Special pumps for corrosive oil wells

we adopt conventional sucker rod pumps for oil recovery, normally we will get a very low pump efficiency. Meanwhile, gas locking may happen frequently, which will bring a lot of trouble to oil recovery and make us lose countless time and money for repairing the pumps.

The anti-blocking pump is designed to solve the problem of falling objects blocking the pump.

The principle of this pump is same with ordinary pumps. It only adds the sand-fixing anti-burial standing valve which effectively solves the problems of sedimentation of tubing and rod that block the standing valve. Therefore, the oil well can be produced normally and a lot of post-production work is avoided. It reduces the pump inspection peroid and extends the maintenance-free period.

Piston ring type insert pump Features

1)The piston ring is always close to the inner wall of the barrel which increases the sealing performance.

2)The piston ring has an automatic compensation function which can extend the high efficiency period of pump.

3)There are sand scraping devices at both ends of the plunger which can scrape the sand particles on inner barrel and those particles are carried away by flow liquid. Then extend the service life of pump.

Application

Suitable for oil well without sand.

Rotation-Plunger sucker rod pump Features

1)Add a rotator on an ordinary pump which not only has a rotation function, but also has a function of anti-dropping.

2)The rotary plunger is used to automatically rotate under the action of oil flow.

Application

Suitable for oil wells which are worn due to non-inclined well factors.
