Technical field
The utility model relates to the oil field and uses packing equipment, relates in particular to a kind of packing element shoulder protector anti-channeling anchor ring.
Background technology
At present, packer is a packing instrument commonly used in layering of oil gas well or the staged fracturing, and the bearing capacity of packer is concerning the success or failure that layering or segmentation are transformed.And packing element is the sealing unit of packer, how effectively to increase the bearing capacity of packing element, except improving the load performance of packing element itself, can also increase supporting mechanism at the packing element two ends.When packing element compressed, supporting mechanism can reduce or the ring type filling empty gap with the compression radial dilatation of packing element, prevents the packing element rheology, to improve the packing element bearing capacity; Simultaneously, after the packing element compression, have certain intensity, play the effect of supporting packing element, further improve the packing element bearing capacity.Supporting mechanism mainly comprises packer adapter, packing element, shoulder protector anchor ring positioning sleeve in the prior art; Packer adapter is sleeved on the packer central tube; Shoulder protector anchor ring positioning sleeve is threaded with packer adapter, and packing element is positioned at shoulder protector anchor ring positioning sleeve below and is socketed on the packer central tube, and shoulder protector anchor ring positioning sleeve and sleeve part leave certain annular space; So just exist the packing element top to have one to enclose the support that has no near the place of packing element; Along with the increase of packing element lower power members pressure, very easily make the packing element clamping stagnation on sleeve pipe, cause the packing element life-span to be reduced.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned technology, and a kind of packing element shoulder protector anti-channeling anchor ring is provided, and promotes the bearing capacity of packing element.
The utility model is for realizing above-mentioned purpose; Adopt following technical scheme: a kind of packing element shoulder protector anti-channeling anchor ring; Comprise packing element, shoulder protector anchor ring positioning sleeve; Said packing element is socketed on the packer central tube, and said shoulder protector anchor ring positioning sleeve is positioned at the packing element top and is fixedly mounted on the packer adapter, it is characterized in that: be provided with some packing element shoulder protector anti-channeling anchor rings and conical surface packing element spacer ring between said shoulder protector anchor ring positioning sleeve and packing element; The inward flange that said shoulder protector anchor ring positioning sleeve end opening is provided with, the outwardly-bent one-tenth groove in said packing element shoulder protector anti-channeling anchor ring top, the inward flange of said groove and shoulder protector anchor ring positioning sleeve end opening fastens, and said packing element shoulder protector anti-channeling anchor ring is axis swing with the inward flange; The cross section of said conical surface packing element spacer ring is trapezoidal, and the inclined-plane of the trapezoidal hypotenuse of this conical surface packing element spacer ring and packing element shoulder protector anti-channeling anchor ring bottom is slidingly matched.
The external surface of said packing element shoulder protector anti-channeling anchor ring is a zigzag.
Stud with bowl-shape return spring steel loop between said packing element shoulder protector anti-channeling anchor ring and the shoulder protector anchor ring positioning sleeve.
The top of said packing element shoulder protector anti-channeling anchor ring is provided with return glue ring.
The beneficial effect of the utility model is: the utility model is simple in structure; The up compression packing element of power part pressure-bearing on the packer; Conical surface packing element spacer ring is up along the packer central tube under the compressing of packing element; Force packing element shoulder protector anti-channeling anchor ring radial dilatation, fit tightly, improved the anti-pressure ability of packing element greatly with sleeve pipe.

The specific embodiment
The specific embodiment below in conjunction with accompanying drawing and preferred embodiment detailed description the utility model.As shown in the figure; A kind of packing element shoulder protector anti-channeling anchor ring; Comprise packing element 8, shoulder protector anchor ring positioning sleeve 1; Said packing element 8 is socketed on the packer central tube 7, and said shoulder protector anchor ring positioning sleeve 1 is positioned at packing element 8 tops and is fixedly mounted on the packer adapter 6, and said shoulder protector anchor ring positioning sleeve 1 and 8 of packing elements are provided with some packing element shoulder protector anti-channeling anchor rings 4 and conical surface packing element spacer ring 5; Packing element shoulder protector anti-channeling anchor ring is the polylith assembly, is arranged on the ring week of packer central tube ring week.The inward flange 1-2 that said shoulder protector anchor ring positioning sleeve 1 end opening is provided with; The screw thread 1-1 that is provided with suitable for reading; Said packing element shoulder protector anti-channeling anchor ring top outwardly-bent one-tenth groove 4-1; And form return spring steel loop fastening circular arc 4-2, and the inward flange 1-2 that forms said groove 4-1 of conical surface 4-4 and shoulder protector anchor ring positioning sleeve end opening at the back side of packing element shoulder protector anti-channeling anchor ring fastens, and said packing element shoulder protector anti-channeling anchor ring is axis swing with the inward flange; The cross section of said conical surface packing element spacer ring is trapezoidal, and the inclined-plane of the trapezoidal hypotenuse of this conical surface packing element spacer ring and packing element shoulder protector anti-channeling anchor ring bottom is slidingly matched.Be used to accept motive force, and make compressing packing element shoulder protector anti-channeling anchor ring radial dilatation and sleeve pipe interlock, play the double action of anchoring string and packing element shoulder protector from packing element.
In order to increase the frictional force on packing element shoulder protector anti-channeling anchor ring surface, the external surface of said packing element shoulder protector anti-channeling anchor ring is that zigzag forms dentation anchor tooth 4-3.Stud with bowl-shape return spring steel loop 3 between said packing element shoulder protector anti-channeling anchor ring and the shoulder protector anchor ring positioning sleeve, be used for packing element shoulder protector anti-channeling anchor ring resetting after motive force is removed.The top of said packing element shoulder protector anti-channeling anchor ring is provided with return glue ring 2, is used for resetting and limit it and under free state, freely swinging of auxiliary packing element shoulder protector anti-channeling anchor ring.
Operating principle: the up compression packing element 8 of power part 9 pressure-bearings on the packer; Conical surface packing element spacer ring is up along packer central tube 7 under the compressing of packing element; Force packing element shoulder protector anti-channeling anchor ring 4 radial dilatation, fit tightly, improved the anti-pressure ability of packing element greatly with sleeve pipe 10; Packing element top is stressed evenly on the other hand, has avoided the packing element catching phenomenon.The motive force of the power part on packer disappears or packer is separated and is honored as a queen, and resilience through bowl-shape return spring steel loop 3 and extruded return glue ring 2 discharge and order about packing element shoulder protector anti-channeling anchor ring and reset.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
