The invention discloses a safety lifting monitoring system and method for a downhole pump. The conception of the safety lifting monitoring system is that a weight sensing mechanism is arranged on a mounting bracket or a body of electric lifting equipment, the pull-down force in the lifting process of the downhole pump is monitored in real time, whether clamping happens or not can be judged according to the measured value of the pull-down force, particularly, in the process of lifting the downhole pump, once scratching and friction occur, the changing pull-down force numerical value can be sensed in time, and corresponding control decisions such as reminding an operator to pay attention, switching to manual operation or stopping lifting operation can be made according to the sensed changing pull-down force numerical value. The system can check erroneous ideas at the outset for the lifting operation of the downhole pump, discovers abnormal conditions in time, effectively avoids the damage probability of equipment, and greatly reduces the safety risk.

    本发明公开了一种用于井下泵的安全提升监控系统及方法,本发明的构思在于在电动起重设备的安装支架上或其本体上设置重量感应机制,实时监测井下泵提升过程中的下拉力,并可以根据该下拉力实测值判断是否发生了卡顿,具体地,在提升井下泵的过程中一旦发生剐蹭、摩擦,便会及时感应到变化的下拉力数值,而根据该感应到变化的下拉力数值,可以做出相应的控制决策,例如提示操作人员注意、切换为手动操作或者中止提升操作等。本发明可以对井下泵的提升操作起到防微杜渐的作用,及时发现异常情况,有效避免了设备损坏几率且大幅降低了安全风险。
