摘要
螺杆泵井生产运行时,沉没度过低会造成转子在定子中干磨,使定子脱胶,造成螺杆泵损坏,利用螺杆泵井防抽空配套技术可使螺杆泵井举升设备处于良好工作的状况。该配套技术能自动监测并控制机采井动液面,实时调整转速,实现了螺杆泵井的智能调参,使螺杆泵井运行过程中保持稳定合理的沉没度。螺杆泵井防抽空配套技术在现场试验应用10口井,平均单井沉没度恢复了61m,百米吨液耗电降低了0.28k W·h,系统效率提高了2.79%,有效地避免了4口沉没度小于100m螺杆泵井的抽空。现场试验表明,该配套技术能避免出现螺杆泵井的抽空现象,延长螺杆泵的检泵周期。
When screw pump is put into production, low submergence would cause the rotor worn in the stator, resulting in the rubber falling off the stator to damage the screw pump. The technology for preventing evacuation in screw pump wells can keep the lifting equipment in screw pump wells working under good condition, which can monitor and control the dynamic fluid level of pumping production wells automatically; adjust the rotary speed in real time; and realize the intelligent adjustment of parameters in screw pump wells, so as to keep stable and reasonable submergence while running the screw pump. The matching technology for preventing evacuation has been used in 10 screw pump wells in the field application, average submergence was recovered by 61 meters per well; electric power consumption for one ton liquid to lift 100 meters was reduced by 0. 28 k W·h; system efficiency increased by2. 79%, which effectively avoided the evacuation in four wells with the submergence being less than 100 meters in the screw pump wells. Field test showed that the matching technology could avoid the evacuation in screw pump wells, and have prolonged the screw pump maintenance cycle.
