Abstract
The invention relates to a hydraulic self-sealed oil plunger pump with a multistage pump cylinder, which mainly solves the problem that the hydraulic self-sealed oil plunger pump with a multistage pump cylinder in the prior art has short service life and needs to pull down an oil pipe when the pump cylinder is replaced. The hydraulic self-sealed oil plunger pump is characterized in that a T-shaped boss (11) is arranged at the center of the inner side of a coupling (2); a supporting frame (4) connected with a fishing valve (7) is arranged on the upper part of a fixed valve (1); a liquid outlet groove (10) is arranged on the upper part of the fishing valve (7) and is matched with a fixed claw (12); the upper part of the fishing valve (7) is connected with a plunger (9) through a connecting rod (13); and fishing shoulders (15) are arranged on the upper part of the outer circumferential groove of the connecting rod (13). According to the hydraulic self-sealed oil plunger pump, when the plunger and the pump cylinder are worn to fail operation, the plunger can be conveniently replaced, the operation of pulling down the oil pipe is not needed, and the service life of the pump is prolonged.
Description
Technical field
The present invention relates to the field, oil field, a kind of specifically multistage pump barrel hydraulic self-sealed plunger oil-well pump.
Background technique
In oil recovery field, oil field, it is one of traditional artificial lifting way of World Oil Industry that the oil pumping of bar plunger pump is arranged, and also is prevailing up to now artificial lift mode.The phase I of sucker-rod pumping technical development is the bush type plunger pump, and second stage is whole cartridge type plunger pump, and the new stage is a hydraulic pressure self-sealing plunger pump, and hydraulic pressure self-sealing plunger pump has reached the effect of ultralow leakage, ultra low friction resistance, superelevation pump efficiency.Yet plunger pump in underground work; Because the long-term eccentric wear of plunger and pump barrel causes pump barrel short working life; Standing valve is easily fouling and lose its effect under the wearing and tearing of sand or in the ternary displacement of reservoir oil well also, needs periodic replacement at present, still changes pump barrel and standing valve need remove the oil pipe operation; Waste time and energy, increased the oil extraction cost greatly.
Summary of the invention
In order to overcome deficiency above-mentioned in the existing technology; The present invention provides a kind of multistage pump barrel hydraulic self-sealed plunger oil-well pump, when this multistage pump barrel hydraulic self-sealed plunger oil-well pump lost efficacy after plunger and pump barrel wearing and tearing, and conveniently replaced plunger; Needn't remove the oil pipe operation, prolong the working life of pump.
Technological scheme of the present invention is: a kind of multistage pump barrel hydraulic self-sealed plunger oil-well pump; Comprise standing valve, plunger, upper and lower pump barrel; Described going up between pump barrel and the standing valve is connected through box cupling, and described box cupling middle inside circumferencial direction is provided with T shape boss, and described standing valve top is provided with the supporting frame that links to each other with the salvagable valve; Supporting frame lower end exterior periphery direction is provided with the groove that matches with T shape boss; The groove bottom is provided with fixed claw, and the plane is provided with the liquid outlet opening groove on the liquid outlet opening on described salvagable valve top, and described liquid outlet opening groove and fixed claw match;
Described salvagable valve top is connected with connecting rod, and the connecting rod excircle has the outside thread that matches with the internal thread of plunger base, and the connecting rod exterior circumferential is provided with groove, groove top formation salvaging shoulder.
This multistage pump barrel hydraulic self-sealed plunger oil-well pump also comprises fishing head, and described fishing head bottom is provided with to projecting inward bailer grab, and described bailer grab matches with the salvaging shoulder.
Be provided with seal ring between described salvagable standing valve outside and the last pump barrel.
The present invention has following beneficial effect: owing to take such scheme; When the standing valve of bottom can not work on owing to wearing and tearing; A salvagable standing valve can be installed on standing valve top again; Seal between the salvagable standing valve on top and the last pump barrel, make plunger above pump barrel section to work on.Therefore, saved and removed the time that oil pipe is changed pump barrel, but compared life-saving more than 2 times, practiced thrift the oilfield exploitation cost with original common oil well pump.

Embodiment:
Below in conjunction with accompanying drawing the present invention is described further:
To shown in Figure 3, a kind of multistage pump barrel hydraulic self-sealed plunger oil-well pump comprises standing valve 1, plunger 9, upper and lower pump barrel (8,3) by Fig. 1, connects through pump barrel box cupling 5 between the upper and lower pump barrel (8,3), and plunger 9 is a hydraulic self-sealed plunger.Described going up between pump barrel 3 and the standing valve 1 is connected through box cupling 2, and described box cupling 2 middle inside circumferencial directions are provided with T shape boss 11, and promptly T shape boss 11 is by protruding to inside between last pump barrel 3 bottoms and standing valve 1 top.Described standing valve 1 top is provided with supporting frame 4, and supporting frame 4 tops are threaded with salvagable valve 7, and supporting frame 4 lower end exterior periphery directions are provided with the groove that matches with T shape boss 11; The groove bottom is provided with fixed claw 12; Fixed claw 12 can along the circumferential direction be uniformly distributed with for two or three, and the plane is provided with liquid outlet opening groove 10 on the liquid outlet opening on described salvagable valve 7 tops; Described liquid outlet opening groove 10 matches with fixed claw 12; Fixed claw 12 can insert in the liquid outlet opening groove 10 like this, fixes standing valve 1 at circumferencial direction, to prevent standing valve 1 rotation.Be provided with seal ring 6 between described salvagable standing valve 7 outsides and the last pump barrel 8.
Described salvagable valve 7 tops are connected with connecting rod 13; Connecting rod 13 excircles have the outside thread that matches with the internal thread of plunger 9 bottoms; Can salvagable valve 7 and supporting frame 4 together be connected plunger 9 bottoms, connecting rod 13 exterior circumferential are provided with groove, and groove top forms salvages shoulder 15.This hydraulic self-sealed plunger oil-well pump also comprises fishing head 14, and described fishing head 14 bottoms are provided with to projecting inward bailer grab 16, and described bailer grab 16 matches with salvaging shoulder 15.
This oil well pump is when starting working; Salvagable valve 7 and supporting frame 4 can be installed; When this oil well pump can not work on owing to reasons such as wearing and tearing, salvagable standing valve 7 and supporting frame 4 are connected in the plunger 9 bottom lower going-into-wells through connecting rod 13, the fixed claw 12 of supporting frame 4 bottoms inserts in the liquid outlet opening groove 10; And match with T shape boss 11, rotate under the effect of peripheral force to prevent salvagable standing valve 7.Sealing between salvagable standing valve 7 and the last pump barrel 8, plunger 9 can continue to work on for 8 sections at last pump barrel like this, has saved to remove the time that oil pipe changes pump barrel, has prolonged the working life of oil well pump greatly.When the screw thread on the salvagable standing valve 7 because reason such as wearing and tearing can not be connected with plunger 9 time, can be lowered to subsequent use fishing head 14, the bailer grab 16 through fishing head 14 bottoms and the salvaging shoulder 15 on the connecting rod 13 tops incompatible salvaging salvagable standing valve 7 that matches.
