Description
Technical field
The utility model belongs to the mechanical device of oil well, is a kind of self-styled well head for preventing greasy dirt to be scattering into ground
Device, specifically one kind can the self-styled wellhead assemblies of blowdown.
Background technology
Oil field, by OIH pipe from ground G.I.H, also goes out OIH pipe in workover treatment from well
Put to ground, in order to prevent ground object from falling into well, prevent oil-pipe external wall greasy dirt field to ground from causing environmental pollution, also simultaneously
Righting oil pipe is wanted, typically self-sealing well sealer to be installed in well head.Although the self-sealing core on current self-sealing device can be by oil-pipe external wall
On most greasy filth scrape and fall into well, but when tubing string is unable to draining（Tubing string bottom is not installed by bleeder, or bleeder
It can not open）, profit can be from the outflow of the inside of oil pipe upper end, and the outer wall through oil pipe flows downward, due to outer wall and oneself of oil pipe
Can not be by liquid stream between self-sealing core on envelope device, so the inside stream through oil pipe upper end goes out the passage that do not flow down, profit is only
It can fall on wellhead assembly, then fall earthward, cause wellhead assembly and operation field to be on the one hand not easy to operation by oily wastewater pollution
Construction, on the other hand pollute environment.Even if tubing string energy draining, profit is not flowed out inside the upper end of oil pipe, but in oil pipe and oil
When pipe box cupling junction passes through self-sealing device, some greasy filth can also be brought on wellhead assembly and fall earthward, and cause wellhead assembly
With operation field by oily wastewater pollution.
The content of the invention
The purpose of this utility model be design one kind can the self-styled wellhead assembly of blowdown, when bringing it about above mentioned problem, fluid
It can flow back into well, overcome the problem of presently, there are, avoid causing wellhead assembly and operation field by oily wastewater pollution.
What the purpose of this utility model was realized in：Including air operated slips seat, self-sealing core, blowout preventer, connecting bolt,
Oil pipe, self-sealing core are seated on the upper surface of blowout preventer, and air operated slips seat clasps self-sealing core, air operated slips seat interior energy installation gas
Dynamic slips, air operated slips seat are linked into an integrated entity with blowout preventer by connecting bolt, and oil pipe is self-styled through air operated slips seat, blowout preventer
The lower inner wall of fuse encases the outer wall of oil pipe, the internal diameter energy elastic dilatation of self-sealing core make the box cupling on oil pipe top by,
Cavity is set in the top of blowout preventer, and the bottom of self-sealing core is put into the described cavity of blowout preventer, set on self-sealing core
Put communication groove, described communication groove is in self-sealing core and encased on oil pipe position, make the inner chamber of air operated slips seat with it is described
Cavity UNICOM, the greasy dirt of the inner chamber of air operated slips seat can be flow under blowout preventer by described communication groove.
The beneficial effects of the utility model are：Communication groove is set on self-sealing core, is preventing ground object from falling into well,
While preventing that oil-pipe external wall greasy dirt field to ground from causing environmental pollution, moreover it is possible in the case of righting oil pipe, can make from oil pipe
The fluid of the inside outflow at end, or when passing through self-sealing device from oil pipe and tubing coupling junction, be brought on wellhead assembly
Greasy filth, then flow back into from described linked hole in well, blowdown is realized, avoids the greasy dirt from falling on wellhead assembly and wellsite,
Therefore, the utility model can reach purpose of design, overcome the problem of presently, there are, on the one hand can be in order to job execution, separately
On the one hand it can prevent from polluting environment, there is very strong practicality.
Brief description of the drawings
Fig. 1 is installation diagram of the present utility model.
Embodiment
Embodiment of the present utility model is illustrated with reference to Fig. 1.
As illustrated, embodiment of the present utility model includes air operated slips seat 1, self-sealing core 2, blowout preventer 3, connecting bolt
4th, oil pipe 5, self-sealing core 2 are seated on the upper surface of blowout preventer 3, and air operated slips seat 1 clasps self-sealing core 2, in air operated slips seat 1
Air operated slips can be installed, air operated slips seat 1 is linked into an integrated entity with blowout preventer 3 by connecting bolt 4, and oil pipe 5 passes through air operated slips seat
1st, blowout preventer 3, the lower inner wall of self-sealing core 2 encase the outer wall of oil pipe 5, and the internal diameter energy elastic dilatation of self-sealing core 2 makes oil pipe 5
The box cupling on top in the top of blowout preventer 3 by setting cavity 7, the bottom of self-sealing core 2 is put into the described of blowout preventer 3
In cavity 7, this design can reduce total height of the present utility model, and communication groove 6, described connection are set on self-sealing core 2
Groove 6 is in self-sealing core 2 and encased on the position of oil pipe 5, makes inner chamber and the described UNICOM of cavity 7, the gas of air operated slips seat 1
The greasy dirt of the inner chamber of dynamic slip spider 1 can be flow under blowout preventer 3 by described communication groove 6.
Communication groove 6 on self-sealing core 3 opens up 2-6, and the width of communication groove 6 increases as far as possible in the case of proof strength
Greatly, make its unblocked.
The lower end of blowout preventer 3 is connected with wellhead assembly during use.Air operated slips seat 1 is structure as a whole, in order to reduce cost
Or it is easy to processing to be processed into sub-assembly.
Bottom, self-sealing core 2, the top of blowout preventer 3 of air operated slips seat 1 constitute self-sealing device, make its wellhead assembly simple
Change, it is easy to use.
