The utility model relates to a long-distance hydraulic oil reciprocating pump. A bushing short connector, a pump head, a piston cylinder and a hydraulic cylinder are connected with the lower end of the shaft oil pipe in turn; the outlet of the hydraulic cylinder is blocked by a cylinder cover, on which a hydraulic pipe connector is mounted; a reciprocating hydraulic pump is mounted at the ground well mouth; a hydraulic pipe connected with the outlet of the hydraulic pump enters into the shaft to the bottom and is connected with the hydraulic pipe connector on the cylinder cover; a piston is mounted inside of the hydraulic cylinder; a plunger connected with axes of the piston extends into the plunger cylinder, which inner chamber communicates with the inner chamber of the pump head; a single ball valve is mounted on the pump head, which communicates with the pump outlet; a single valve is mounted at the pump inlet; and the ball valve chamber communicates with the inner chamber of the pump head through path. The long-distance hydraulic oil reciprocating pump of the utility model has the advantages of reasonable design, simple structure, reliable mechanical performance, low failure rate, small unit volume so as to reduce the field occupation, saving energy, safety, high efficiency and low cost.
Description
Technical field
The utility model belongs to pump, particularly a kind of long-range hydraulic reciprocating pump pumping unit.
Background technique
Traditional well recovery pumping unit is to drive the reciprocal tractive sucker rod of lever by motor by rocker-arm link to constitute, and is commonly called as the machine of kowtowing.This equipment is widely used in the oil recovery field, technology maturation, and its structural principle does not have to change substantially for a long time.This and the relative development of mechanical ﹠ electrical technology at present generally adopt today of new high-tech technical development incompatible, and its deficiency manifests gradually, as existing mechanical equipment is very huge, cost is high, rate of fault is high, energy consumption is big etc.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of long-range hydraulic reciprocating pump pumping unit is provided.
Long-range hydraulic reciprocating pump pumping unit of the present utility model is to have connected sleeve pipe short circuit, pump head, plunger cylinder and hydraulic cylinder successively in the lower end of pit shaft oil pipe, and the end opening of hydraulic cylinder has hydraulic fitting by the cylinder cap shutoff on cylinder cap.Well head is provided with reciprocating hydraulic pump on ground, and hydraulic pressure delivery side of pump connection hydraulic tube enters in the pit shaft and is connected on the hydraulic fitting of cylinder cap to the down-hole.
As further improvement of the utility model, piston is arranged in hydraulic cylinder, the plunger that links into an integrated entity with the axle center of piston extends in the plunger cylinder, and the inner chamber of plunger cylinder and the lumen shaft of pump head are to being communicated with.Seat suitable for reading at pump head has single ball valve and is communicated with pump discharge, and pump intake place seat has non-return valve, and the cavity of ball valve is communicated with pump head cavity through passage.
Further improving as the utility model, is to be provided with reciprocating hydraulic pump and its can also can enter pit shaft outside tube wall in the tube wall of oil pipe and be connected on the hydraulic joint of down-hole cylinder cap on the well head of ground.
The working principle of long-range hydraulic reciprocating pump pumping unit of the present utility model is to provide the hydraulic pressure frequency by the hydraulic reciprocating pump of being located at ground, this hydraulic pressure frequency be pulsed just, the negative wave power source, transfer to the reciprocating pump pumping unit of being located at the down-hole oil tube lower end through hydraulic tube, piston in the pumping unit oil hydraulic cylinder is also along with the hydraulic pressure frequency is back and forth moved, the non-return valve of the non-return valve of pump head outlet and pump head inlet also carries out rightabout repeat switch action according to this hydraulic pressure frequency, crude oil in the pit shaft is sucked from pump intake, through suppressing of plunger, enter oil pipe and flow to the ground well head continuously from pump discharge.Long-range hydraulic reciprocating pump pumping unit of the present utility model and the supporting use of horizontal well realize that the super large stroke recovers the oil, and this model utility has replaced traditional rocker-arm link reciprocating oil pumping unit of being located at ground (machine of kowtowing) fully from equipment and on the method.
That long-range hydraulic reciprocating pump pumping unit of the present utility model has is reasonable in design, simple in structure, reliable in mechanical performance, rate of fault is low, equipment volume is little, reduced land seizure, has advantages such as energy-conservation, safe, efficient, low cost.
