摘　　要：缩短抽油井测压时间 ,可通过校正续流来进行。对应用Duhamel原理得出的卷积积分提出了显式解。用该解解释早期段测试数据 ,能消除续流影响 ,加快压力恢复速度达到缩短测试时间的目的。同时 。Reducing the measuring time in a pumping well would be implemented through calibrating afterflow. An explicit solution is proposed for the convolution integral obtained with Duhamels principle. The influence of afterflow would be eliminated to expedite pressure buildup for the purpose of shortening the measuring time by interpreting the data obtained at early stage with the solution . At the same time, the contradiction of deriving formation pressure that could not be interpreted at early stage by using the other method is eliminated.
