Detailed description of the invention
As Figure 1-Figure 2, efficiently divide and adopt double acting sucker rod pump, including pump barrel assembly and the post being arranged in pump barrel assembly Plug assembly, pump barrel assembly is double-decker, and the lower end of pump barrel assembly is provided with two oil-ins, two oil-ins respectively with pump barrel Internal layer and the outer layer of assembly communicate, and are provided with down stroke sealing device between pump barrel assembly and the upper end of assembly for plunger.
Assembly for plunger is arranged in the endothecium structure of pump barrel assembly.
Pump barrel assembly includes upper box cupling 15, cross under 11 and the duplex fitting 7 being sequentially connected with, and the lower end of duplex fitting 7 is entered Oil port is provided with lower standing valve 6, and connecting at the lateral oil-in of duplex fitting 7 has upper standing valve 8, upper standing valve 8 upper end to set It is equipped with lower pump barrel 12.
Assembly for plunger is arranged in lower pump barrel 12, upper delivery valve 16 that assembly for plunger includes being sequentially connected with, upper plug 13, under Plunger 10 and lower delivery valve 9, be provided with pump barrel 14 in the outside of upper plug 13.
Down stroke sealing device includes annular valve ball 2 and ring-shaped valve seats 3, and the upper end of upper pump barrel 14 is provided with jag and is formed Annular valve ball 2, is provided with the ring-shaped valve seats 3 coordinated with annular valve ball 2 on upper box cupling 15.
Circular passage is formed between lower pump barrel 12 and cross under 11.
Upper plug 13 is structure as a whole with lower plunger 10, and upper plug 13 and lower plunger 10 constitute inverted T shape structure.
Upper box cupling 15 upper end is provided with elastic lock claw 1, for being connected with oil pipe 17.
It is internal that lower pump barrel 12 is sleeved on cross under 11, and lower pump barrel 12 cylindrical and cross under 11 endoporus surround circular passage, under Pump barrel 12 lower end is connected with duplex fitting 7, and duplex fitting 7 is internal two mutually isolated passages, and one by lateral oil-in 5 With lower pump barrel 12 UNICOM, one by lower standing valve 6 and circular passage UNICOM.
Efficiently divide and adopt double acting sucker rod pump operation principle:
During upstroke, upper and lower delivery valve cuts out, and lower plunger 10 lower pumping chamber volume increases, and pressure declines, and upper standing valve 8 is opened, Down-hole fluid is pump chamber from the lateral oil-in 5 of duplex fitting 7 enters, completes 1 strike the oil;Simultaneously, lower standing valve 6 cuts out, Lower plunger 10 upper pumping chamber volume reduces, and pressure increases, and upper pump barrel 14 moves, and annular plate valve 2 is opened, in lower plunger 10 upper pumping chamber Fluid enters on pump in oil pipe 17 by annular plate valve 2, completes 1 oil extraction.
During down stroke, upper standing valve 8 cuts out, and lower plunger 10 lower pumping chamber volume reduces, and pressure increases, upper and lower delivery valve Opening, lower pump chamber inner fluid enters on pump in oil pipe 17 by plunger endoporus, completes 2 oil extractions;Simultaneously, upper pump barrel 14 times Moving, annular plate valve 2 cuts out, and lower plunger 10 upper pumping chamber volume increases, and pressure reduces, and lower standing valve 6 is opened, and down-hole fluid passes through ring Shape passage enters in lower plunger 10 upper pumping chamber, completes 2 strike the oils.
Owing to one reciprocal stroke of the present invention can complete the process of twice strike the oil and oil extraction, theoretical displacement is than pump footpath and work The identical oil well pump of parameter improves about 50%, can be effectively improved oil well output.
Present invention annular plate valve 2 instead of the circulation valve in conventional double-acting pump, improves the reliability of valve body, can be effective Extend pump detection period.Simultaneously, it is no longer necessary to use on-off connector.
Owing to the oil inlet passage of the present invention has two-way and mutually isolated, therefore can realize separate zone production by supporting packer, solve Certainly between oil reservoir interlayer interference, improve recovery ratio.
The present invention is formed by special structures in series by the oil well pump in upper and lower two different pump footpaths, and centre is sealed, May be implemented in 2 oil extractions and the strike the oil process of completing in a reciprocal stroke, be effectively improved pumpage, it is achieved small pump diameter huge discharge is adopted Oil.Meanwhile, by annular plate valve 2 and the setting of duplex fitting 7, oil inlet passage is separated into two-way, also can realize separate zone production.This Invention is applicable to the oil well that feed flow is sufficient.
Above-described is only the preferred embodiment of the present invention, it is noted that for a person skilled in the art, Without departing under general idea premise of the present invention, it is also possible to making some changes and improvements, these also should be considered as the present invention's Protection domain.
