A kind of preparation facilities of MULTILAYER COMPOSITE eccentric abrasion prevention coiled rod
Technical field
The present invention relates to a kind of eccentric abrasion prevention coiled rod and its preparation facilities, more particularly to a kind of MULTILAYER COMPOSITE eccentric abrasion prevention
The preparation facilities of coiled rod.
Background technology
Because the Oil Reservoir Types developed become increasingly complex, while the continuous deterioration being continuously increased with well ore deposit environment of well depth,
Corrosion and eccentric wear problem turn into oil extraction in oil field technique problem demanding prompt solution.Because possessing the corrosion resistant feature of high-strength light, institute
Have started to progressively replace traditional metal sucker rod with composite sucker rod.The composite sucker rod for using at present is mainly wrapped
Include glass fiber reinforced plastic oil pumping rod and the major class of carbon fibre reinforced composite coiled rod two.Glass fiber reinforced plastic oil pumping rod is increased using glass fibre
Prepared by the pultrude process one-shot forming of heat-flash thermosetting resin, have been widely used, but as the modern reliability requirement for recovering the oil is continuous
Improve, glass fiber reinforced plastic oil pumping rod can not meet requirement, be primarily present problems with, 1, the resistance to eccentric wear of sucker rod it is bad;2nd, fatigue
Insufficient strength;3rd, respectively there is a metal joint at the equal fixed length of glass fiber reinforced plastic oil pumping rod, two ends, should using metal sucker rod between root and root
Metal box cupling is attached, and due to complex structure, difficulty of processing is big, expensive.Each glass fiber reinforced plastic oil pumping rod uses two
Individual metal joint, the cost of the two metal joints is far above a cost for the fiberglass body of rod;Pumped with conventional metals in addition
Bar compares, and except shank portion has changed material, the other parts of whole rod string have no change, conventional metals sucker rod
Column joint is more, and the de- probability that breaks is high, and substantially, the box cupling problem serious with oil pipe eccentric wear is not resolved piston effect.It is Chinese special
Sharp CN1417449 discloses a kind of preparation method of Anti-wear oil pumping rod, and the method is secondary in molded oil pumping bar body
The anti-abrading block of the materials such as injection moulding nylon, the covering material that reduction is used reduces continuous cladding cost and process complexity, but
Its injection abrasionproof block size is smaller, and relatively independent is distributed in the body of rod, anti-abrading block often occurs and departs from the body of rod, " sugared calabash occurs
Reed " phenomenon.In addition, its body of rod fixed length, it is impossible to which it is more to solve conventional metals rod connector, break-off accident rate is big, and piston effect is big
Etc. defect;And installed additional on the less body of rod of size anti-bias abrading block be can not solve it is inclined between metal joint and box cupling and oil pipe
Mill problem, and this is only the emphasis that sucker rod, pipe eccentric wear need to solve.CN101396874 discloses a kind of eccentric abrasion prevention and is combined
The preparation method and device of material sucker rod, its preparation method are on molded composite oil pumping club shaft, using leaching
Stain crosses the eccentric abrasion prevention layer of the abrasion resistant fibrous continuous-winding forming spiral tendon shape such as the aramid fiber of resin adhesive liquid, High molecular weight polyethylene, with
Reach eccentric abrasion prevention effect.The eccentric abrasion prevention layer of its spiral tendon shape, due to being with abrasion resistant fibrous enhancing thermosetting resin, thus while fine
Dimension is that, with antiwear characteristic, but after forming composite with thermosetting resin, its wear resistance decrease is a lot, and the life-span can not
How much is extension.In addition to its eccentric abrasion prevention for possessing spiral tendon shape layer, its shortcoming is as common glass fiber reinforced plastic oil pumping rod.China
Patent CN1461870 discloses a kind of carbon fibre reinforced composite coiled rod and preparation method, uses carbon fiber to increase
Strong material, and integral coating is constituted by transversely arranged aramid fiber or superhigh molecular weight polyethylene fibers beam and longitudinal glass fibre
It is compound, enhancing sucker rod transverse direction interlaminar shear strength is mainly solved, there is longitudinal splitting in oil well so as to avoid sucker rod
Problem, while also improving the resistance to eccentric wear and intensity of the body of rod.But the sucker rod is using pultrusion, an overall processing of cladding
Method(Including putting silk-resin pickup glue-clad cladding-preforming-solidification-coiling operation), clad is fabric enhancing
Thermosetting resin, not only increases material cost, and the resistance to eccentric wear of fabric clad is not ideal enough.Further, since
The carbon fibre reinforced composite coiled rod cross sectional shape is rectangle or ellipse, and its thickness only has 3~5mm, is being answered
When removing well operations with special equipment, the material of retained part cannot almost be selected, and can only be clamped using two-piece type, left and right
Direction cannot be spacing, it is easy to which the phenomenon that the body of rod deflects away from retained part occurs.Therefore its special implement retained part of going into the well
Structure and developing material difficulty are larger, as the technical bottleneck in carbon fibre reinforced composite coiled rod application, limitation
The product large-scale promotion application.Patent of invention CN200910272324.X discloses a kind of coiled rod, using unidirectional
Reinforcing fiber pultrusion, the method for coating thermoplastic wearing layer, it is poor to there is radial compressive property in its structure, and thermoplastic wear resistant layer is hard
Degree is not high, the defect such as anti-wear performance is poor, it is impossible to meet long-term use and job requirements.
