Abstract
The present invention relates to a tension rod made of composite, its skelton material possesses carbon fibre bundle woven fabric, carbon fibre bundle and aromid fiber bundle mixed woven fabric or steel wire bundle woven fabric, after it is tensed, it is bound by using epoxy resin adhesive fixing agent, then extruded and pulled in mould, and heated and formed so as to obtain the invented tension rod with high tensile strength, low cost, anticorrosion property, long service life, high temp. resistance and extensive application range. Said invention tension rod can be used as pumping rod in oil well, its rod length can be up to above 1500m-2500m, also can be extensively used in the field of traction at sea, etc.
Description
The present invention relates to sucker rod and stayed mast technical field.
The most of oil field of China all is to adopt solid sucker rod at present, and its plastid is heavy, and pump efficiency is low, high power consumption, and the cost for oil production height, joint is many, and installation is wasted time and energy.World's sucker rod technology trends has hollow stem, spraying stainless steel, multiple strengthening sucker rod, the continuous bar of steel band and the wire rope bar of new construction, in use there are deficiencies such as body weight, intensity is lower, the life-span is short, the U.S., Canada have adopted flat-shaped carbon fibre pumping rod, tensile strength is higher, but the cost cost is too high, be difficult to large tracts of land employing and popularization, and heatproof lower (78 ℃ can not be used as the coiled rod of well depth about 2500mm).
Task of the present invention provides a kind of composite mateiral tension rod, its tensile strength height, and anti-corrosion, the life-span is long, and the cost cost is low, has wide range of applications.
The present invention is achieved in that a kind of composite mateiral tension rod, its material has following structure: framework material is that the synthetic resin-bound fixative is passed through in carbon fiber bundle mesh grid, carbon fiber bundle and aramid fiber bundle mixed weaving net or braided steel wire net tension back, makes by pultrusion in the mould or crowded La Jiawen moulding again.
For making it to have good comprehensive mechanical performance, it is 1 that best carbon fiber bundle is counted ratio with the aramid fiber bundle: 0.8-1.2.
Synthetic resin is best for being the heatproof synthetic resin of base-material with epoxy resin or vinyl acids resin, heatproof＞120 ℃.
Mesh grid can be monolithic or splintery, or is the rectangular pocket-like that is crushed, and stayed mast is bandlet shape.
Can have the carbon fiber bundle framework material in the braiding mesh bag that is crushed, or carbon fiber bundle and aramid fiber bundle mixed matrix material, the stayed mast cross section is flat or flat ellipse.
Above-mentioned carbon fiber bundle number, with aramid fiber bundle number be 1 than the best: 0.8-1.2.
Also can have aramid fiber Shugu frame material or aramid fiber Shugu frame material and glass fiber bundle mixed matrix material in the braiding mesh bag that is crushed, or be impregnated with the steel-wire carcass material, the stayed mast cross section is flat or flat ellipse.
The aramid fiber bundle is 10-30: 5-20 with the bundle number of glass fiber bundle than the best.
Mesh grid also can be rectangular pocket-like, and cross section is rounded or square, and stayed mast is cylindric or the square tube shape.
Preferably be provided with the cannon born frame of materials such as stainless steel, aluminium alloys in the braiding mesh bag in the above-mentioned cylindric stayed mast, effect also can.
The present invention has utilized tensile strength of carbon fibers advantage high and wear-resisting, heatproof, has avoided the shortcoming that carbon fiber is crisp, the mill amount is low simultaneously again as far as possible.The mesh skeleton structure has not only guaranteed to have in the longitudinal direction high tensile strength, has guaranteed that again it laterally has higher strength character, is difficult for laterally fractureing.The present invention has also utilized aramid fiber tension strength height, and is flexible good, characteristics such as mill amount height, and glass fiber cost cost is low, also characteristics preferably of heatproof, tensile strength.Synthetic resin can be selected intensity height, great thermotolerance for use by variety classes, satisfying actual operating conditions.Because the present invention can be hollow section, so can improve the combination property of stayed mast.The key property that the present invention has is: the tensile strength height, and corrosion resistance is good, and the life-span is long, and the cost cost is low, has wide range of applications.Different materials, different structure can be satisfied with the functional performance of different operating occasion.Applicable to the deep-well more than the deep-well sucker rod 1500m-2500m, heatproof＞120 ℃ or＞200 ℃, can replace existing Metallic rod, wire rope etc., performance and price is superior.Also can be widely used in marine traction waits other to need the occasion of stayed mast.Can be single continuous stock, also can be made into the assembly type stock, very economical practicality.Steel wire mesh bag type stayed mast is particularly suitable for well rod.
Describe in further detail below in conjunction with embodiment, but not as to concrete qualification of the present invention.
Fig. 1 is the cross-sectional configuration schematic diagram of embodiment 1.
Fig. 2 is the cross-sectional configuration schematic diagram of embodiment 2.
Fig. 3 is the cross-sectional configuration schematic diagram of embodiment 3.
Referring to Fig. 1,1 is the woven mesh carbon fiber, and make by mould pultrusion or crowded La Jiawen moulding by heatproof synthetic resin 2 the tension back again.
Referring to Fig. 2, it is 1 that carbon fiber is counted ratio with the aramid fiber bundle: 0.8-1.2, and be and mix netted pocket-type 3, (or only using the gauze wire cloth woven bag) flattens the back tension by the moulding of heating of resin 2 and mould.
Referring to Fig. 3, pocket-type mesh grid 4 usefulness carbon fiber bundles or carbon fiber bundle and aramid fiber bundle mixed weaving form, and carbon fiber bundle is counted ratio with the aramid fiber bundle and is: 1: 0.8-1.2, the centre is an aramid fiber bundle 5, or the aramid fiber bundle is 10-30: 5-20 with glass fiber bundle number ratio.As each 18 bundle of mesh grid carbon fiber and aramid fiber, in carbon fiber and each 32 bundle (1000 of every bundle standards) of aramid fiber are arranged.
Referring to Fig. 4, make square.
Referring to Fig. 5, the mesh grid of bag shape is a circle 6, and heating with the mould pultrusion forms.
Referring to Fig. 6, the mesh grid of bag shape is square 7.The all same Fig. 1 of other labels.
Above-mentioned synthetic resin available epoxy or vinyl acids resin are the heatproof synthetic resin of base-material, and heatproof reaches more than 120 ℃, or heatproof satisfies condition of work and gets final product.
Example: Fig. 3 structural poles, material are celion (or asphalt-based carbon fiber etc.), and interior is aramid fiber and glass fiber, synthetic resin composite material.Its performance parameter that records is as follows:
1, specification: (1-10m) * 32.5 * 2.6mm
2, line density: 0.1kg/m, modulus of elasticity 1.5 * 10
5MPa destroys pulling force 100-120KN, destroys section elongation rate 1% ± 0.1%, impact strength 2.6KJm
