基于大芦湖油田S342层开发生产状况和规律分析,应用Eclipse油藏数值模拟软件研究了大芦湖油田S342层剩余油分布状况。结合水平井方位和水平生产井段长度优化结果,设计了S342层开发调整方案,方案开发指标预测结果表明设计方案有利于减缓产量递减和控制含水上升速度,可提高采收率6.62个百分点,增加可采储量18.14×104t,具有良好经济效益。
Based on the analysis of the development and production of S342 layer in Daliu Oilfield, the remaining oil distribution in S342 layer of Daliu Lake oil field was studied by using Eclipse reservoir numerical simulation software. Combined with the horizontal well orientation and horizontal production well length optimization results, the S342 layer development and adjustment program was designed. The project development index prediction results show that the design scheme is conducive to slow down the production decline and control the water-bearing rising speed, which can increase the recovery ratio by 6.62% Recoverable reserves of 18.14 × 104t, with good economic benefits.
