潜油电泵因其高排量,使原油增产、上产效果明显,在塔里木油田得到广泛的应用,但由于潜油电泵机组外径大、结构复杂,一旦被卡或落入井内,处理非常困难。东河1-5-9井用近5个月时间的探索和施工把落入井内机组成功打捞出井,为以后超深井电泵打捞积累了宝贵的经验。 Due to its high displacement, the submersible pump has been widely used in the Tarim Oilfield because of its high displacement and high production efficiency. However, due to its large outer diameter and complex structure, the submersible pump has once been stuck or dropped into the well, very difficult. 1-5-5 wells of Donghe River have successfully salvaged the units that fell into the well with the exploration and construction of nearly 5 months, thus accumulating valuable experiences for the ultra-deep well pump-recovery.
