摘要
盘40断块馆三7油藏为典型的边底水油藏,水体锥进严重,直井开发效果差,目前处于低采出程度、低采油速度的开发阶段。针对断块存在的底水锥进严重的主要问题,利用后期新钻井、饱和度测井、数值模拟技术,分析水驱油规律及剩余油分布,研究边底水锥进特征,在此基础上设计了15口水平井,已投产7口,初期单井平均日油能力13.7t,含水14%,阶段产油7439t,取得了良好的初步成果。
Reservoir Ng37 in Block Pan 40 was a typical reservoir with edge and bottom water,where water coning was severe,the effect was poor in vertical well production,it was at the stage of low recovery percent and low oil recovery rate.In consideration of the problem stated above,analyses on production performance data and reservoir numerical simulation were conducted.Residual oil is studied.The causes and scale of water coning are clarified.On the basis stated above,15 horizontal well are designed,of which 5 wells are in production,initial single well production rate is 14 t/d with water content of 9%,good preliminary result is achieved.
