Description
Technical field:
The utility model relates to the used oil well blowout hookup of operation in the oil recovery field, oil field, belongs to a kind of preventer.
Background technology:
In oil recovery field, oil field, because the pressure height of Oil, Water, Gas usually can spray along tubing string in the stratum, blowout hookup is installed usually in the down-hole like this, and present blowout hookup is with dowel fixes one plug in the sealing shroud bottom, break pin with water under high pressure after being lowered to sealing shroud, must suppress with the high pressure pump truck during installation and just can make plug fall into the shaft bottom, inconvenience is installed; It can only disposablely use simultaneously, can not use repeatedly; In addition, can't prevent blowout when sealing shroud is extracted in operation, not only having caused wastes but also contaminated environment.
The utility model content:
In order to solve existing blowout hookup inconvenience is installed, can not uses repeatedly and the deficiency of blowout prevention weak effect, the utility model provides a kind of preventer, and that this preventer has is easy for installation, can use repeatedly and the blowout prevention good effectiveness.
The technical solution of the utility model is: this preventer comprises sealing shroud and lower contact, sealing shroud inwall and lower end be fixed band plug and the piston bush of built-in piston and the transit joint of built-in lower contact respectively, some chutes mutually sliding block of transit joint by having in pin and the lower contact; Piston bush openend sidewall has through hole; Piston links to each other with connecting rod by the cap that is equipped with holes, and the other end of connecting rod is fixed with the connecting rod base that links to each other with lower contact and be with oil-through hole.
It between above-mentioned piston and the piston bush matched in clearance; Chute evenly distributes 4 along the lower contact circumferencial direction.
The utlity model has following beneficial effect: owing to take the piston bush of the fixing built-in piston of sealing shroud inwall in the such scheme, the piston bush sidewall has through hole, piston links to each other with the connecting rod that is connected in lower contact, instantly oil pipe or when playing oil pipe, be connected with devices such as screen casing under the lower contact, making lower contact drive piston under action of gravity moves downward, and then the through hole of piston bush sidewall is stopped up, no matter following oil pipe still plays the purpose that oil pipe all can reach blowout prevention, blowout prevention is effective, when being installed, oil pipe needn't suppress with pump truck, and easy for installation; Owing to have chute in the lower contact and, it can only be slided up and down by the sliding mutually card of pin and transit joint, can not rotate, after being lowered to sealing shroud, needn't destroy its structure and can use, so this preventer can use repeatedly.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model.
1-sealing shroud among the figure, the 2-lower contact, the 3-piston bush, the 4-transit joint, the 5-through hole, the 6-piston, 7-is equipped with cap, 8-connecting rod, 9-connecting rod base, 10-pin, 11-oil-through hole, 12-plug, 13-chute.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this preventer comprises sealing shroud 1 and lower contact 2, and sealing shroud 1 inwall and lower end be fixed piston cover 3 and transit joint 4 respectively, piston bush 3 one end band plug 12 and built-in pistons 6, be matched in clearance between piston 6 and the piston bush 3, piston 6 can slide in piston bush 3 and sealing with it; Transit joint 4 is built-in with lower contact 2, the chute 13 mutually sliding card of transit joint 4 by having in pin 10 and the lower contact 2, and chute 13 evenly distributes 4 along lower contact 2 circumferencial directions, and piston bush 3 openend sidewalls have through hole 5; Piston 6 links to each other with connecting rod 8 by the cap 7 that is equipped with holes, and the other end of connecting rod 8 is fixed with the connecting rod base 9 that links to each other with lower contact 2 and be with oil-through hole 11; Instantly oil pipe or when playing oil pipe, lower contact is connected with devices such as oil pump for 2 times, making lower contact 2 drive piston 6 under action of gravity moves downward, and then the through hole 5 of piston bush 3 sidewalls is stopped up, no matter following oil pipe still plays the purpose that oil pipe all can reach blowout prevention, blowout prevention is effective, needn't suppress with pump truck when oil pipe is installed, and is easy for installation; Owing to have chute 13 in the lower contact 2 and, it can only be slided up and down by the sliding mutually card of pin and transit joint, can not rotate, after being lowered to sealing shroud 1, needn't destroy its structure and can use, so this preventer can use repeatedly.
Claims (3)
