Abstract
The utility model relates to an oil gas field oil -water well operation downhole tool field, concretely relates to easily bore bridging plug slips who uses at oil, natural gas completion practice in -process. An easily bore bridging plug slips, inlay a plurality of slips teeth on the slips, the slips surface is encircled in proper order and is established bilayer structure, and inferior skin is glass short -staple structure, and the skin is the one -way cloth structure of glass fibre, and slips tooth outer surface also encircles and establishes the one -way cloth structure of glass fibre. The utility model discloses easily bore bridging plug slips lays the one -way cloth structure of one deck glass fiber at slips tooth skin, alleviate the slips tooth because of stress concentration to the slips structural damage, improve the setting force of slips, the slips surface is encircled in proper order and is established bilayer structure, and inferior skin is glass short -staple structure, the outer one -way cloth structure of glass fibre that is, and easily boring nature is better to make combined material.
Description
Technical field
This utility model relates to oil gas field oil-water well operation downhole tool field, is specifically related to a kind of easily brill bridging plug slips used during oil, natural gas completion practice.
Background technology
Traditional wellfracturing bridging plug is mainly manufactured by metal material, serves good staged fracturing effect, but metal material is difficult in drillng operation drill through after fractured horizontal well, improves drilling well difficulty, reduces efficiency of construction.A kind of easily being bored bridging plug by what composite manufactured to this end, develop in recent years, this material is mainly made up of galss fiber reinforced resin matrix, and drillability is good, substantially increases drilling efficiency, therefore, becomes the preferred bridging plug kind in wellfracturing engineering.Such as in July, 2015 National Boss Hog
The composite hole plug that Energy Services LLC is wound around at glass fiber winding a kind of disclosed in United States Patent (USP) US9,074,439 or glass cloth or molds；In July, 2015 Halliburton
Energy Services company discloses the restriction ring on a kind of downhole tool prepared by engineering plastics in United States Patent (USP) US9,080,417.
Easily bore in bridging plug at composite, using the teaching of the invention it is possible to provide maximum pressure up to 57MPa, meet general wellfracturing well envelope, but the requirement of engineering that frac pressure is bigger can't be adapted to.Therefore, in October, 2014 DIAMONDBACK
Industries company, in United States Patent (USP) US8, discloses in 887,818B1 and a kind of uses glass fibre or the composite of carbon fiber winding molding or particles filled plastics hole plug and bridging plug, but slips tooth and slips are still made for metal.
It is 90 ° of slips of making of 20mm thick fiberglass reinforced epoxy sheet material laid by 100 layers of one-way glass fiber cloth prepreg with interlayer fiber angle that the Chinese patent (application number 201320623556.7) of Sinopec Group 2013.10.10 application discloses a kind of, and it is high, corrosion-resistant and be prone to advantages such as boring except and mill out that the packer slip produced has intensity relative to metal slips.But the setting force of this slips does not disclose.
Summary of the invention
This utility model aims to the problems referred to above, proposes a kind of slips tooth stress concentration effect to slips that reduces, thus improves the setting force of slips and the easily brill bridging plug slips of easy boring property.
The technical solution of the utility model is:
A kind of easily brill bridging plug slips, described slips is inlayed some slips teeth, and described slips surface ring successively sets double-decker, and secondary outer layer is staple glass fibre structure, and outer layer is glass fibre unidirectional cloth structure, and slips tooth superficies also ring sets glass fibre unidirectional cloth structure.
Described slips material is glass fiber reinforced epoxy resin or phenolic resin, and slips teeth material is metal.
Described time glass outer chopped fiber structural thickness is 10-13mm, fibre length 5-10
mm；Glass outer one-way fiber fabric structural thickness is 1.0-2.5mm.
Described slips tooth is 4-6, and the square shape that slips tooth is length of side 8mm；Slips ring gear is around the glass fibre unidirectional cloth structure that a layer thickness is 0.3-0.9mm.
Of the present utility model have the technical effect that
This utility model easily bores bridging plug slips and lays layer of glass unidirectional cloth structure at slips tooth outer layer, alleviates slips tooth stress and concentrates slips structural damage, improves the setting force of slips；Slips surface ring successively sets double-decker, and secondary outer layer is staple glass fibre structure, and outer layer is glass fibre unidirectional cloth structure, makes composite easily boring property more preferable.
Accompanying drawing explanation
