It is suitable for corrosion and small amount of sand and gas, deep Wells, such as complex well conditions, the use of safe, stable performance and wide application.
Under operation easy to operate, economical and practical, it can reduce oil field operation cost by more than 30%.
It can be designed according to the customer’s well.
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 problem,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
