| 摘 要： | 根据常规的摩阻计算方法，结合目前油田压裂现状，在压裂施工时进行停泵和几个排量改变，求取相应参数，形成一套行之有效的区分射孔孔眼和邻近井筒摩阻的方法。并用计算结果推断摩阻产生的原因，制订相应的解决办法，现场应用效果较好。

| Abstract: | Near-wellbore friction and perforation friction are distinguished by using conventional friction calculation method and current fracturing status.Pump-off and discharge change are conducted during fracturing operation in order to solve corresponding parameters.The calculation result is used to deduce the reason of friction,and corresponding solutions are worked out.Field application has shown good result. |
