Abstract
A kind of air operated slips seat, it is taper cone barrel in pedestal, upper end bore is big, lower end bore is small, for installing slips, there is disk on the top of pedestal, for supporting pneumatic means, there is ring flange in the bottom of pedestal, 28 bolts hole are uniformly arranged on described ring flange, self-sealing core catching groove is opened up in the bottom surface of described ring flange, the shape and size of described self-sealing core catching groove are identical with the shape and size of supporting self-sealing core, the utility model has the function of air operated slips seat and self-sealing core gland, the part and height of wellhead assembly can be reduced, so as to reduce equipment cost, also can convenient construction operation, with significant economic benefit and social benefit.
Description
Technical field
The utility model belongs to the mechanical device of oil well, the corollary equipment of wellhead assembly when being well workover, tool
Body is a kind of air operated slips seat.
Background technology
Oil field goes out lower oil pipe in well to put to ground in workover treatment from well, during lower oil tube, mesh
Before the operation well that has begin to use air operated slips to replace pipe elevator to carry out oil pipe tripping operation.Because it is not required to air operated slips
Elevator is manually won, can be reduced labor intensity, improves operating efficiency.In workover treatment is automated, air operated slips is also
The essential operation corollary equipment of lower oil tube.During lower oil tube, self-sealing device to be also installed under air operated slips,
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 to be installed in well head
Self-sealing device.Self-sealing core in self-sealing device is clasped by the gland on self-sealing device, prevents self-sealing core from play.Therefore, with pneumatic
The wellhead assembly of slips lower oil tube operation is：Independent air operated slips, independent self-sealing device, preventer, wellhead assembly are from upper
Installed successively under.The wellhead assembly part of this lower oil tube operation is more, and well head height is high, one side wellhead equipment cost
Height, another aspect operation are inconvenient.
The content of the invention
The purpose of this utility model is a kind of air operated slips seat of design, it is overcome above-mentioned problem, makes pneumatic clamping
Watt seat tool has the function of self-sealing device gland, reduces the part and height of wellhead assembly.
What the purpose of this utility model was realized in：It is taper cone barrel in pedestal, upper end bore is big, and lower end bore is small, uses
In installation slips, there is disk on the top of pedestal, for supporting pneumatic means, have ring flange in the bottom of pedestal, described
2-8 bolt hole is uniformly arranged on ring flange, self-sealing core catching groove, described self-styled core are opened up in the bottom surface of described ring flange
The shape and size of sub-buckle groove are identical with the shape and size of supporting self-sealing core.
The beneficial effects of the utility model are：Open up self-sealing core catching groove in the bottom surface of described ring flange, it is described from
It is identical with the shape and size of supporting self-sealing core to seal the shape and size of fuse catching groove, makes the utility model that there is pneumatic clamping
The function of watt seat and self-sealing core gland, it is possible to reduce the part and height of wellhead assembly, also can be square so as to reduce equipment cost
Just construction operation, there is significant economic benefit and social benefit.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
Embodiment of the present utility model is illustrated with reference to Fig. 1.
As shown in figure 1, embodiment of the present utility model is as follows：It is taper cone barrel 1-2 in pedestal 1, upper end bore is big, lower port
Footpath is small, for installing slips, has disk 1-1 on the top of pedestal 1, for supporting pneumatic means, has flange in the bottom of pedestal 1
Disk 1-3, it is uniformly arranged on described ring flange 1-3 multiple（2-8）Bolt hole 1-4, in described ring flange 1-3 bottom surface
Open up self-sealing core catching groove 1-5, the shape of described self-sealing core catching groove 1-5 shape and size and supporting self-sealing core and
Size is identical.
Self-sealing device is arranged on blowout preventer during use, is put into after the fuse of self-sealing device is sleeved on oil pipe in self-sealing device,
The utility model being sleeved on oil pipe is clasped to the fuse of self-sealing device again, the fuse of self-sealing device is worn from play with bolt
The bolt hole by bolt hole 1-4 and blowout preventer is crossed, the utility model is linked into an integrated entity with self-sealing device, it is possible to
Scraping is carried out to the greasy dirt on oil pipe surface during lower oil tube.
