通过实例,详细介绍了智能间抽装置在油井产量递减时引起的供液不足、油井液面低于泵吸入口深度而导致的抽油机运转效率降低、增大抽油泵空抽磨损、降低抽油泵的使用寿命的难题,根据油井的供液情况制定抽油机的生产工作时间,手动控制抽油机的启停。实践证明,在确保油井产液量基本稳定的前提下,根据油井动液面即沉没度的大小,油井实施智能间抽,不仅大幅度减少无功损耗,油井泵效及系统效率有了明显提高,实现了油井生产的最优化运行,节能效果显著。
Through examples, the paper introduces the shortage of liquid supply due to the decrease of oil well production when the smart pumping device is introduced in detail. When the oil level is lower than the suction depth of the pump, the operating efficiency of the pumping unit is reduced, the air pumping wear of the pumping pump is increased, Pump life problems, according to the situation for the well to draw oil pumping work production time, manual control pumping unit start and stop. Practice has proved that under the premise of ensuring that the oil well fluid production is basically stable, according to the size of the submerged liquid level of the oil well, the oil well implementation of intelligent pumping, not only significantly reduce reactive power loss, oil well pump efficiency and system efficiency has been significantly improved, Achieved the optimal operation of oil well production, energy-saving effect is remarkable.
