Description
Technical field
The present invention relates to a kind of coiled rod, more particularly to a kind of preparation method of coiled rod.
Background technology
Because the Oil Reservoir Types of exploitation 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 urgent problem to be solved.Because possess the corrosion resistant feature of high-strength light, institute
Have started to progressively substitute traditional metal sucker rod with composite sucker rod.The composite sucker rod used at present mainly wraps
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 the reliability requirement to be recovered the oil with the modern times is continuous
Improve, glass fiber reinforced plastic oil pumping rod can not meet to require, be primarily present problems with, 1, the resistance to eccentric wear of sucker rod it is bad；2nd, it is tired
Insufficient strength；3rd, respectively there is a metal joint at the equal fixed length of glass fiber reinforced plastic oil pumping rod, both ends, should using metal sucker rod between root and root
Metal box cupling is attached, and due to complicated, difficulty of processing is big, expensive.Each glass fiber reinforced plastic oil pumping rod is with two
Individual metal joint, the cost of the two metal joints are far above the cost of a fiberglass body of rod；Pumped in addition with conventional metals
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 piston effect is obvious, is not resolved the problem of box cupling and serious oil pipe eccentric wear.It is Chinese special
Sharp CN1417449 discloses a kind of preparation method of Anti-wear oil pumping rod, and this method is secondary in molded oil pumping bar body
The anti-abrading block of the materials such as injection molding nylon, the covering material used is reduced, reduce continuous cladding cost and process complexity, but
Its injection abrasionproof block size is smaller, and relatively independent is distributed in the body of rod, and 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 solve that conventional metals rod connector is more, and break-off accident rate is big, and piston effect is big
The defects of；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 the emphasis that this is only sucker rod, pipe eccentric wear needs solve.It is compound that CN101396874 discloses a kind of eccentric abrasion prevention
The preparation method and device of material sucker rod, its preparation method are on molded composite oil pumping club shaft, utilize 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 has an 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 it possesses the eccentric abrasion prevention layer of spiral tendon shape, 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 formed by the glass fibre of transversely arranged aramid fiber or superhigh molecular weight polyethylene fibers beam and longitudinal direction
It is compound, mainly solve enhancing sucker rod transverse direction interlaminar shear strength, so as to avoid sucker rod that longitudinal splitting occurs in oil well
Problem, while also improve 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 process）, clad is fabric enhancing
Thermosetting resin, material cost is not only increased, 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 can not almost select, and two-piece type can only be used to clamp, left and right
Direction can not be spacing, it is easy to 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, turn into the technical bottleneck in the application of carbon fibre reinforced composite coiled rod, 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, its structure have that radial compressive property is poor, and thermoplastic wear resistant layer is hard
The defects of degree is not high, and anti-wear performance is poor, long-term use of and job requirements can not be met.
The content of the invention
The purpose of the present invention is aiming at drawbacks described above existing for prior art, there is provided a kind of preparation side of coiled rod
Method, to solve the problems, such as the corrosion in oil extraction in oil field production and eccentric wear, solve influence of the high temperature well-flushing to the body of rod, solve deep-well ultra-deep
Well oil recovery problem is main purpose, prepares the oil pumping that corrosion-resistant and resistance to eccentric wear performance is good, piston effect is small, operation is easy to use
Bar.
