Abstract

The utility model relates to an oil draining device, in particular to a slide sleeve oil extracting and draining device. The technical scheme is that the slide sleeve oil extracting and draining device comprises an upper joint, a central pipe, an oil draining plug, an oil draining hole, an inner slide sleeve, a lower joint and a shearing-off dowel; the central pipe is connected in the upper and lower joints; the oil draining hole is formed in the outer part of the upper joint; the inner slide sleeve is arranged between the central pipe and the upper joint; a slide plate is arranged in the inner slide sleeve; the slide plate is fixed to the upper part of the upper joint by the shearing-off dowel. The slide sleeve oil extracting and draining device has the beneficial effects of ensuring the normal work of an oil draining device, realizing the normal oil draining function, reducing oil field loss and improving oil extraction efficiency.

Description

Sleeve type oil recovery bleeder
Technical field
The utility model relates to a kind of drainage device, particularly a kind of sleeve type oil recovery bleeder.
Background technology
At present, the bleeder that the pumpingh well of China Petroleum oil extraction system is used mainly contains hammering oil discharger, conventional hammering oil discharger unfolding mode is at present: the sucker rod in OIH pipe and piston are all proposed, the method of bar is thrown in employing from ground, the hollow pin of oil well pump bottom bleeder is severed and makes oil pipe be communicated with draining work with sleeve pipe; And that its deficiency has is following several: when sucker rod or piston occur disconnected when de-, in oil pipe, precipitate impurity that stratum goes out when too much, the nylon wiper block installed on sucker rod because of the normal phase in well, be subject to that high pressure and high temperature action cause efflorescence broken determine how out-of-date, all can cause cannot opening of bleeder.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of sleeve type oil recovery bleeder is provided.
Its technical scheme is: comprise top connection, central tube, oil drainer, draining hole, inner sliding sleeve, lower contact, cut off pin, top connection and the inner central tube that is connected of lower contact, described top connection outside is provided with draining hole, between central tube and top connection, be provided with inner sliding sleeve, in described inner sliding sleeve, be provided with slide plate, the top of top connection is by cutting off pin fixed sliding plate.
Between described slide plate and inner sliding sleeve, be provided with sealing ring.
The beneficial effects of the utility model are: guarantee the normal work of bleeder, realize normal oil draining function, reduce oil field loss, improve oil recovery efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: top connection 1, central tube 2, oil drainer 3, draining hole 4, inner sliding sleeve 5, lower contact 6, cut off pin 7, sealing ring 8, slide plate 9.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises top connection 1, central tube 2, oil drainer 3, draining hole 4, inner sliding sleeve 5, lower contact 6, cuts off pin 7, slide plate 9, top connection 1 and the inner central tube 2 that is connected of lower contact 6, the outside of described top connection 1 is provided with draining hole 4, oil drainer 3 is installed on draining hole 4, between central tube 2 and top connection 1, be provided with inner sliding sleeve 5, in described inner sliding sleeve 5, be provided with slide plate 9, the top of top connection 1 is by cutting off pin 7 fixed sliding plate 9.
Between described slide plate 9 and inner sliding sleeve 5, be provided with sealing ring 8.
During work, release head need be connected to the position of close plunger below of oil pumping rod centering device, before going into the well, can not clash into inner sliding sleeve with release head, avoids damage to cut off pin and makes inner sliding sleeve displacement, loses pressure-bearing function.Guarantee the normal work of bleeder, realize normal oil draining function, reduce oil field loss, improve oil recovery efficiency.
