| description | The utility model relates to the field of oil exploitation equipment, in particular to an oil-well pump used for heavy oil steam stimulation. The oil-well pump used for the heavy oil steam stimulation comprises a pump body, an upper joint and a lower joint, the upper joint and the lower joint are used for connecting the pump body and the corresponding casing pipes, the pump body comprises a stator component and a rotor matched with the stator component, the rotor and the stator component together form a screw pump, the inner wall surface of the stator component is a metal wall surface, the rotor is a metal rotor, the upper joint is fixedly connected with the upper end of the stator component, and lower joint is fixedly connected with the lower end of the stator component. In the process of using, when steam injection is needed, the rotor only needs to be lifted, when oil pumping is needed, the rotor can be directly down for work, and the integration technology of heavy oil steam stimulation injection-production is achieved. The oil-well pump used for the heavy oil steam stimulation can be directly used in a thermal production well. |
