液压反馈式抽稠油泵
简 介:
液压反馈式抽稠油泵工作时具有液压反馈力,可帮助柱塞下行,特别适用于稠油井生产。原油粘度4000厘泊以下时可不用降粘直接抽汲。该泵无固定阀,井下可不用泄油器,还可不动管柱进行井下测试和注汽热采。
The pump moves with the help of the feed-back force when the pump is operating so the pump is very suitable for sucking heavy crude oil.The pump can work smoothly in a heavy crude oil with the viscosity smaller than 4000 centipoise. There is no standing valve in the pump.It is not necessary to install the oil drainers in down-hole and the well-testing and vapour injection operation can be done without lifting the tubing strings.
