Abstract
The utility model provides a two effect oil -well pumps who uses on the oil field, its aim at: the problem of big discharge capacity two effect oil -well pumps structure is complicated, the vulnerable part is many, the processing degree of difficulty is big, the oil -well pump is short -lived is solved. This two effect oil -well pumps is by last pump, lower pump and middle sealed vice the constitution, going up the pump and compriseing last pump barrel and last plunger, the upper prop has the traveling valve beyond the great wall, the pump comprises lower pump barrel and lower plunger down, and there is the standing valve lower pump barrel bottom, upward the pump barrel links to each other through sealed vice urceolus in centre and lower pump barrel, and upward the plunger is filled in with traveling valve, sealed auxiliary pillar, the plunger is consecutive down. This invention is compared its advance with other two effect oil -well pumps and is lain in: abandoned vulnerable parts such as eccentrically arranged valve in general use, cone valve, all valve members all adopt ripe reliable oil -well pump standard component, have improved the reliability of valve member, and not only the big liquid stream resistance of runner is little, and the pump efficiency is high, and only need two sleeving valves vice in the principle, have reduced manufacturing cost, have prolonged the life of oil -well pump.
Description
Technical field
The present invention relates to a kind of oil field rod pumping pump, particularly relate to all double acting sucker rod pumps of fluid of a kind of up-down stroke.
Background technology
The most of oil field developments of China are all to the middle and later periods, well liquid moisture more and more higher, and production fluid amount is also increasing, and what generally take for the higher oil well of production fluid amount is electric submersible pumping mode, and still, electric submersible pump cost is high, power consumption is many, and cost of winning is higher. For addressing this problem, there is the patent of many large discharge capacity rod pumping pumps to come forth: as Chinese patent (application number) 201420307217.2 has been announced a kind of double acting sucker rod pump, and for example Chinese patent (application number) 201210458851.1 has been announced a kind of parallel-type double-cavity oil well pump, and the technical purpose that such oil well pump will be realized is exactly under the constant prerequisite of oil pumper manufacturing parameter, to increase oil pumping pump delivery. But the common issue that they exist is to have adopted off-gauge valve group such as eccentrically arranged valve or cone valve, and the problem of bringing is exactly that oil-feed efficiency and functional reliability are all very low, causes the life-span of oil well pump short. Although feasible principle, practicality is poor, do not obtain user's accreditation.
Summary of the invention
The present invention is just to provide one can overcome the deficiencies in the prior art, and a kind of reliable operation, the large quantity oil pump of double acting with low cost, long service life are provided.
The technical solution adopted in the present invention is: this double acting sucker rod pump is made up of upper pump, lower pump and intermediate seal pair; Upper pump is made up of upper pump barrel and upper plug, has travelling valve on upper plug; Lower pump is made up of lower pump barrel and lower plunger, and standing valve is arranged at lower pump barrel bottom; Upper pump barrel is connected with lower pump barrel by the secondary urceolus of intermediate seal, and upper plug is connected successively with travelling valve, sealing pair plunger, lower plunger.
Preferably, described double acting sucker rod pump, its sealing pair plunger upper end has epicoele intercommunicating pore.
Preferably, described double acting sucker rod pump, its lower plunger body is directly connected and seals with sealing pair plunger.
Preferably, described double acting sucker rod pump, its sealing pair plunger is hollow, has the fluid course that connects epicoele and cavity of resorption.
Preferably, described double acting sucker rod pump, there is the lumen intercommunicating pore being connected with oil jacket annular space its lower pump barrel upper end.
The outstanding advantages that this invention has compared with prior art is: all valve members all adopt the oil well pump standard component of mature and reliable, improved the reliability of valve pair, not only the large liquid flowing resistance of runner is little, and in principle, only needs two sleeving valve pairs, reduce manufacturing cost, extended the service life of oil well pump.
Brief description of the drawings
Accompanying drawing is the structural representation of this invention.
In accompanying drawing: [1] upper pump barrel; [2] upper plug; [3] travelling valve; [4] epicoele intercommunicating pore; [5] epicoele; [6] sealing pair urceolus; [7] cavity of resorption intercommunicating pore; [8] lumen; [9] sealing pair plunger; [10] lower plunger; [11] lower pump barrel; [12] cavity of resorption; [13] standing valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated, and a kind of preferred forms is provided.
Upper pump barrel [1] and lower pump barrel [11] all can adopt standard component, and be connected with sealing pair urceolus [6] by reducer union, lower pump barrel [11] lower end is connected with standing valve [13], the built-in upper plug of upper pump barrel [1] [2], a travelling valve can be respectively installed at the upper and lower two ends of upper plug [2], the travelling valve [3] of upper plug [2] lower end can be connected by reducer union with sealing pair plunger [9], sealing pair plunger [9] also will be by reducer union with being connected of lower plunger [10] upper end, travelling valve [3] on upper plug [2] can be arranged on the lower end of plunger body, also can be arranged on upper end, a delivery valve also can be respectively set up and down, epicoele intercommunicating pore [4] and lumen intercommunicating pore [7] are respectively at plunger seal pair [9] and lower pump barrel [11] overpunch, all valve pairs of the present invention, plunger body and pump barrel all can adopt standard component, structure is extremely simple, implementation detail does not repeat them here more specifically.
Operation principle of the present invention is: when upstroke, standing valve [13] is opened, and well liquid is full of cavity of resorption [12] and enters epicoele [5] through hollow duct and the epicoele intercommunicating pore [4] of lower plunger [10], sealing pair plunger [9], and up discharge capacity is pump delivery; When down stroke, standing valve [13] cuts out, travelling valve [3] is opened, well liquid in cavity of resorption [12] enters on pump through lower plunger [10], sealing pair plunger [9] and upper plug [2], the displacement of completed well liquid, simultaneously, well liquid in epicoele [5] enters on pump through upper intercommunicating pore [4] and travelling valve [3], descending discharge capacity is the annular space volume of epicoele [5], this all discharge opeing of pump up-down stroke, and historical facts or anecdotes has showed the goal of the invention of oil well pump double acting discharge opeing. The effect of lower intercommunicating pore [7] is to prevent that lumen [8] from becoming dead space, causes oil well pump normally to work.
The above embodiments are only a kind of simple concrete embodiments the invention is intended to; above-mentioned travelling valve and the position of standing valve and number; in the situation that not affecting its operation principle, all can change; the position of intercommunicating pore can also can be in reducer union in the position of above-mentioned accompanying drawing, and above-mentioned various variations and combination are all within protection scope of the present invention.
