Description
Technical field
The utility model relates to the sealing device of oil-water well workover treatment well head, specifically the clean protective device of a kind of mechanization workover treatment tubing string.
Background technology
At present, when hydraulic oil well is carried out to mechanization workover treatment, if there is overflow to occur, overflow meeting causes damage to bank head machinery equipment, therefore needs the clean protective device of tubing string to prevent the generation of overflow.Because the clean protective device of existing tubing string exists use cost high, inconvenient operation, the shortcoming such as application life is low, is badly in need of that invention is a kind of can be met the clean protection of oil-water well mechanization workover treatment tubing string and require to facilitate again workman to operate the device of use.
Summary of the invention
The purpose of this utility model is to provide a kind of mechanization workover treatment tubing string to clean protective device; utilize this device can effectively realize tubing string sealing in oil-water well workover treatment process; the self-styled clean seal of guaranteeing conventional tubing string, annular preventer is guaranteed the clean seal of instrument.
In order to reach above-mentioned purpose; the utility model has adopted following technical scheme; a kind of mechanization workover treatment tubing string cleans protective device; comprise self-sealing rubber core, annular preventer; described self-sealing rubber core is fixed in annular preventer upper shed; described self-sealing rubber core center is offered middle through hole and is led to annular preventer lower lumen, and described middle through hole middle and lower part is primary seal section.
Described self-sealing rubber core upper end arranged outside annulus Ka Tai is also fastened on outer, annular preventer upper shed upper end, above described annular preventer, arrange be used for compressing self-sealing rubber core from sealed cover, the described middle through hole of offering from sealed cover center with described self-sealing rubber core connects passes through hole.
Describedly from sealed cover, by connecting bolt, be fixed on above annular preventer, described self-sealing rubber core and sealing ring is set between sealed cover, is also provided with sealing ring between self-sealing rubber core and annular preventer.
In described self-sealing rubber core, the medial surface at the upper and lower two ends of through hole is all designed to conical guide section, and large mouthful of the guide section of described upper end is upper, large mouthful of the guide section of described lower end under.
The middle through hole middle part of described primary seal section top sets gradually little groove section, big groove section from top to bottom.
Compared to prior art, the utlity model has following beneficial effect:
1, utilize this device can effectively realize the clean seal of tubing string in oil-water well workover treatment process, the self-styled clean seal of guaranteeing conventional tubing string, annular preventer is guaranteed the clean seal of instrument.
2, the built-in hermetically-sealed construction of self-sealing rubber core, reduces cleaning sealing device whole height, and workman is easy to operate.
3, as need, change self-sealing rubber core, gland is opened to replacing, workable.
4, self-sealing rubber core, by the design of guide section, groove section, makes the application life of glue core elongated, and operating cost reduces.
Accompanying drawing explanation
Fig. 1 is the structure chart of the clean protective device of a kind of mechanization workover treatment tubing string of the present utility model.
In figure: from sealed cover 1, connecting bolt 2, self-sealing rubber core 3, annular preventer 4, little groove section 5, big groove section 6, guide section 7, guide section 8.
The specific embodiment
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, yet accompanying drawing only provides the use of reference with explanation, is not used for the utility model to be limited.
As shown in Figure 1; a kind of mechanization workover treatment tubing string cleans protective device; comprise self-sealing rubber core 3, annular preventer 4; described self-sealing rubber core is fixed in annular preventer upper shed; described self-sealing rubber core center is offered middle through hole and is led to annular preventer lower lumen, and described middle through hole middle and lower part is primary seal section 9.Described self-sealing rubber core upper end arranged outside annulus Ka Tai is also fastened on outer, annular preventer upper shed upper end, above described annular preventer, arrange be used for compressing self-sealing rubber core from sealed cover 1, the described middle through hole of offering from sealed cover center with described self-sealing rubber core connects passes through hole.Describedly from sealed cover, by connecting bolt 2, be fixed on above annular preventer, described self-sealing rubber core and sealing ring is set between sealed cover, is also provided with sealing ring between self-sealing rubber core and annular preventer.In described self-sealing rubber core, the medial surface at the upper and lower two ends of through hole is all designed to conical guide section, and large mouthful of the guide section of described upper end 8 is upper, large mouthful of the guide section 7 of described lower end under.The middle through hole middle part of described primary seal section top sets gradually little groove section 5, big groove section 6 from top to bottom.
The housing of high-pressure self-sealing is flange-type structure, is connected by bolt 2 with annular preventer 4, and high-pressure self-sealing glue core 3 bottoms are built in the enclosure interior upper end position of ring seal preventer 4.Self-sealing rubber core is divided into 9,4 little groove sections 5 of primary seal section, big groove section 6, guide section 7 and 8.
In carrying out oil-water well mechanization workover treatment process; the annular preventer of the clean protective device of this tubing string is coordinated and is installed to operation wellhead with other wellhead equipments; by annular preventer, seal and trip out well mouth hanger; in annular preventer upper interior, self-sealing rubber core is installed; by bolt, will link together from sealed cover and annular preventer, seal lower tubular column.In sealing tubing string process, primary seal section 9 plays the effect of main sealing; 4 little groove sections 5 are alleviated the wearing and tearing of tubing string to glue core; Groove section 6 plays the effect of pressure buffer; Guide section 7 and 8 plays guide effect, avoids the wearing and tearing of tubing string to glue core.In use procedure, if there is glue core, damage phenomenon, take away from sealed cover, take out the glue core of damaging, change virgin rubber core.
The foregoing is only preferred embodiment of the present utility model, non-in order to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
