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 oilield, because of it’s serious heterogeneity and complex communication, oil produc- tion and recovery percent of reserves is low, and production stabilization is dificult 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 eficiency 3 percent than general water injec- tion program.
