and by comparing, the optimized water injection program can improve recovery efficiency 3 percent than general water injection program.
