Abstract: this paper has introduced three kinds of rod pump used in thick oil horizinal well: the rod pump with hydraulic balance cylinder,the rod pum,p with suction valve of guide function and the rod pump with armular valve. Ac-cording to review the principle of work and characteristic of the rod pumps,writer has studied the leaking calcalat-ing method of the annulus clearance of rod pump used in horizontal well. Through anaylsing the field experiment,it is explained that the new made for horizontal wells have good property: smooth and steady,dependable and ef-fective and it can be applied in heavy oil wells very well.the efficiency of pump reached above 41-43%.

Key words: Horizontal well, Rod pump, Fluid leaked volume, Heavy oil
