Description
Technical field
The utility model relates to the oil well pump that a kind of oilfield is used, and is specifically related to a kind of a kind of novel real stem stem plug anti-sticking that uses and deeply takes out oil well pump in the higher oil well of sand content.
Background technique
Present what mainly use at the higher oil well of sand content is the long-plunger pipe type sandproof oil-well pump, because plunger is longer, endoporus is less, flow channels is reduced, the crude oil flow resistance strengthens, and the descending power of plunger is larger simultaneously, has affected the gathering of crude oil, oil well pump inefficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of area of passage is large, oil flow resistance is little, a kind of novel real stem stem plug anti-sticking of high working efficiency is taken out oil well pump deeply.
The technical solution of the utility model is:
A kind of novel real stem stem plug anti-sticking is taken out oil well pump deeply, comprise rod connector, upper connection, supporting positive cover, pump barrel, outer tube, plunger, the pump barrel extension pipe, extension nipple, liquid feed valve, bridge-type joint inner tube, bridge-type joint outer tube, screen casing, it is characterized in that, plunger is real cored structure, pump barrel extension pipe lower end connects effluent Twin channel joint, effluent Twin channel joint lower end is connected with the fluid valve bonnet, liquid valve is installed in the fluid valve bonnet, Twin channel joint bottom outer wall is connected with Internal Pipe Thread, the inner tube lower end is connected with liquid feed valve, the liquid feed valve lower end is connected with bridge-type joint Internal Pipe Thread, and bridge-type joint inner tube is welded in the bridge-type joint outer tube.
Form two semi-circular channel between described bridge-type joint outer tube and the bridge-type joint inner tube.
The axial bore of described effluent Twin channel joint is communicated with the above and below of effluent Twin channel joint, around the radial hole connection fluid valve bonnet of effluent Twin channel joint and the effluent Twin channel joint.
Working principle of the present utility model is: when plunger is up, the pump barrel internal pressure descends, crude oil is entered by bridge-type joint inner tube through screen casing, liquid feed valve is opened, crude oil is entered in the pump barrel by Twin channel joint axial bore, when plunger is descending, the pump barrel internal pressure raises, crude oil is entered in the inner tube by Twin channel joint axial bore in the pump barrel, liquid valve is opened, crude oil by Twin channel joint radial hole enter effluent Twin channel joint around, enter effluent Twin channel joint around sand containing crude oil, sand grains sinks under Action of Gravity Field, and two semi-circular channel of formation sink under the pump in the tail pipe between bridge type joint outer tube and bridge-type joint inner tube.
The utility model plunger adopts real cored structure, and friction factor is little in the plunger upward and downward process, adopts side direction liquid valve structure, and area of passage is large, and oil flow resistance is little, has improved the working efficiency of oil well pump.
