Abstract
A hydraulic feedback pump capable of preventing air lock. The problem of current hydraulic feedback pump easily produce the airlock phenomenon when the produced fluid contains low water, gas content is high is mainly solved. The method is characterized in that: the coupling is characterized in that a water nozzle hole is formed in the side wall of the middle of the coupling main body (1), two layers of filter screens (2) are arranged on the end face of the water nozzle hole, a water nozzle (3) is arranged between the two layers of filter screens (3), a sealing gasket (5) is arranged outside the outer layer of filter screen (2), and a water nozzle seat (4) is connected to the water nozzle hole outside the sealing gasket (5). The hydraulic feedback pump capable of preventing air lock can greatly reduce the air lock phenomenon, and achieve the purpose of improving the pump efficiency of the produced liquid of the gas-containing well.
Description
Technical field
The present invention relates to oilfields, specifically a kind of to prevent the hydraulic feedback of gas lock from pumping.
Background technique
The characteristics of hydraulic feedback pump used in the single-well injection-production technology of high water cut oil field application, the pump is in up-down stroke
Two valves of oil well pump are all with plunger associated movement in the process, as shown in Fig. 2, pass through lower plunger 12 during upstroke
The annular volume between upper plug 8 and lower pump barrel 9 is squeezed, the liquid in the annular space is expelled in oil pipe.Due to single-well injection-production
Technology needs to adjust separately the discharge capacity ratio of top extraction pump and lower part injection pump, therefore top extraction pump is under lower pump barrel 9
Portion uses the structure of grooving dredging flow groove 13, and the initial position by changing lower plunger 12 changes effective stroke and the row of extraction pump
Amount.Due to the reduction of effective stroke, upper plug 8 and the volume of lower 9 annular space of pump barrel are also reduced therewith, when Produced Liquid is aqueous low, gas
Body content will generate gas lock phenomenon when high.
Summary of the invention
In order to overcome existing hydraulic feedback pump when Produced Liquid it is aqueous it is low, gas content is high when be also easy to produce gas lock phenomenon not
Foot, the present invention, which provides one kind, can prevent the hydraulic feedback of gas lock from pumping, this can prevent the hydraulic feedback of gas lock from pumping and can greatly reduce
Gas lock phenomenon achievees the purpose that production fluid containing gas well to improve pump efficiency.
The technical scheme is that a kind of can prevent the hydraulic feedback of gas lock from pumping, including box cupling main body, the box cupling master
Water nozzle hole is provided on side wall in the middle part of body, water nozzle hole internal end surface is equipped with two layers of filter screen, is equipped with water between two layers of filter screen
Mouth is equipped with gasket outside outer filter net, is connected with water nozzle seat on the water nozzle hole outside gasket.
The box cupling main body upper and lower ends are separately connected top short pump barrel and lower pump barrel.
The invention has the following beneficial effects: due to taking above scheme, water nozzle is installed in box cupling main body, in oil well pump
When upstroke, the gas in pump chamber can be discharged, avoid that gas lock phenomenon occurs, the mesh for improving pump efficiency is reached to production fluid containing gas well
's；Water nozzle is located between two layers of filter screen, can block water nozzle to avoid impurity；Water nozzle uses hard alloy, increases when being vented
Service life, hard alloy processing guarantee precision and reasonable capacity using laser cutting.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the schematic diagram of hydraulic feedback pump.
1- box cupling main body in figure, 2- filter screen, 3- water nozzle, 4- water nozzle seat, 5- gasket, the top 6- short pump barrel, 7- box cupling,
8- upper plug, pump barrel under 9-, the fuel-displaced valve of 10-, 11- oil inlet valve, plunger under 12-, 13- drain pan.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
As shown in Fig. 1, Fig. 2, a kind of hydraulic feedback preventing gas lock is pumped, including box cupling main body 1, the box cupling main body 1
Water nozzle hole is provided on the side wall at middle part, water nozzle hole is the small stepped hole of outer imperial palace, and internal cascaded surface is equipped with two layers of filtering
Net 2 is equipped with water nozzle 3 between two layers of filter screen 3, and water nozzle 3 is directed at the aperture of stepped hole, and 3 diameter of water nozzle is 0.1-1.0mm.Outside
It is equipped with gasket 5 outside layer filter screen 2, water nozzle seat 4 is threaded on the water nozzle hole outside gasket 5, water nozzle seat 4 will seal
Pad 5, filter screen 2 and water nozzle 3 are fixed in hole, and filter screen 2 can prevent water nozzle 3 from blocking, and gasket 5 can make the gas in pump
And liquid can only be by 3 row of water nozzle to oil jacket annulus.
1 upper and lower ends of box cupling main body are separately connected top short pump barrel 6 and lower pump barrel 9, are equipped with upper prop inside lower pump barrel 9
Plug 8,8 bottom of upper plug are equipped with fuel-displaced valve 10, and fuel-displaced 10 bottom of valve is by being shorted connection oil inlet valve 11, oil inlet valve 11
Valve seat bottom connect lower plunger 12.Drain pan 13 is provided in 9 bottom sidewall of lower pump barrel.Water nozzle 3 is mounted on box cupling master
On body 1, in oil well pump upstroke, the gas in pump chamber can be discharged.Water nozzle 3 uses hard alloy, makes when increasing exhaust
With the service life, hard alloy processing guarantees precision and reasonable capacity using laser cutting, reaches raising pump to production fluid containing gas well
The purpose of effect.
