Downhole Oil Drilling Equipment Deep Well Pump Parts  

 In the rod-having pump operation ,API standard subsurface sucker rod pump is one quite important downhole oil production equipment ,which can be divided into tubing pump and rod pump.

Operating principle of tubing pumps:

The pump barrel assembly directly fixed on a tubing string .the plunger assembly connected on the sucker rod string, and with the up and down reciprocating motion, so as  to realize the production process. Its advantage lies in : in the process of oil production ,when the traveling valve and fixed valve side problems arise, valve side can be proposed by the sucker rod, piston and extractor, don't put the whole pump and tubing string out of the well, reduce the work intensity and the operation cost.

Operating principle of rod pumps:

Rod  pump is equipped with a supporting joint, support joint is connected on the tubing, rod pump plunger is connected on the sucker rod string, and is fixed on the supporting joint through the sucker rod string to the tubing, the plunger along with the sucker rod string's up and down reciprocating movement achieve pumping work. when pump appear quality problem, you needn't put forward tubing, only through the sucker rod pull the whole pump from the wel and operation is simple.
