分阶段数值模拟在八面河油田面4区剩余油研究中的应用

Application of Numerical Simulation by Stages in Remaining Oil Research for Mian 4 Block of Bamianhe Oilfield

八面河油田面四区是以常规注水方式开发的稠油油藏,目前处于特高含水开发阶段,剩余油分布零散,严重影响了开发效果。为了精确描述该油藏的剩余油分布特征,本文通过建立不同开发时期的地质模型选用分阶段油藏数值模拟的方法来研究剩余油。研究结果表明,分阶段建立地质模型进行模拟,其模拟结果更符合油田开发实际情况,其研究结果可以为下步的开发调整作有利的指导。

There are a heavy oil reservoir developed by water flooding,which is in the extra high water cut phase,the remaining oil distributed discontinue,which impact the development emotion.To describe the remaining oil distribute character accurately,the method of multi-stages simulation technique for dif- ferent development phase model was used in the research of the mian 4 block of the Bamianhe oilfield.The result of the research approved:the result of the multi-stages simulation for different phase accord with ...
