摘要
研究不同关井前生产时间对双对数坐标系中压差及压力导数曲线形态的影响,利用试井软件Saphir中的压降导数曲线和压力恢复导数曲线的对比功能,最终确定满足测试要求的关井前生产时间。
In order to find out appropriate producing time before shutting-in a well which means that the curve shape will not be influenced seriously for build-up test,we use the comparison function of the drawdown derivative curve and build-up derivative curve in Saphir.This method can effectively reduce the complexity of well testing.
