Downhole pump and rods oil and gas adopts a double plunger mechanical valve structure, which is suitable for the cold production of heavy oil with a viscosity below 4000mPa • S and the production of oil wells with higher gas content.

It solves the problem of slow opening and closing of traveling valves in heavy oil wells and gas-containing wells, improves pump efficiency and extends pump service life.

The double plunger injection-production pump is suitable for single-well steam huff and puff heavy oil thermal recovery.

Features:

1.The special structure can prevent barrel from scaling and damage after steam injection, and can prevent falling objects from entering the pump cavity.

2.Special structure prevents damage to the casing by steam injection.

3.The bottom of plunger is adopts a special structure to prevent the high temperature and high pressure in the tubing string from damaging the plunger.

Application

Suitable for single well that requires steam injection for thermal recovery.

The operation is simple and fast, and one string operation can realize two major steps of steam injection and oil recovery
Downhole oil pump is simple and fast in injection and extraction conversion, and the steam injection operation can be carried out when the plunger is lowered to the bottom, After the steam injection is closed, the plunger can be lifted to achieve pumping.
