Abstract: This paper describes detailly a set of experimental device that has many modeling experiment function of well pump used in horizontal and directional well. This device can be used to test on pump operation situation in different working condition, such as used in vertical,horizontal and directional wells, structure type and size about pump valve,stroke loss modeling and separating sand device structure as well. The medoling experiment results of pump valve have shown that the pump valve combination of the mechanical opening and closing valve and cone valve has well pump efficient when the incline angle and liquid viscosity are less. Especally,the pump valve combination of the mechanical opening and closing valve and rod carrying valve has better efficient in the condition of horizontal well.
