Abstract: The present invention relates to a plug and valve integrated cone valve pump with combined type movable and fixed three cylinders and two spiral centralizers, which is applied to suction working conditions in highly deviated well sections. It comprises three pump cylinders, which are combined type including two fixed cylinders and a dynamic cylinder, two centralizers, which are combined type including a dynamic spiral centralizer and fixed spiral centralizer, a fixed cone valve, a cylinder and plug integrated springing fixed cone valve, a fixed plunger and a movable guide rod cone valve to solve the problems such as stuck pump, eccentric wear between plunger and pump cylinder and valve leakage.

Abstract: The three-stage axial flow degassing device adopts an efficient degassing technology including a vertical high speed swirling field, a horizontal rapid axial flow field and a vertical reversing scrubbing field formed by a combination of vertical tubes; the first-stage degasser performs the first-stage segmental vertical high speed swirling degassing operation, removes the gas phase carried by the gas-containing fluid, and forms a primary gas and a primary fluid; the microporous uniform mixer breaks bubbles of the primary fluid and forms a gas-liquid uniform mixed flow; the second-stage degasser performs the second-stage horizontal vane wheel swirling generating rapid axial flow degassing operation, removes the gas phase carried by the gas-liquid uniform mixed flow, and forms a secondary gas and a secondary fluid; the third-stage degasser performs the third-stage vertical reversing deep degassing operation, removes liquid phase carried by the secondary gas, and forms a tertiary gas and a tertiary fluid.
