Abstract
The utility model relates to a kind of technical field of oil well workover, particularly a kind of tool joint sealing lining.This device adopts density to be less than 1.0g/cm
3polythene material make, sealing lining be designed to ring-type, this annular seal lining band has the tapering matched with tool joint pin thread.The utility model achieves and makes tool joint sealing become thread seal from end face seal, good sealing effect, and easy to use, low cost of manufacture, reduces the generation of well workover accident.Overcome the deficiency of existing tool joint sealing material sealing effect difference.
Description
Technical field:
The utility model relates to a kind of technical field of oil well workover, particularly a kind of tool joint sealing lining.
Background technique:
At present, in petroleum well workover operation, drilling tool is aging, and tool joint blow-by easily causes engineering accident.Repair this kind of drilling rod and need very large cost payout.And conventional seals glue (fat) class material seal poor effect, practical is poor.
Model utility content:
The technical problems to be solved in the utility model is to provide a kind of tool joint sealing lining, the arrangement achieves and makes tool joint sealing become thread seal from end face seal, good sealing effect, and easy to use, low cost of manufacture, reduces the generation of well workover accident.Overcome the deficiency of existing tool joint sealing material sealing effect difference.
Technical solution adopted in the utility model is: a kind of tool joint sealing lining, sealing lining adopts density to be less than 1.0g/cm
3polythene material make, sealing lining be designed to ring-type, this annular seal lining band has the tapering matched with tool joint pin thread.
The beneficial effects of the utility model are: the utility model makes tool joint sealing become thread seal from end face seal, good sealing effect, easy to use, and low cost of manufacture, reduces the generation of well workover accident.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in Figure 1, a kind of tool joint sealing lining, sealing lining adopts density to be less than 1.0g/cm
3polythene material make, sealing lining be designed to ring-type, this annular seal lining band has the tapering matched with tool joint pin thread.
It is 0.5mm, 1.0mm, 1.5mm tri-kinds of specifications that the utility model can make thickness.During use, the utility model is arranged between tool joint pin thread and box, tool joint is sealed and becomes thread seal from end face seal, good sealing effect, the utility model is single use, and chip of the present utility model can swim in the water surface because density is less than water, can not affect downhole tool.
Be understandable that, above about specific descriptions of the present utility model, the technological scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
