Abstract
Of the present utility modelly relate to a kind of deep-well or ultradeep well boll-weevil hanger, it comprises body, offers female joint in body upper end, and lower end is communicated with clamping part, and male joint is offered in clamping part bottom.Hang shoulder under clamping part and body connectivity part outside are formed, the body on lower suspension shoulder top arranges suspension shoulder, body upper part is provided with seal groove.The application's structure is simple, not only can solve clip and hold problem, prevent torque wrench moment from affecting oil connection bonding strength not, and structure is simple, and execute-in-place is convenient, significantly improves security reliability and the application life of well head.Devising boll-weevil hanger structure upper end is female joint, and lower end is male joint, solves existing boll-weevil hanger lower end and double male joint connectivity problem, and this structure does not need to adopt double male joint, directly can be connected with finished product oil pipe.
Description
Technical field
The utility model relates to a kind of oil recovery gas wellhead equipment.Particularly relate to a kind of deep-well or ultradeep well boll-weevil hanger.
Background technology
Tubing head is made up of oil pipe four-way and boll-weevil hanger, and boll-weevil hanger is sitting in the intrinsic cone seat of oil pipe four-way, is used for hanging tubing string, and between hung oil pipe and oil pipe four-way body, provide a kind of device of sealing.Boll-weevil hanger is in well head position, carries whole tubing string, and it is maximum that it bears tensile load, and operating mode is the harshest.The upper and lower two ends of boll-weevil hanger of prior art oil and gas wells in oil fields application are female joint, are connected with the oil pipe male joint be connected.When the female joint of boll-weevil hanger lower end is connected with the oil pipe male joint be connected, because boll-weevil hanger is shorter, tubing tongs cannot be adopted to carry out upper button to it, only carry out hand-tight in most cases.For deep & ultra-deep well, the tensile load that well head position is born is maximum, and only hand-tight upper button affects joint bonding strength, and the well head Joint failure caused due to moment of torsion deficiency is catastrophic, and repeatedly accident has occurred at scene, causes great economic loss.Therefore, in order to strengthen the bonding strength of well mouth oil pipe hanger, improve well head safe reliability, in the urgent need to a kind of deep & ultra-deep well boll-weevil hanger structure, be applicable to deep & ultra-deep well security needs, substitute the boll-weevil hanger that the common two ends used at present are female joint, there is technical barrier to solve it.
Summary of the invention
The purpose of this utility model is on the basis analyzing existing boll-weevil hanger design feature, for its weak point, provides a kind of and facilitates execute-in-place and meet the deep-well or ultradeep well boll-weevil hanger of tubing tongs being detained needs.
The purpose of this utility model is achieved in that deep-well or ultradeep well boll-weevil hanger, and it comprises body, offers female joint in body upper end, and lower end is communicated with clamping part, and male joint is offered in clamping part bottom.Hang shoulder under clamping part and body connectivity part outside are formed, the body on lower suspension shoulder top arranges suspension shoulder, body upper part is provided with seal groove.
Owing to carrying out technique scheme, the application's structure is simple, not only can solve clip and hold problem, prevent torque wrench moment from affecting oil connection bonding strength not, and structure is simple, execute-in-place is convenient, significantly improves security reliability and the application life of well head.Devising boll-weevil hanger structure upper end is female joint, and lower end is male joint, solves existing boll-weevil hanger lower end and double male joint connectivity problem, and this structure does not need to adopt double male joint, directly can be connected with finished product oil pipe.
Accompanying drawing illustrates: the technical solution of the utility model is provided by following drawings and Examples:
Fig. 1 is deep-well or ultradeep well boll-weevil hanger structural representation.
Legend: 1, male joint, 2, clamping part, 3, lower suspension shoulder, 4, body, 5, upper suspension shoulder, 6, O shape ring recess, 7, seal groove, 8, sealing ring binding thread, 9, female joint.
Detailed description of the invention:
The utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, deep-well or ultradeep well boll-weevil hanger it comprise body 4, offer female joint 9 in body 4 upper end, lower end is communicated with clamping part 2, and male joint 1 is offered in clamping part 2 bottom.Clamping part 2 and body 4 connectivity part outside form lower suspension shoulder 3, and the body 4 on lower suspension shoulder 3 top arranges suspension shoulder 5.Body 4 top is provided with seal groove 7, it is socketed sealing ring.Upper button retaining part 2 length is not less than 200mm.
Body 4 outer setting on the downside of aforementioned female joint 9 has sealing ring binding thread 8 outwardly, forms seal groove 7 between sealing ring binding thread 8 and upper suspension shoulder 5, and sealing ring binding thread 8 spins fastening nut.
Described upper suspension shoulder 5 is back taper.
Upper and lower suspension shoulder 5,3 offers O shape ring recess 6, socket O shape circle in it.
During use, male and female joint 1,9 can directly spin with oil pipe male and female joint respectively, turns clamping part 2 carry out upper button by tubing tongs, solve while clip holds problem, cancel the structure that existing boll-weevil hanger lower end is connected with double male joint, reduce and use parts, reduce and damage possibility.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
