摘　　要：目前海上油田主要以电潜泵为主要的机采手段,但是在稠油油田,电潜泵存在着泵效低的问题,并且对于超稠油电潜泵无法使用。但是目前电潜螺杆泵在海上的应用,主要受限制于排量低的制约,仅能在产量较低的井中应用;并且在海上实际使用的电潜螺杆泵中,实际使用寿命均较短,不能满足海上油田大排量、长寿命的要求。探讨了对电潜螺杆泵泵型、联轴器、减速器等主要部件进行改进,开发出了排量达到200 m^3/d,实际使用寿命超过一年的电潜螺杆泵,并在海上油田成功应用,取得了较好的效果。electric submersible pump as the main method of Mechanical recovery in the offshore oilfield , but in the heavy oil fields, there is the problem of the low efficiency of the electric submersible pump and electric submersible pumps can not be used for super heavy oil. The application of Electric submersible pump in the offshore oilfield is limited by the displacement, only in a lower yield of well applications, and in the actual use of the electric submersible sea screw pump, the actual service life are shorter, can not meet the high flow rate and the long-life requirements. The main components of the electric submersible pump-type screw pump, coupling, reducer improvements developed displacement to 200 cubic meter / day, the actual life of more than one year of electric submersible screw pump, and in the success of the offshore oil field application, and achieved good results.
