摘　　要：在压力恢复试井解释过程中,生产时间对压力导数曲线后期形态有着十分重大的影响,会直接影响解释模型的选择和径向流阶段的判断。文章从压力恢复试井压力导数提取方法出发,说明生产时间是如何影响压力导数曲线形态的,在此基础上提出生产时间的合理取值方法。The production time,which has a signif icant influence on the late part of pressure derivative curve in a build-up well testing interpretation,will affect the choice of interpretation model and inf inite act radial flow.This article illustrates how the production time is affecting the behavior of pressure derivative curve according to the pressure derivative extraction method.On this basis,we recommend the proper method of inputting a reasonable production time.

关 键 词：压力恢复试井 压力导数曲线 生产时间
