Abstract

The utility model relates to a novel oil well blowout prevention tubing drain, which mainly comprises an upper joint, a jacket, an elastic inner sliding sleeve and a lower joint, wherein the two ends of the jacket are respectively connected with the upper joint and the lower joint, a plurality of oil drain holes are arranged on the side wall of the jacket, the elastic inner sliding sleeve which is longitudinally provided with a plurality of grooves are arranged in an inner cavity, and the two ends of the elastic inner sliding sleeve are respectively provided with male joints, and are connected with male joints arranged on the inner ends of the upper joint and the lower joint. The outer wall of the elastic inner sliding sleeve can form an oil drain hole channel with the inner wall, the grooves and the oil drain holes of the jacket, and a plurality of sealing rings are arranged on the outer walls of the elastic sliding sleeve on the two sides of the oil drain holes to seal the oil drain holes when closing the tubing drain. The novel oil well blowout prevention tubing drain has the beneficial effects that the crude in oil pipe can be effectively prevented and controlled from blowing out when repairing oil wells or setting pumps, the environment pollution is reduced, and the work efficiency is improved, the safety production is guaranteed. In addition, the structure is simple, the operation is convenient and the service life is long.

Description

Novel oil well blowout prevention bleeder

One, technical field:

The utility model relates to a kind of oil well bleeder, the novel oil well blowout prevention bleeder that particularly a kind of reliability is high.

Two, background technology:

In the oil exploitation, by sleeve pipe and the down-hole oil tube of in the stratum, burying underground, and drive oil well pump with the sucker rod of oil pumper and extract, at this moment, bleeder is installed generally, is used for being communicated with oil pipe and sleeve pipe, and the oil in the oil pipe let out to well, when workover treatment, be not with crude oil or well liquid in the oil pipe, reduce the well site and pollute.The problem that exists is at present: through regular meeting the well head fuel injection event takes place, cause energy waste, influence job scheduling, cause construction dangerous, even serious security incident can take place.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of reliability high novel oil well blowout prevention bleeder, energy conservation, high efficiency, simple to operate and safe and reliable.

Its technical scheme is: mainly by top connection, overcoat, elasticity inner sliding sleeve and lower contact are formed, the two ends of described overcoat connect top connection and lower contact respectively, the sidewall of overcoat is provided with a plurality of drainings hole, described inner chamber is provided with the elasticity inner sliding sleeve of the many clamp bar slots of vertical distribution, the two ends of elasticity inner sliding sleeve are respectively equipped with female joint, with last, the male joint of the inner of lower contact connects, the outer wall of elasticity inner sliding sleeve and the inwall of overcoat, draw-in groove, the draining hole forms the draining passage, on the elasticity inner sliding sleeve outer wall of the both sides in draining hole, be provided with a plurality of sealing rings, can seal the draining hole when bleeder is closed.

Above-mentioned top connection and lower contact are respectively equipped with sealing ring and overcoat sealing.

The beneficial effects of the utility model are: during pump, can effectively prevent and control the crude oil ejection of oil pipe in well workover or under going into operation, reduce environment pollution, increase work efficiency, guarantee safety in production; In addition, it is simple in structure, easy to operate and long service life.

Four, description of drawings:

Accompanying drawing 1 is the structural representation of the utility model closed condition;

Among the last figure: top connection 1, sealing ring 2, sealing ring 3, elasticity inner sliding sleeve 4, sealing ring 5, overcoat 6, lower contact 7, draining hole 8, draw-in groove 9, female joint 10 and male joint 11.

Five, the specific embodiment:

In conjunction with the accompanying drawings 1, the utility model will be further described:

Its technical scheme is: its technical scheme is: mainly by top connection 1, sealing ring 2, sealing ring 3, elasticity inner sliding sleeve 4, sealing ring 5, overcoat 6, lower contact 7, draining hole 8, draw-in groove 9, female joint 10 and male joint 11 are formed, the two ends of described overcoat 6 connect top connection 1 and lower contact 7 respectively, the sidewall of overcoat is provided with a plurality of drainings hole 8, described inner chamber is provided with the elasticity inner sliding sleeve 4 of the many clamp bar slots 9 of vertical distribution, the two ends of elasticity inner sliding sleeve 4 are respectively equipped with female joint 10, with last, lower contact 1, the male joint 11 of the inner of 7 connects, the inwall of the outer wall of elasticity inner sliding sleeve 4 and overcoat 6, draw-in groove 9, draining hole 8 forms the draining passage, on elasticity inner sliding sleeve 4 outer walls of the both sides in draining hole 8, be provided with a plurality of

sealing rings

3,5, when being closed, bleeder can seal draining hole 8.

Above-mentioned top connection 1 and lower contact 7 are respectively equipped with sealing ring and overcoat 6 sealings.

The top connection of bleeder is connected with oil pipe, lower contact is connected with the oil well pump pump barrel, during operation, identical with common bleeder operation, after oil well pump and the oil pipe installation, G.I.H, under plunger rod, arrive the junction of oil pipe and oil well pump, the elasticity inner sliding sleeve of percussion bleeder, female joint 10 separates with male joint 11, bleeder will be closed automatically, with reference to accompanying drawing 1; When workover treatment needs draining, when promoting oil pump plunger piston, clash into the elasticity inner sliding sleeve again by sucker rod, bleeder will be opened automatically, reach the draining purpose.
