Description
Technical field
The utility model relates to boll-weevil hanger, is specifically related to a kind of two spacing metal sealing boll-weevil hanger.
Background technology
At present, there is following problem in known metal sealing boll-weevil hanger:
1. upper metal sealing ring and the lower metal sealing ring magnitude of interference not separate, total magnitude of interference of upper and lower metal sealing is fixed, but the magnitude of interference of metal o-ring cannot independently control up and down, during use, because the size of upper and lower metal o-ring is different, decrement by two kinds of metal o-rings during identical power is different, and the sealing reliability of twice metal o-ring has no idea to assess and control;
2. the location of boll-weevil hanger relies on the metal o-ring magnitude of interference to control, once well head being under pressure, the impact of the effect such as temperature, can there is a little displacement in boll-weevil hanger, cause metal sealing to lose efficacy.
Summary of the invention
The purpose of this utility model is: provide a kind of two spacing metal sealing boll-weevil hanger, realize: 1. the magnitude of interference of the metal sealing up and down of boll-weevil hanger is independently controlled, avoid the situation that the magnitude of interference of upper and lower two metal o-rings of boll-weevil hanger cannot independently control; 2. rigidity is all adopted to locate the location between boll-weevil hanger and four-way body, oil pipe four-way upper flange, do not rely on the metal o-ring magnitude of interference to realize and support and location, even if when the effects such as well head is being under pressure like this, temperature, boll-weevil hanger also can not produce any displacement, can not affect the sealing performance of boll-weevil hanger.
The scheme of technical solution problem of the present utility model is: this pair of spacing metal sealing boll-weevil hanger comprises oil pipe four-way upper flange, boll-weevil hanger body, upper metal o-ring, top FS type rubber seal, plug, jackscrew, bottom FS type rubber seal, lower metal o-ring, sealing ring backing ring, locking nut, check screw and oil pipe four-way, the inner chamber of oil pipe four-way establishes a spacing shoulder and No. two spacing shoulders, upper metal sealing ring, top FS type rubber seal, bottom FS type metal o-ring and plug are arranged on boll-weevil hanger body, lower metal sealing ring is arranged on boll-weevil hanger body by sealing ring backing ring and locking nut screw thread, locking nut is fixed on boll-weevil hanger body by check screw, boll-weevil hanger body is arranged on oil pipe four-way inside stably and tightens jackscrew, oil pipe four-way is tightened installation oil pipe four-way upper flange and excite boll-weevil hanger metal sealing, sealing ring backing ring just touches with oil pipe four-way inner chamber limiting stand shoulder grafting, lower metal sealing ring also touches with oil pipe four-way inner chamber No. two limiting stand shoulder graftings, forms dual rigid limit.
During assembling, first on boll-weevil hanger body, install top FS type rubber seal and bottom FS type rubber seal, then lower metal sealing ring, sealing ring backing ring, locking nut and check screw and plug are installed on boll-weevil hanger body successively, secondly the boll-weevil hanger assembled be installed to together with oil pipe assembly oil pipe four-way inside stably and tighten jackscrew, finally on boll-weevil hanger body, top metal o-ring is installed, oil pipe four-way is tightened installation oil pipe four-way upper flange and excite boll-weevil hanger metal sealing.
The utility model has the following advantages:
1. by the independent design of metal o-ring up and down of boll-weevil hanger, lower metal sealing ring relies on tightens jackscrew and tubing weight to excite metal sealing, upper metal sealing ring relies on the connecting bolt tightening oil pipe four-way upper flange to excite metal sealing, the situation that the magnitude of interference that this design prevents the metal o-ring up and down of boll-weevil hanger cannot independently control.
2. the location up and down of boll-weevil hanger is all designed to rigidity location, boll-weevil hanger is under the effect of jackscrew and tubing weight, deflection can deform through the lower metal o-ring of design, after metal sealing excites, sealing ring backing ring below metal o-ring just contacts with oil pipe four-way inner chamber shoulder, and the shoulder under boll-weevil hanger above metal o-ring also contacts with oil pipe four-way inner chamber shoulder, form dual rigid limit, boll-weevil hanger top is after metal sealing excites, boll-weevil hanger upper surface contacts with oil pipe four-way upper flange inner face, formation rigidity is located, this structure design is subject to temperature at well head, when the effects such as pressure, boll-weevil hanger can not produce any displacement, and sealing is very reliable.
3. can be used for super-pressure oil well, gas well, can meet under the temperature condition of-46 DEG C ~ 121 DEG C, apply rated operating pressure carry out high and low temperature circulation and realize sealing reliably, this structure tubing hanger hanger is oily under achieving field condition harsh conditions, the safe handling of gas well, greatly can improve the safety of well head while ensureing well head long-term production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 oil pipe four-way upper flange; 2 boll-weevil hanger bodies; Metal o-ring on 3; 4 top FS type rubber seal; 5 plugs; 6 jackscrews; 7 bottom FS type rubber seal; 8 times metal o-rings; 9 sealing ring backing rings; 10 locking nuts; 11 check screws; 12 oil pipe four-ways; No. 13 spacing shoulders; 14 No. two spacing shoulders.
