Abstract
The utility model relates to a rubber sleeve protection device of a packer. The rubber sleeve protection device of the packer comprises a sliding groove base, a sliding block, a cone body, an outer protection bowl and an inner protection bowl, wherein the inner protection bowl, the outer protection bowl, the cone body, the sliding block and the sliding groove base are installed at the two ends of a rubber sleeve of the packer and sequentially installed outwards from one end of the rubber sleeve. The inner protection bowl and the outer protection bowl are respectively provided with at least six axial kerfs. One surface of the outer protection bowl is overlaid with the inner protection bowl, and the other surface of the outer protection bowl is attached to the cone body. An outer conical surface is arranged on the outer wall of the cone body, and the outer conical surface of the cone body and an inner conical surface arranged on the inner wall of one side of the sliding block are installed in a matching mode. At least ten guide heads are arranged on the other side of the sliding block along the circumference, grooves of the corresponding number are formed in the circumference of one side of the sliding groove base, and the guide heads are installed in the grooves correspondingly. According to the technical scheme, the rubber sleeve protection device of the packer has the advantages that the shoulder protrusion phenomenon of the rubber sleeve of the packer can be prevented effectively, the pressure bearing capacity of the rubber sleeve is improved, and the use requirement when the packer is used under the high pressure environment can be met.
Description
Technical field
The utility model relates to and a kind ofly is arranged on the packing element two ends, be used to preventing packing element, occurs that shoulder is prominent, device protection packing element functional performance, specifically a kind of protective device for packer rubber tube when the packer setting.
Background technology
Packer is a kind of between packing tubing string and well and the downhole tool of the annular space between tubing string, and packing element is the element of most critical in packer.In process of production, the operting differential pressure that the upper and lower end of packing element bears is a kind of fluctuating load, the axial compressive force that operting differential pressure forms is much larger than seating sealing load, packing element will be further compressed, the packing element shoulder will flow to the annular space between Pressure Block and sleeve pipe, make the outstanding distortion aggravation of packing element shoulder, significantly reduce the sealing performance of packer.At present, oil-water well requires more and more higher to the functional performance of packer, how to prevent that packing element from producing shoulder performance prominent, that the improve packing element ever more important that seems.
The utility model content
The purpose of this utility model is to provide a kind of protective device that the packing element shoulder is dashed forward that prevents of dependable performance, to meet the bearing requirements of packer in various hole conditions.
For achieving the above object, the utility model provides a kind of protective device for packer rubber tube, comprise sliding chute seat, slide block, cone, outward protect bowl, in protect bowl, and be arranged on the two ends of packing element on packer, by packing element one end, outwards installed successively: inside protect bowl, protect bowl, cone, slide block, sliding chute seat outward; Wherein, inside protect bowl, protect on bowl and be respectively equipped with at least six axial slots outward, protect outward bowl one side and in protect bowl stack; Protect another side and the cone of bowl outward and be close to, the outer wall of described cone is with male cone (strobilus masculinus), and the inner conical surface that the male cone (strobilus masculinus) of described cone and slide block one side inwall are provided with coordinates to be installed; The opposite side of described slide block is provided with at least ten guide heads along circumference, and on sliding chute seat one side circumference, with the groove of respective amount, described guide head correspondence is arranged in described groove.
Wherein, two sides of the groove on described sliding chute seat are parallel to each other.
Wherein, the inner conical surface of described slide block is consistent with the fit angle of the male cone (strobilus masculinus) of cone.
Wherein, the garter spring hoop is in the rectangular channel that described slide block outer wall is provided with.
Wherein, stagger mutually angle more than 5 ° of the slot that inside protects bowl and protect bowl outward.
The beneficial effect of the technical scheme that the utility model provides is: the shoulder that can effectively prevent packing element is appeared suddenly and is resembled, and improves the bearing capacity of packing element, meets the instructions for use of packer under hyperbaric environment.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of sliding chute seat.
Fig. 3 is the structural representation of slide block.
Fig. 4 is for protecting the structural representation of bowl outward.
Fig. 5 protects the structural representation of bowl in being.
In figure: 1 is sliding chute seat, and 2 is slide block, and 3 is garter spring, and 4 is cone, and 5 for protecting bowl outward, and 6 protect bowl in being, 7 is groove, and 8 is guide head, and 9 is slot.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and effect clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.During use, the utility model is arranged on to the two ends of packing element.During packer setting, under Axial Loads, cone 4 produces relative motion with sliding chute seat 1, and the guide head 8 of slide block 2 radially outwards slides in the groove 7 of sliding chute seat 1, until be close to sleeve pipe or open hole well inwall.In the process that slide block 2 radially outwards slides, garter spring 3 is pulled off, and slide block 2 is released; Meanwhile, packing element axially is compressed and radially produces expansion, makes to produce enough contacts, the annular space between sealing oil pipe and pit shaft between packing element and pit shaft.Inside protect bowl 6 softened because of the extruding that is subjected to packing element; Protect bowl 5 outward softened due to the extruding of protecting bowl 6 in being subjected to; final outer protecting on the inner conical surface that bowl 5 is close to the slide block 2 that distributes along even circumferential; inside protecting bowl 6 is close on the inner surface that protects bowl 5 outward; stop that the packing element shoulder continues outwards to expand; avoid the packing element shoulder to appear the generation of elephant suddenly, thereby reach the purpose of protection packing element, raising packer withstand voltage properties.
Wherein, in the rectangular channel of described garter spring 3 hoops on slide block 2 excircles, anti-limited slip block 2 is in advance from the interior slippage of groove 7 of sliding chute seat 1.
Wherein, guide head 8 is contained in the groove 7 of sliding chute seat 1, and can in groove 7, radially slide;
Above-described is only better possible embodiments of the present utility model; described embodiment is not in order to limit scope of patent protection of the present utility model; therefore the equivalent structure done of every utilization manual of the present utility model and accompanying drawing content changes, within like manner all should being included in protection domain of the present utility model.
