利用压裂与水力泵联作管柱试井工艺初探

Research on Using Fracturing and Hydraulic Pump League as Well Test Technology

通过在水力泵泵芯下方增加关井装置,实现水力泵排液后井下关井。在排液期间,可尽最大可能扩大波及范围,使压力反映井周更大范围信息,录取压力恢复数据资料,达到测试目的。利用压裂—水力泵联作管柱进行压力恢复试井,使水力泵的使用进入了一个新的发展阶段。

Through hydraulic pump in core below increase shut-in device,we realized underground shut-in after hydraulic pump liquor drainage.In the drainage period,the scope affected should be expanded as greatly as possible to make the pressure reflect more range information around the well.Then the pressure recovery data were recorded and the testing purpose was achieved.Using fracturing and hydraulic pump league,the pressure recovery well test was carried out and the use of hydraulic pump achieved a new stage of development.
