榆树林油田水井钻关的几点认识

Views about Shut-in Injection Well in Yushulin Oilfield

文章针对榆树林油田加密区水井钻关状况进行分类分析,得出了不同钻关时间内钻关区产量递减趋势:钻关时间3个月以内,区块开发状况基本保持稳定;钻关三个月后,产量有所下降,且随着钻关时间的增加,递减幅度增大。同时根据钻关区特点提出几点建议,为今后控制钻关区产量递减提供指导。

In this article, we classify the injection wells in the infull well pattern area, and then get the trend of the production in the control pressure region for drilling： within three months, the situation keeps stable; after three months, the oil yield begins to decline, and as the time elapse, decreasing rate get faster. And then, according to the characteristics of the drilling area, we raise some advises, for guiding how to control the yield decline.
