Sucker rod pump for oilfield

Tubing Pump:

For tubing pump, the barrel is put in the well to the designed depth with tubing. And then put the plunger into the barrel with sucker rod. Given the tubing size, the bore of the tubing pump is larger than that of the rod pump, so the pump rate is higher. According to seating mode, the rod pump can be divided into three types: THC pump (Stationary Heavy Wall, Cup Seating, Tubing pump), THM pump (Stationary Heavy Wall Mech. Seating, Tubing Pump) and THD pump.

Rod pump:

Rod pump is also referred to as "insert pump" as its plunger is attached tok and moves up and down with the sucker rod string .It is suitable for reducing the time of work over for deep well as it is not necessary to pull all the tubing out of the well hole when checking the pump, which makes the operation quicker and the service life of tubing longer. The rod pump is in a state of "free hanging", so it is suitable for deviated wells. According to seating mode ,the rod pump can be divided into two types: cup hold-down and mechanical hold-down. According to anchored position, the pump can be divided into top hold-down pumps and bottom hold-down pumps which include stationary barrel and traveling barrel types.
