Abstract
A fracturing and swabbing combined oil-well pump comprises an outer cylinder portion, a working cylinder portion and a swabbing portion, and is characterized in that the outer cylinder portion comprises an outer cylinder, a sealing cylinder, an upper connecting hoop and a lower connecting hoop; the sealing cylinder and the upper connecting hoop are sequentially connected at the upper end of the outer cylinder, and the lower connecting hoop is connected at the lower end of the outer cylinder; the work cylinder portion comprises a pump cylinder, a sealing body, a slide valve cover, a liquid inlet valve group and a positioning lock claw, the sealing body and the slide valve cover are sequentially connected at the upper end of the pump cylinder; the liquid inlet valve group and the positioning locking claw are sequentially connected onto the lower end of the pump cylinder; the swabbing portion comprises a plunger piston, an oil outlet joint, a pull rod, a pull rod joint and a liquid outlet valve group; the plunger piston, an oil outlet joint, a pull rod and a pull rod joint are sequentially connected at the upper end of the plunger piston, the liquid outlet valve group is connected at the lower end of the plunger piston, the swabbing portion is mounted in an inner cavity of the pump cylinder, the working cylinder portion is mounted inside an inner cavity of an outer cylinder, and the pull rod and the pull rod joint extend outside the pump cylinder and the outer cylinder. The fracturing and swabbing combined oil-well pump has the advantages of directly, quickly and rotatably pumping and discharging liquid, reducing operation procedures, shortening oil testing time, and improving oil testing efficiency, and being mainly applied to the technology of fracturing and swabbing discharge liquid in exploration wells of petrol.
Description
One, technical field
The utility model relates to field exploratory well formation testing and oil reservoir to be handled the back and changes to take out and use downhole pump, and particularly a kind of pressure break pumping joins makes oil well pump.
Two, background technique
Wellfracturing is changeed odd test oil after handling, and adopts conventional tubing pump to carry out usually, and this mode exists following shortcoming or deficiency: 1. need to trip out former well fracturing string, and then be lowered to flow string, flow chart is many, changes the length of finding time; 2. rise in the lower tubular column process and overflow or blowout may occur, have safety and environmental protection hidden danger; 3. need kill-job before descending pump, oil reservoir is caused secondary pollution, influence formation testing effect and production efficiency.
Three, summary of the invention
The purpose of this utility model provides a kind of pressure break pumping connection and makes oil well pump, adopt the integrated mode of doing of pressure break pumping, can either realize that direct commentaries on classics of motionless fracturing string is drawn into capable quick fluid-discharge, reduce cargo handling operation, shorten the formation testing time, improve formation testing efficient, the shortcoming or the deficiency that overcome effectively again or avoid existing in the above-mentioned prior art.
Pressure break pumping connection described in the utility model is made oil well pump, comprises urceolus part, working barrel part and pumping part, it is characterized in that sealing drum and last box cupling that described urceolus comprises that partly urceolus and upper end thereof connect in turn, the following box cupling that the lower end connects; Described working barrel partly comprises seal and the guiding valve cover that pump barrel and upper end thereof connect in turn, feed liquor valve group that the lower end connects in turn and location lock pawl; Described pumping partly comprises delivery connection, pull bar and the rod head that plunger and upper end thereof connect in turn, the liquid valve group that the lower end connects; Pumping partly is installed on the pump barrel inner chamber, and working barrel partly is installed on outer tube inner chamber, and described pull bar and rod head stretch out pump barrel and urceolus.
Wherein, described seal is installed in the sealing drum, the annular space between sealed outer cylinder and the pump barrel.Described location lock pawl is placed in down the box cupling lower lumen, fixing, spacing and seal operation tube.
Compared with the prior art the utility model has following innovative point:
1, adopt the soft or hard double sealing structure, sealingly secure is reliable, effectively reduces leakage, improves pump efficiency;
2, adopt location lock jaw arrangement, grappling is reliable, and spacing accurate, sealing is strong;
3, can reduce by twice lower tubular column operation, shorten the oil extraction cycle, reduce and press after stain, keep fracturing effect, reduce labor intensity, raise the efficiency;
4, need not kill-job during operation, avoided secondary pollution.
Four, description of drawings
Accompanying drawing is a kind of enforcement structural representation of the present utility model.
Five, embodiment
Consult accompanying drawing, a kind of pressure break pumping connection is made oil well pump, comprises urceolus part, working barrel part and pumping part.Urceolus partly comprises sealing drum 5 and the last box cupling 3 that urceolus 11 and upper end thereof connect in turn, the following box cupling 14 that the lower end connects; Working barrel partly comprises seal 6 and the guiding valve cover 4 that pump barrel 7 and upper end thereof connect in turn, feed liquor valve group 12 that the lower end connects in turn and location lock pawl 13; Pumping partly comprises delivery connection 8, pull bar 2 and the rod head 1 that plunger 10 and upper end thereof connect in turn, the liquid valve group 9 that the lower end connects; Pumping partly is installed on pump barrel 7 inner chambers, and working barrel partly is installed on urceolus 11 inner chambers.Pull bar 2 and rod head 1 stretch out pump barrel 7 and urceolus 11.
Seal 6 is installed in the sealing drum 5, the annular space between sealing pump barrel 7 and the urceolus 11.Location lock pawl 13 is placed in down box cupling 14 lower lumen, fixing, spacing and seal operation tube.
During The field, the urceolus part is with the fracturing string G.I.H; Open flow finishes after the pressure break, and the working barrel part is lowered in the tubing string with rod string, directly carries out pump pump drainage liquid, reduces by twice lower tubular column operation, shortens the oil extraction cycle, reduces and presses after stain, improves formation testing efficient.
