Description
Technical field
Oil pumping in oil fields field of operation is the utility model is related to, belongs to the improvement of tubing pump structure, particularly one kind changes
The tubing pump entered.
Background technology
, it is necessary to oil well pump periodic inspection in the oil well using tubing pump.The oil well pump of traditional structure, there is following lack
Point：
1, conventional oil well pump upkeep operation is, it is necessary to propose rod string, then tubing string is proposed.Operation labor intensity
Greatly, operating cost is high.
2, between plunger and pump barrel, belong to metal gap cooperation.In oil recovery process, the friction pair that is made up of metal easily by
Influenceed to various factors, working environment is severe.Such as：The impurity effect such as eccentric wear phenomenon, sand, dirt.Working life is short, maintenance period
It is long.
3, fluid produces wastage by the fit clearance of plunger and pump barrel.After abrasion deformation, wastage is bigger, reduces
Pump efficiency.
Utility model content
The purpose of this utility model is to provide a kind of improved tubing pump, and its is rational in infrastructure, dependable performance, only needs
Rod string is proposed, without reintroducing tubing string, you can upkeep operation is carried out to oil well pump, pump detection and workover intensity is reduced, changes
Kind plunger and pump barrel friction condition, reduce wastage, improve pump efficiency, extend working life.
What the purpose of this utility model was realized in：A kind of improved tubing pump, including be engaged with pump barrel
What tubing pump connected with by on-off connector salvages standing valve, and oil pipe is connected on pump barrel, can salvage on standing valve and set
The block machine sealing surface put is engaged with the boss sealing surface on pump barrel inwall, and what is be uniformly arranged on the plunger of tubing pump is close
Coordinate in seal ring groove and flexible seal device is installed, the plunger of tubing pump is engaged by flexible seal device with pump barrel.
Operation principle of the present utility model：
1, installation process：
First pump barrel and tubing string are installed in place；Plunger and standing valve are transferred in place together again；Disengage plunger and fixation
Valve, start to pump；
Oil recovery state：The block machine sealing surface of standing valve can be salvaged to be engaged with the boss sealing surface on pump barrel inwall, tubular type
The on-off connector top of oil pump plunger piston connection disengages with that can salvage the on-off connector bottom being connected on standing valve；2nd, tubular type oil pumping is transferred
Pump, the on-off connector top that tubing pump plunger connects is set to be docked with the on-off connector bottom being connected on standing valve can be salvaged；3rd, on
Sucker rod is carried, tubing pump is proposed outside oil well together with it can salvage standing valve, you can maintenance tubing pump.
1, it is mature technology that can salvage standing valve, can be screw thread salvaging type, or track salvaging type etc.；
2, soft sealing plunger or compound plunger, material can be carried out according to specific well conditions from wearability, corrosion resistance etc.
Selection, ensure that the part that on plunger and pump barrel contacts is softer than pump barrel inwall, concrete structure is not construed as limiting；So improve plunger and
The condition of work of pump barrel friction pair, reduce pump barrel inner wall abrasion.Meanwhile plunger and pump barrel gap reduce, wastage substantially reduces.
3, durable pump barrel, by from the high tubing of intensity, and interior wall processing technology, improving pump barrel intensity.
The utility model is rational in infrastructure, dependable performance, and need to only rod string be proposed by realizing, without reintroducing oil pipe
Post, you can upkeep operation is carried out to oil well pump, pump detection and workover intensity is reduced, improves plunger and pump barrel friction condition, is reduced
Wastage, improves pump efficiency, extends working life.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is the utility model oil recovery state section view
Structural representation, Fig. 2 are the utility model mated condition cross section structure diagram.
