Cup Or Mechanical Seating tubing Type Downhole Pumps
Cup or mechanical seating tubing type downhole pumps Description
Tubing pump barrel is connected to the tubing is directly run into the well at desired depth and then the plunger is run into the barrel with the sucker rod. The applicable tubing pump is larger in size than rod pump in the same tubing.
Tubing pump has simple structure so the displacement is bigger and it is suitable for the shallower well with shallow depth and high production.
In the process of production, when traveling valve and standing valve appear problems,we can pull the traveling valve and standing valve out the well through the sucker rod string, plungerand the puller ,instead of pull the whole pump and tubing string out of the well, reduce the labor intensity of operation, reduce the operation cost.
