The forward and reverse washing well oil-well pump comprises an upper joint hoop, a plunger assembly, a standing valve assembly, a working pump cylinder, a lower joint hoop and an outer cylinder, wherein the outer cylinder is connected on the lower portion of the upper joint hoop through an external thread, the working pump cylinder is is connected on the lower portion of the upper joint hoop through an internal thread, and the plunger assembly penetrates through the upper joint hoop and is connected with the upper joint hoop. The working pump cylinder is sleeved outside the plunger assembly, the standing valve assembly is connected on the lower portion of the working pump cylinder by the lower joint hoop, a well washing hole is formed in the working pump cylinder, and gaps are reserved among the working pump cylinder, the lower joint hoop, the standing valve assembly and the outer cylinder. The forward and reverse washing well oil-well pump is simple in structure, ingenious in design concept, and scientific and reasonable in structure. The forward and reverse washing well washing oil pump is structurally characterized in that when the plunger assembly is drawn out of the working pump cylinder, a liquid channel is formed among the working pump cylinder, a centralizing cylinder, the lower joint hoop, the standing valve assembly and the outer cylinder, and the forward and reverse washing well washing oil pump can be used for forward and reverse well washing.
Description
Technical field
The utility model relates to a kind of forward and reverse well-flushing oil well pump, belongs to the oil production equipment field.
Background technology
Oil well pump is important in a underground equipment link in the oil exploitation industry, not only be used for oil producing operation, when oil well need clean, flushing fluid entered the shaft bottom by the ring set space between the tubing and casing, enter in the oil pipe by oil well pump then, thereby reach the effect of well-flushing.Yet this pumping and washing process is single a bit, and degree of cleaning can not reach ideal effect, therefore propose the method for forward and reverse well-flushing in the oil well operation at present, but conventional oil well pump is not but supported this two-way well-flushing method.
Summary of the invention
The purpose of this utility model is to provide a kind of forward and reverse well-flushing oil well pump to solve above problem.
The technical scheme that the utility model provides is:
Forward and reverse well-flushing oil well pump, comprise box cupling, assembly for plunger, standing valve assembly, work pump barrel, following box cupling and urceolus, last box cupling below external screw thread connects urceolus, last box cupling below internal thread connection work pump barrel, assembly for plunger passes box cupling and is connected with last box cupling, and the working barrel jacket casing is in the assembly for plunger outside, and work pump barrel below is connected with the standing valve assembly by following box cupling, the work pump barrel is provided with well washing hole, between work pump barrel, following box cupling, standing valve assembly and the urceolus slit is arranged.
Concrete, the urceolus lower end is connected with the bottom box cupling, between bottom box cupling and the standing valve assembly slit is arranged.
Concrete, the work pump barrel is connected with following box cupling by setting upright tube.
Concrete, described standing valve assembly is made of standing valve cover, standing valve pair, standing valve joint, and standing valve cover is connected with the standing valve joint and the standing valve sub-folder is held between the two.
Concrete, described assembly for plunger is made of upper traveling valve cage, upward-traveling valves pair, center tap, plunger body, lower travelling valve cover, lower travelling valve pair, pipe close, upper traveling valve cage, center tap, plunger body, lower travelling valve cover, pipe close link to each other successively, the upward-traveling valves pair is that upper traveling valve cage and center tap clamp, and the lower travelling valve pair is that lower travelling valve cover and pipe close clamp.
The utility model is simple in structure, and design concept is ingenious, and is scientific and reasonable for structure, its design feature is, when outside the assembly for plunger proposition work pump barrel, the work pump barrel, set upright tube, form a fluid passage between box cupling, standing valve assembly and the urceolus down, can be used for well cleanout and reverse cleanout.
