Abstract
The utility model relates to a kind of inflatable anchoring packer packing element, arranges inner liner metal part at the two ends of sebific duct, and the outer end excircle of inner liner metal part is provided with external screw thread; Excircle in the middle part of sebific duct is provided with annular anchors, and anchors is provided with anchor tooth; Inner liner metal part inner end and except the anchors of anchor tooth part by sulfuration process with sebific duct in conjunction with as a whole.This inflatable anchoring packer packing element structure is simple, and set, deblocking is rapid, the compression set of packing element is little, meanwhile, packing element itself has grappling function, grappling when packing element sets, namely the grappling of packing element deblocking is removed, stopped because anchor tooth does not reclaim the card well accident caused, and anchorage force is higher than the anchorage force of any one hydraulic anchor in the market, higher operating pressure and operating temperature can be born simultaneously.
Description
Technical field
The utility model relates to a kind of inflatable anchoring packer packing element, belongs to a kind of oil field downhole tool.
Background technology
At present, oil field, when oil recovery, water filling, fracture acidizing operation, generally adopts packer to realize setting.Because inflatable packer relies on packing element to expand outwardly packing oil sets annular space, therefore require that packing element has good bearing capacity.And need with this instrument of hydraulic anchor with the use of, just can reach the Expected Results of instrument.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of inflatable anchoring packer packing element, this inflatable anchoring packer packing element structure is simple, and set, deblocking is rapid, the compression set of packing element is little, simultaneously, packing element itself has grappling function, grappling when packing element sets, namely the grappling of packing element deblocking is removed, stop because anchor tooth does not reclaim the card well accident caused, and anchorage force is higher than the anchorage force of any one hydraulic anchor in the market, higher operating pressure and operating temperature can be born simultaneously.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of inflatable anchoring packer packing element, arranges inner liner metal part at the two ends of sebific duct, and the outer end excircle of inner liner metal part is provided with external screw thread; Excircle in the middle part of sebific duct is provided with annular anchors, and anchors is provided with anchor tooth; Inner liner metal part inner end and except the anchors of anchor tooth part by sulfuration process with sebific duct in conjunction with as a whole.
Described anchors is several outer anchors of being interspersed of circumference and interior anchors, and the excircle after its China and foreign countries' anchors merges is anchor tooth, and the external surface of each interior anchors is ARROW structure, and the external surface of interior anchors is filled by outer anchors; Be respectively equipped with positioning tie bar at the two ends of each outer anchors and interior anchors, positioning tie bar and sebific duct by sulfuration process in conjunction with as a whole.
Described is surrounded with fluid sealant on positioning tie bar, and the diameter of fluid sealant is less than anchor tooth diameter 0.1-0.5mm
Described inner liner metal part is provided with annular table, is provided with ferrule in annular table the inner, and ferrule sulfuration, in sebific duct, is provided with gauze wire cloth in sebific duct, and the two ends of gauze wire cloth are pressed in the annular table of inner liner metal part by ferrule.
High molecule spinning thing skeleton is provided with in described sebific duct.
This inflatable anchoring packer packing element, on the basis of original sealed rubber pipe structure, adds the structure of anchor tooth, thus adds the anchorage force of packing element entirety.
The structure adopting outer anchors and interior anchors to coordinate, make Inflatable type packer rubber sleeve self have grappling function, and anchoring effect is good, guarantees packing element stability in the course of the work; Meanwhile, whole sebific duct capsula interna part carries out work completely in steel part, makes rubber at high temperature bear higher mechanical strength, guarantees packing element stability in the course of the work.
In packing element, arrange steel mesh structure, the outside anchors that adopts protects packing element capsula interna, enables overall packing element bear higher pressure; The bulk strength that high molecule spinning thing skeleton ensure that sebific duct is provided with in sebific duct.

Detailed description of the invention
As shown in Figures 1 to 4, a kind of inflatable anchoring packer packing element, arranges inner liner metal part 3 at the two ends of sebific duct 1, and the outer end excircle of inner liner metal part 3 is provided with external screw thread 4, and external screw thread is used for fixing with well body; Excircle in the middle part of sebific duct 1 is provided with annular anchors, and anchors is provided with anchor tooth 7; Inner liner metal part 3 inner end and except the anchors of anchor tooth 7 part by sulfuration process with sebific duct 1 in conjunction with as a whole.The anchor tooth that sebific duct is arranged can be out of shape in the course of the work, and tightly fits with the borehole wall and play the effect of grappling.
Described anchors is several outer anchors 10 and interior anchors 11 that circumference is interspersed, and the excircle after its China and foreign countries' anchors 10 merges is anchor tooth 7, and the external surface of each interior anchors 11 is ARROW structure, and the external surface of interior anchors 11 is filled by outer anchors 10; Be respectively equipped with positioning tie bar 8 at the two ends of each outer anchors 10 and interior anchors 11, positioning tie bar 8 and sebific duct 1 by sulfuration process in conjunction with as a whole.Ensure that in the process that anchors expands at packing element that there is good telescopicing performance by the syndeton of outer anchors and interior anchors.
Described is surrounded with fluid sealant 9 on positioning tie bar 8, the diameter of fluid sealant 9 is less than anchor tooth 7 diameter 0.1-1mm, while effective packing stratum, anchor tooth two ends after sealing expansion, prevent fracturing propping agents from entering the inner and shaft bottom material of the anchor tooth after expansion to the corrosion of anchor tooth, guarantee the stability of grappling and remove the reliability of grappling.
Described inner liner metal part 3 is provided with annular table, is provided with ferrule 6 in annular table the inner, and ferrule 6 sulfuration, in sebific duct 1, is provided with gauze wire cloth 5 in sebific duct 1, and the two ends of gauze wire cloth 5 are pressed in the annular table of inner liner metal part 3 by ferrule 6.High molecule spinning thing skeleton 2 is provided with in described sebific duct.Arrange gauze wire cloth and high molecule spinning thing cage construction in sebific duct, what ensure that sebific duct can bear higher pressure, arranges ferrule structure at gauze wire cloth two ends, and during use, entirety is more firm, sets, deblocking better effects if.
During work, in sebific duct 1, be filled with highly pressurised liquid, under the effect of highly pressurised liquid, sebific duct 1 expands outwardly, and in promoting, anchors and outer anchors expand outwardly simultaneously simultaneously, as shown in Figure 5, reach the object on anchoring string and packing stratum.
