Special pumps for Inclined wells

Inclined well pump with forced shut-down solves the problem that the pump efficiency of conventional tubing pump is greatly reduced when pumping in inclined well. It is suitable for oil production in inclined well  where the inclination angle of the well is within 45 °.

 

Due to the increase of horizontal wells, side-drilling wells and cluster wells, downhole pumps are sometimes required to work in the inclined well section, which is prone to have the following problems:

  1. Eccentric abrasion of Plunger;
  2. The valves cannot be returned in time, resulting in inadequate sealing or even sealing failure;
  3. Low pumping efficiency.

The experiments show that the valve balls cannot be sealed at a level  within 75°, which requires a ball sucker to attract the valve ball to seal; at a level within 45°, the valve ball cannot be sealed in time, and it takes 1 to 6 seconds to seal

To solve above problems,we developed special pumps for Inclined wells

Inclined well pump with forced shut-down solves the problem that the pump efficiency of conventional tubing pump is greatly reduced when pumping in inclined well. It is suitable for oil production in inclined well  where the inclination angle of the well is within 45 °.

 

Characteristics

  1. The special structure of traveling valve and standing valve can force the valve ball to fall back timely and accurately.
  2. Rotary plunger that rotates automatically while working can prevent the plunger from being lopsided worn.

Application

  1. Apply to the oil well with high gas cut.
  2. Degree of inclination of oil well<45°
