Abstract
The utility model relates to an anti-spurting device for well blowout disposal in workover treatment, in particular to an oil well anti-spurting device which can install wellhead flange plates on a wellhead when a blowout preventer fails. The oil well anti-spurting device is composed of a base, a hydraulic cylinder and a sleeve. When blowout happens, the blowout preventer is firstly turned off; meanwhile, a fixation pin bolt of the oil well anti-spurting device is taken down; a portal-frame-shaped assembly is erected to be vertical to the wellhead; the hydraulic cylinder is extended; a beam is lifted, and when an oil pipe plug top end is higher than an upper plane of a tubing coupling, a connection pin is taken down; and the beam continues to be lifted, and meanwhile a big flange plate drives an oil pipe plug and the like to slide downwards under the action of gravity and enables the oil pipe plug top end to point to an oil pipe opening. The oil well anti-spurting device has the advantages that mechanization is achieved when blowout wrecking is carried out, reliability is high, operators can operate far away from the wellhead on dangerous occasions, and personal safety of the operators is effectively protected.
Description
Affiliated technical field
Dispose the resistance spray apparatus of blowout when the utility model relates to a kind of workover treatment, especially can when preventer lost efficacy, be implemented in well head installing wellhead flange: oil well resistance spray apparatus.
Background technology
At present, the well control device that workover treatment generally is equipped with is manual single ram type perventer, when blowout takes place in order to sealing oil jacket annular space; But high-pressure fluid still can spray from oil pipe, and settling mode is to rob the outstanding plug of charge of oil pipe; When robbing dress, operating personnel can be can't bear by what oil, water drenched, particularly thermal production well; Oil pipe can spray high temperature oil, water, steam, more because the thermal expansion festival-gathering of thermal recovery tubing string hypomere sealing oil jacket annular space has played the effect of piston; Whole tubing string is sprayed from well head, even closed preventer this moment, tubing string also will exceed the height of an oil pipe of well head; Rob very difficulty of the outstanding plug of charge of oil pipe, in case on fire rob dress will become impossible.
Summary of the invention
Rob the outstanding problem of filling in inconvenience and thermal production well tubing string ejection well head of charge of oil pipe in order to solve present stage; The utility model has provided a kind of: oil pipe resistance spray apparatus; This oil pipe resistance spray apparatus can not only clog oil pipe, stop tubing string to rise, and can also when preventer lost efficacy, be implemented in well head installing wellhead flange.To achieve these goals, the utility model solves the technical scheme that its technical problem adopted and is: oil well resistance spray apparatus, by: base, hydraulic cylinder and sleeve are formed; It is characterized in that: jackscrew is housed on the base, and jackscrew is in order to be installed on base at preventer upper flange plate place, wherein: the interior diameter of base is identical with preventer upper flange plate diameter; Turning cylinder is equipped with at two ends at base, spacing ratchet respectively is housed on the turning cylinder and can rotates around it 90 degree hydraulic cylinders; The outside of hydraulic cylinder is with the sleeve that can slide along cylinder barrel, and wherein: sleeve design has fixed pin holes and moves about pin-and-hole, and a side of sleeve also is equipped with tooth bar; The cylinder barrel top of hydraulic cylinder has fixed pin holes, and the diameter jacking block identical with cylinder barrel is equipped with in the piston rod upper end, wherein: have the pin-and-hole that moves about on the jacking block; By locking nut lock crossbeam is arranged on the hydraulic cylinder piston rod top, wherein: through connecting pin open flow valve, big flange, oil pipe are installed in order on the crossbeam and revolve silk and tubing plug; On big flange, the lock dog that cooperates with tooth bar is housed.Before the workover treatment with the base sheath of this device on the preventer upper flange plate, make device be in the level state that couches, the adjustment orientation is a benefit not hinder operate as normal, fastening good jackscrew is accomplished installation.When blowout takes place, close preventer earlier, simultaneously; Take off the fixing pin of oil pipe resistance spray apparatus; Portal frame shape assembly is holded up into vertical well head state, and the elongation hydraulic cylinder rises and to take off connecting pin when crossbeam exceeds in the tubing coupling plane to the tubing plug tip; The crossbeam simultaneously big flange that continue to rise can drive tubing plug etc. to lower slider under action of gravity, and makes the most advanced and sophisticated sensing of tubing plug oil pipe mouth.After crossbeam is raised to suitable height, shrink hydraulic cylinder, it is descending that sleeve drives tooth bar, pushes away big flange under the tooth bar, and tubing plug is filled in oil pipe, at this moment, takes off the pin that moves about, and plugs fixing pin, accomplishes oil pipe resistance spray function.Lost efficacy or interim shut-in well like preventer, and can extend hydraulic cylinder this moment once more and arrive suitably height, between crossbeam and big flange, be encased inside sleeper, and shrank hydraulic cylinder big flange is depressed into the preventer upper flange plate, and loaded onto connecting bolt and get final product.
The beneficial effect of the utility model is, realizes mechanization when robbing spray, and reliability is high, and operating personnel can operate away from well head at hour of danger, effectively protects staff's personal safety.
