    • A method for operating a progressive cavity pump in a borehole comprising mounting a stator to a tubing string and inserting the stator and tubing string into a borehole wherein the stator has at least first and second active stator sections that are at different locations on the stator, then performing a first operating phase involving inserting a first rotor into the tubing string until the first rotor is located at a selected downhole position, wherein the first rotor has a first active rotor section that is aligned with the first active stator section when the first rotor is in the selected downhole position, and rotating the first rotor relative to the stator such that the aligned first active rotor and stator sections generate a pumping force. The method also comprises a second operating phase involving removing the first rotor from the borehole, and inserting a second rotor into the tubing string until the second rotor is located at a selected downhole position, wherein the second rotor has a second active rotor section that is aligned with the second active stator section when the second rotor is in the selected downhole location, and rotating the second rotor relative to the stator such that the aligned second active rotor and stator sections generate a pumping force.
    • 一种用于在钻孔中操作渐进腔泵的方法,包括将定子安装到油管柱上并将定子和油管柱插入钻孔中,其中定子具有位于定子上的不同位置的至少第一和第二有源定子部分, 然后执行第一操作阶段,包括将第一转子插入管柱直到第一转子位于所选择的井下位置,其中第一转子具有第一有效转子部分,当第一转子 处于所选择的井下位置,并且使第一转子相对于定子旋转,使得对准的第一主动转子和定子部分产生泵送力。 该方法还包括第二操作阶段,包括从钻孔中移除第一转子,以及将第二转子插入管柱中,直到第二转子位于选定的井下位置,其中第二转子具有第二主动转子部分, 当所述第二转子处于所选择的井下位置时,与所述第二有源定子部分对齐,并且使所述第二转子相对于所述定子旋转,使得所述对准的第二主动转子和定子部分产生泵送力。
