优化控水技术在马寨油田的应用

Application of Optimization Water Control in Mazhai Oil Field

应用注水井、生产井的现有资料和优化控水技术基本程序 ,分析了产油井产水量高的原因 ,建立了调剖井的定量的筛选标准 ,对马寨油田生产井和注水井的调剖处理进行了排序和程序设计 ,对调剖技术和马寨油田近三年优化控水措施的结果进行了讨论和分析 .最优化控水技术的关键是评价注水井和油井的连通程度 .评价结果表明生产井和注水井之间存在很好的相关系数时 ,调剖后 ,生产井一般均受到好的影响 .

The causes of high aquifer yields of oil-producing wells in Mazhai Oilfield were analysed according to the sequence of optimization water control. The standard of selecting profile control wells was established. The profile controls of producing wells and water injection wells was ordered and designed. The results of optimization water control of Mazhai Oilfield in the last three years were analysed. The analysis shows that the key of optimization water control is the evaluation of the communication degree between water injection wells and producing wells, and when the correlation factor between them is greater, the result of water decrasing and oil increasing is obvious after profile control.
