中排气双柱塞防气抽油泵
简 介:
中排气双柱塞防气抽油泵泵筒中部开有进油排气槽,该槽具有进油排气作用,可大幅度提高泵的充满系数,防止气锁。使用此泵时,井下可不配泄油器,也可不动管柱进行注汽热采。故该泵适用于含气井或稠油井。
The are several slots around the middle of the barrel.When the plunger is in the uppermost position,the slots possess the function of oil entering and gas escaping.This can increase the filling coefficient and prevent “gas-lock“.It is not necessary to install the oil drainers in down-hole and the vapour-injection operation can be done without lifting the tubing strings.So the pump is suitable for the heavy crude oil wells and gaseous wells.
