Description
Technical field
This utility model is the device of a kind of oil extraction in oil field well head, be a kind of under blowout prevention blowout preventer under well head.
Background technology
Oil field gas injection thermal production well noted high pressure-temperature steam turn take out time, need change wellhead tree tree, now wellhead equipment is removed, well head is in opening-wide state, well head does not control equipment, after borehole pressure recovers, and borehole pressure superatmospheric power, easily happen suddenly blowout, major accident occurs, thus oil field gas injection thermal production well exists potential potential safety hazard when changing well head, and blowout once occurs, easily cause into personnel's injury accident, need to put into substantial amounts of resource of speedily carrying out rescue work.Once there is blowout, will also result in crude oil and run off, also pollute the environment, cause heavy economic losses.
Summary of the invention
The purpose of this utility model be design a kind of under blowout prevention blowout preventer under well head, oil field gas injection thermal production well is when changing well head, and borehole pressure is controlled, it is to avoid the generation of the problems referred to above, it is to avoid personnel's injury and economic loss.
The purpose of this utility model is achieved in that and includes inner tube, rotary anchoring device, slips support, slips, cone, packing element, glue tube base, slips support, cone, packing element is sleeved on outside inner tube, slips is installed between slips support and cone, the upper suspension of slips is in slips support, the bottom of slips reaches in the slip groove being connected on cone, the taper surface of slips contacts with the taper surface cooperation of cone, glue tube base is installed in the bottom of packing element, glue tube base connects on inner pipe, screw thread is pulled in inner tube, the female thread of rotary anchoring device pulls threaded engagement with described, the bottom of rotary anchoring device is connected with the top of slips support, rotary anchoring device can precession on inner pipe.
Cone links into an integrated entity with packing element, and the bottom of packing element is conical bore, and the top of glue tube base is cone, and described conical bore is fitted together with described conical sleeve.
nullThe beneficial effects of the utility model are: this utility model is arranged in the sleeve pipe under the well head of oil field gas injection thermal production well，At ground rotating inner tube，Rotary anchoring device is anchored on sleeve pipe，The strong point is become after making it motionless，Continue rotating inner tube，Under pulling threaded function，Inner tube is upwards walked，First the Distance Shortened between slips support and cone is made，Under the taper surface effect of cone，Slips is pushed out card jail on sleeve pipe，Continue rotating inner tube，Inner tube continues up walking，Glue tube base compression packing element，Packing element expansion is made to seal up sleeve pipe，The liquid stream having pressure in making well can not erupt to ground，Surface well port part does not has pressure，Replacing that can be safe turns takes out wellhead assembly，Blowout will not occur，Overcome the potential safety hazard that presently, there are，Generation personnel's injury accident and heavy economic losses can be avoided，There is significant economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is the installation diagram of this utility model embodiment.
Detailed description of the invention
Below in conjunction with Fig. 1, this utility model embodiment is illustrated.
nullAs shown in Figure 1，Example of executing of the present utility model includes inner tube 1、Rotary anchoring device 2、Slips support 3、Slips 4、Cone 5、Packing element 6、Glue tube base 7，Slips support 3、Cone 5、Packing element 6 is sleeved on outside inner tube 1，Slips 4 is installed between slips support 3 and cone 5，The upper suspension of slips 4 is in slips support 3，Slips 4 can be displaced outwardly，But will not come off from slips support 3，The bottom of slips 4 reaches in the slip groove being connected on cone 5，The taper surface of slips 4 contacts with the taper surface cooperation of cone 5，Slips 4 can be walked in described slip groove，Just (identical with the structure of packer) is not come off，Glue tube base 7 is installed in the bottom of packing element 6，Glue tube base 7 is connected in inner tube 1，Screw thread 8 is pulled in inner tube 1，The female thread of rotary anchoring device 2 screws with the described screw thread 8 that pulls，The bottom of rotary anchoring device 2 is connected with the top of slips support 3，Rotary anchoring device 2 can precession in inner tube 1.Cone 5 links into an integrated entity with packing element 6, and the bottom of packing element 6 is conical bore, and the top of glue tube base 7 is cone, and described conical bore is fitted together with described conical sleeve, and glue tube base 7 contract enters in packing element 6, makes packing element 6 be easier to dilatating and deformable.
Rotary anchoring device 2 is existing matured product, and rotary anchoring device 2 is also referred to as turnover panel anchor by scene.
This utility model is arranged in the sleeve pipe under the well head of oil field gas injection thermal production well, at ground rotating inner tube 1, rotary anchoring device 2 is anchored on sleeve pipe, the strong point is become after making it motionless, continue rotating inner tube 1, under the effect pulling screw thread 8, inner tube 1 is upwards walked, first the Distance Shortened between slips support 3 and cone 5 is made, under the taper surface effect of cone 5, slips 4 is pushed out card jail on sleeve pipe, continue rotating inner tube 1, inner tube 1 continues up walking, glue tube base 7 compresses packing element 6, packing element 6 expansion is made to seal up sleeve pipe, the liquid stream having pressure in making well can not erupt to ground.
