抽油井强制增液装置的研制与应用

Research and application of constraint liquid increasing unit for punping well

针对深层低渗油层能量较低的抽油机井研制了可以在低沉没度下工作的抽油井强制增液装置。研究及应用表明 ,由于其动力活塞的作用 ,使抽油机上冲程活塞两端压差降低 ,解决了气体影响抽油泵泵效的难题。其可在低沉没度下工作的特点 ,使其在一定范围内上提泵挂成为可能 ,从而减小了抽油机的冲程损失 ,提高了系统效率 ,降低了能耗。此外 ,由于抽油井强制增液装置增大了进油流道的截面积 ,使得摩擦损失大为降低。

Research and application show that the constraint liquid increasing unit can reduce stroke loss of pumping unit,which increases the efficiency of system and reduce energy consumption.For the sectional area of oil flowing path is enlarged,the friction loss is reduced to a great extent.
