| 摘 要： | 通过对比分析电潜泵排水工艺实施前后天东90井排水幅度、井底流压下降速度及邻井水气比变化情况,评价了天东90井电潜泵排水实施效果。天东90井实施电潜泵排水后,排水量最高达到450m3/d,高于正举,反举,略高于增压正举排水,与增压反举措施排水量相当。同时,井底流压下降速度高于周边气井,说明实施电潜泵排水措施初见成效。

| Abstract: | By comparatively analyzing the changes in Tiandong 90 well, such as in drainage range, descending speed of bottom hole flowing pressure, and water-gas ratio, before and after implementation of ESP drainage technology, the drainage effect is ealuated. After ESP drainage, the maximum water discharge is up to 450m3/d, which is higher than that of the drainage with air flowin annular space or central tube, slightly higher than that of pressurized drainage with air flow in annular space, and equal to that ofpres... |
