摘要
涠洲 11 4油田目前已处于开发后期 ,实施换大泵提液、开发油田东区和高含水井侧钻等措施 ,其增产效果不够理想。为此 ,以涠洲 11 4油田生产历史数据为基础 ,通过对国内外大量文献资料的调研 ,选择常规黑油模型ECLIPSE10 0对多个非混相驱注入方案 (包括注入流体类型、注入部位、注入量等 )进行了数值模拟研究 ,认为利用该油田具有输气管线现成、气源又有保证的有利条件 ,实施油层上部注水下部注气 ,可经济、有效地提高该油田的采收率。
Weizhou 11*.4 oilfield has been in late phase of development, and several measures are not desirable to increase production, such as installing larger pumps, developing the east block of the field and sidetrack in high water-cut wells. Based on the production history data of Weizhou 11*.4 oilfield and an investigation on literatures in China and abroad, the ECLIPSE100 software,a black oil model simulator,is used to make numerical simulation for several immiscible gas injection schemes. The simulation results indicate that water injection in upper pay and gas injection in lower pay can improve oil recovery economically and effectively by making use of the existed gas pipelines and ensured gas source in the field.
