Description

Three plunger mining pumps
Technical field
It the utility model is related to a kind of mining equipment, specifically a kind of three plungers row suitable for high angle hole, horizontal well Adopt pump.
Background technology
During oil field production, cbm development, with drilling well, the development of mining technology, high angle hole and horizontal well Increase.Tradition has bar mining equipment to occur many new problems in process of production, as sucker rod break caused by eccentric wear it is de-, oil pipe because Eccentric wear is scrapped, and pump detection period shortens;Although researching and developing various no bar mining equipment energetically both at home and abroad, as electric submersible screw pump, electric submersible pump, Hydraulic piston pump, jet pump, these mining equipment are unsatisfactory at present, are technically all difficult to break through, and have and itself are difficult to overcome The defects of, do not possess practicality.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided one kind is applied to high angle hole and level Well, the eccentric wear problem of beam hanger lifting technology, three plunger mining pumps of mining efficiency high are thoroughly prevented.
The technical solution of the utility model is:
Three plunger mining pumps, including outer barrel, the outer barrel top are provided with power fluid mouth, and hydraulic cylinder and small is set in outer barrel Pump barrel, small pump barrel lower end connect big pump barrel, and the internal diameter of small pump barrel is less than the internal diameter of hydraulic cylinder and big pump barrel, hydraulic cylinder upper end Production liquid pipe is set, has annular space, hydraulic cylinder lower sides liquid outlet channel between outer barrel and hydraulic cylinder, small pump barrel contacts with outer barrel Seal and fix, cylinder plunger, big plunger respectively in the hydraulic cylinder and big pump barrel, cylinder plunger, big plunger it is outer Footpath is more than the internal diameter of small pump barrel, the upper and lower ends difference connection liquid cylinder pressure plunger of small plunger and big plunger, cylinder plunger, pillar Plug and big plunger are hollow structure and are interconnected, and upper check valve is set in small plunger, and big plunger base sets lower check valve, greatly Its upper end was provided with liquid passage, the annular space crossed between the big plunger inner space of liquid passage connection and small plunger and big pump barrel.
Centralizer is set between the outer barrel and hydraulic cylinder, fluid hole is provided with centralizer.
The big pump barrel is located at below outer barrel.
The cylinder plunger, small plunger and big plunger integrally connected.
The utility model is gone beyond the Great Wall by power fluid driving hydraulic cylinder plunger, small plunger, huge pillar, is driven by hydraulic feedback power Hydrodynamic pressure cylinder plug, small plunger, big plunger are descending, realize no bar mining, have thoroughly prevented the eccentric wear problem of beam hanger lifting technology; The utility model is simple in construction, energy consumption is low, mining efficiency high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
The small plunger 8 of 16 cylinder plunger of production liquid pipe 2 power fluid mouth, 3 outer barrel, 4 centralizer, 5 hydraulic cylinder 7 The upper big fluid hole A1 liquid outlet channel A2 mistakes of pump barrel 13 of the big 11 times check valves of plunger 12 of the small pump barrel 10 of check valve 9 Liquid passage X1 small plungers are formed with the big plunger inner space X3 small plungers of the annular space X2 that big pump barrel is formed with hydraulic cylinder The annular space that is formed of annular space X4 hydraulic cylinders and outer barrel.
Embodiment
Three plunger mining pumps, including outer barrel 3, the top of outer barrel 3 are provided with power fluid mouth 2, hydraulic cylinder are set in outer barrel 3 5 and small pump barrel 9, centralizer 4 is set between outer barrel 3 and hydraulic cylinder 5, fluid hole, the upper end of hydraulic cylinder 1 are provided with centralizer 4 Production liquid pipe 1 is set, and the upper end of outer barrel 3 is stretched out in production liquid pipe upper end.
The small lower end of pump barrel 9 connects big pump barrel 12, and big pump barrel 12 is located at the lower section of outer barrel 3, and the internal diameter of small pump barrel 9 is less than hydraulic cylinder The internal diameter of cylinder 5 and big pump barrel 12, there is annular space X4, the lower sides liquid outlet channel A1 of hydraulic cylinder 5 between outer barrel 3 and hydraulic cylinder 5, Small pump barrel 9 contacts with outer barrel 3 to be sealed and fixes.
Cylinder plunger 6, big plunger 10 are respectively positioned at hydraulic cylinder 5 and greatly in pump barrel 12, cylinder plunger 6, big plunger 10 external diameter is more than the internal diameter of small pump barrel 9, the upper and lower ends difference connection liquid cylinder pressure plunger 6 and big plunger 10 of small plunger 7, hydraulic pressure Cylinder plug 6, small plunger 7 and the big integrally connected of plunger 10, the annular space X1 that small plunger is formed with big pump barrel, small plunger and hydraulic cylinder Cylinder forms annular space X3, and cylinder plunger 6, small plunger 7 and big plunger 10 are hollow structure and be interconnected, and are set in small plunger 7 Upper check valve 8, the big bottom of plunger 10 set lower check valve 11, and the big upper end of plunger 10 was provided with liquid passage A2, crosses liquid passage A2 and connects The annular space X1 led between big the inner space X2 of plunger 10 and small plunger 7 and big pump barrel 12.
Operation principle of the present utility model is:Up stroke, power fluid pass sequentially through power fluid mouth 2, production liquid pipe 13 and outer barrel 3 Annular space X4, the liquid outlet channel A1 that the annular space of formation, hydraulic cylinder 5 are formed with outer barrel 3, into the annular space X3 of hydraulic cylinder bottom, With the increase of power fluid pressure, promote cylinder plunger 6 up, drive small plunger 7, big plunger 10 up, it is now lower unidirectional Valve 11 is closed, and annular space X1 is compressed, and pressure rises, and annular space X1 production liquid enters space X 2, and by pressure transmission, check valve is opened on top 8, through small plunger 7, cylinder plunger 6, into production liquid pipe 13.
Down stroke, Surface power drive hydraulic coupling reduce, and due to the differential pressure action in production fluid column and annular space X1, space X 2, produce liquid Head of liquid is much larger than upper check valve fluid pressure below 8, and production liquid head of liquid is much larger than the big bottom of pump barrel 12 and outside liquid Pressure, forms hydraulic feedback power, and upper check valve 8 is closed.It is cylinder plunger 6, small plunger 7, big in the presence of hydraulic feedback power Plunger 10 is descending.The lean liquor of the bottom of cylinder plunger 6 is pushed back, and the annular space X4 formed by hydraulic cylinder 5 and outer barrel 3, produces liquid The annular space that pipe 1 is formed with outer barrel 3, returns to ground.
Finally it should be noted that:Above example is only illustrating the technical solution of the utility model rather than it is limited System;Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should Understand:Specific embodiment of the present utility model can still be modified or some technical characteristics are equally replaced Change;Without departing from the spirit of technical solutions of the utility model, it all should cover in the claimed technical scheme of the utility model Among scope.
