美国Ｃｅｎｔｒｉｌｉｆｔ公司开发的ＫＣ２００００型水平井采油电动潜油离心泵，可在３５００ｒ／ｍｉｎ高转速条件下正常抽油。其外径为１４３ｍｍ，在水平井中采液能力为４８００ｍ３／ｄ，离心泵每级压头为１５ｍ，泵效可达７０％，相当于大型电潜泵的泵效。常规电潜泵需
Centrilift company developed by the United States KC20000 horizontal well production of electric submersible centrifugal pumps, high speed conditions in the 3500r / min normal oil pumping. Its outer diameter is 143mm, the horizontal well liquid production capacity of 4800m3 / d, centrifugal pump each stage of 15m, pump up to 70%, equivalent to large-scale electric submersible pump pump. Conventional electric submersible pump needs
