本文论述了增压泵的结构、工作原理及增压泵与普通泵在中后期抽油时,由于增压泵靠自身能量转化帮助进油,摆脱了依赖或较少依赖沉没压力进油的工况,油井动压随之降低,根据IPR曲线,油井有不同的动压,就有不同的产量。因此可使油井增产,抽油泵效提高。现场试验也说明了,增压泵能较普通泵在较低沉没度下正常抽油。在相同工况下,增压泵较普通泵充满程度高。因而增压泵在中后期抽油井有着广泛的应用前景。
This article discusses the structure of the booster pump, working principle and the booster pump and ordinary pump in the mid-late pumping, because booster pump to help their own energy into the oil, get rid of rely on or less dependent on sunken pressure into the oil In the meantime, the dynamic pressure of the oil well decreases. According to the IPR curve, the oil well has different dynamic pressures and different yields. Therefore, oil wells can increase oil pumping efficiency. Field test also shows that the booster pump can pump oil at lower submergence than normal pumps. Under the same conditions, the booster pump is more full than ordinary pump. Thus booster pump in the late pumping wells have a wide range of applications.
