产品描述

简    介:

 

    环流式抽稠油泵是反馈型抽稠油泵的改进型,保留了原油的优点,并将进油阀改为环流阀,增大了过留面积,缩短了进油流程,从而减小了进油阻力。同时下泵采用短泵筒长柱塞,能有效地避免砂卡现象。该泵适用于7” 套管井,φ57/φ38 泵也可用于5 1/2” 套管井。

 

    The pump is a improved type of the hydraulic feed-back pump for heavy crude oil.Not only the former advantages have been remained but the inflow valve has been changed to be a annular valve in this kind of pumpwhich obtains a large flow area and shortens the inflow tubing so the inflow resistance is decreased .In the meantime for using a long plunger and a short barrel in lower pumpthe phenomenon of sand-up can be efficiently avoided .The pump is suitable for 7” casing wellthe pumpφ57/φ38 may be used in 5 1/2”casing well.
