水力喷射泵具有独特的抽油工艺特点，适用于稠油井、高凝油井、超深井、高矿化度以及特殊探井等。在稠油油藏开采中，利用单一水力喷射泵和“有杆泵+喷射泵”组合举升方式顺利将稠油举升到地面。现场生产数据表明，水力喷射泵能够实现深层稠油的顺利举升，组合方式还能使低液面井恢复生产，对低渗油藏具有明显的增产效果。

Hydraulic jet pump has a peculiar distinguishing feature in oil pumping technology. It fits for the heavy oil well, high pour pointcrude well, ultradeep well, high mineralization well and some particular exploration wells. The use of single hydraulic jet pump lifting and the combination lifting of beam pump and jet pump can lift the oil to surface successfully during the production of heavy oil. Field production data show that the hydraulic jet pump can lift the oil to surface successfully from deep heavy oil well. The combination lifting can not only recover the deliverability in low fluid level wells but also increase the producing capacity in low permeability reservoirs.
