八面河南区高含水期开发技术政策研究

On Development Technical Policy of Southern Ba Mianhe Oil Field in High Water Cut Phase

八面河油田南区目前进入了特高含水开发阶段,层间差异日益严重,剩余油分布零散,井网适应性逐年变差,影响整个油藏开发经济效益的提升。针对这些问题,综合应用油藏动态分析、物理模拟、数值模拟等方法,对南区开发进行技术政策研究,确定了油田高含水期层系细分的原则,同时在综合研究的基础上,对以面五块为重点的南区进行层系调整、井网重组研究,编制南区综合调整方案和面五块开发调整方案,取得了较好开发效果。

the development of the southern part of Ba Mianhe Oil Field is disturbed by ultrahigh water cut, the economic efficiency of the whole reservoir development has been affected due to the increasing differences between layers, sporadic remaining oil and the degrading well net adaptability. To address these problems, this paper conducted a technical and policy research into the development of the southern area by adopting a combination of various methods such as reservoir dynamic analysis, physical simulation and numerical simulation thus determining the principle of finely breaking down the layers in high water cut oil field. Meanwhile the paper outlined the adjustment plans for the southern area and the Mian 5 Block which is the focus of the southern part to rearrange the layers and well networks towards a better development effect.
