Description
Technical field
The present invention relates to a kind of eccentric abrasion prevention coiled rod and its preparation facilities, in particular to a kind of MULTILAYER COMPOSITE eccentric abrasion prevention
The preparation facilities of coiled rod.
Background technique
Since the Oil Reservoir Types of exploitation become increasingly complex, while the continuous deterioration of well depth being continuously increased with well mine environment,
Corrosion and eccentric wear problem become oil extraction in oil field technique urgent problem to be solved.Because having the corrosion resistant feature of high-strength light, institute
Start to replace traditional metal sucker rod gradually with composite material sucker rod.Currently used composite material sucker rod mainly wraps
Include glass fiber reinforced plastic oil pumping rod and carbon fibre reinforced composite coiled rod two major classes.Glass fiber reinforced plastic oil pumping rod is increased using glass fibre
Prepared by the pultrude process one-pass molding of heat-flash thermosetting resin, have been widely used, but as the reliability requirement that the modern times recover the oil is continuous
Improve, glass fiber reinforced plastic oil pumping rod has been unable to meet requirement, be primarily present following problems, 1, the resistance to eccentric wear of sucker rod it is bad；2, tired
Intensity is inadequate；3, respectively there is a metal joint at the equal fixed length of glass fiber reinforced plastic oil pumping rod, both ends, are answered between root and root using metal sucker rod
Metal box cupling is attached, and since structure is complicated, difficulty of processing is big, expensive.Each glass fiber reinforced plastic oil pumping rod is with two
A metal joint, the cost of the two metal joints are much higher than the cost of a glass reinforced plastic body of rod；In addition it pumps with conventional metals
Bar compares, and in addition to shank portion has replaced material, the other parts of entire rod string have no change, conventional metals sucker rod
Column joint is more, and breaking, de- probability is high, and piston effect is obvious, and the box cupling problem serious with oil pipe eccentric wear is not resolved.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 reduces the covering material used, reduces continuous cladding cost and process complexity, but
Its injection molding abrasionproof block size is smaller, and relatively independent is distributed in the body of rod, and anti-abrading block and the body of rod are detached from frequent occurrence, " sugared calabash occurs
Reed " phenomenon.In addition, its body of rod fixed length, it not can 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 lesser body of rod of size anti-bias abrading block be not can 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 to solve.It is compound that CN101396874 discloses a kind of eccentric abrasion prevention
The preparation method and device of material sucker rod, preparation method are to utilize leaching on molded composite material oil pumping club shaft
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 antiwear characteristic, but with after thermosetting resin formation composite material, there are many wear resistance decrease, and the service life can not
How much is extension.Other than it has the eccentric abrasion prevention layer of spiral tendon shape, disadvantage 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 transversely arranged aramid fiber or ultra high molecular weight polyethylene fiber beam and longitudinal glass fibre
It is compound, enhancing sucker rod transverse direction interlaminar shear strength is mainly solved, to avoid sucker rod that longitudinal splitting occurs in oil well
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 process), clad are fabric enhancing
Thermosetting resin not only increases material cost, but also the resistance to eccentric wear of fabric clad is not ideal enough.In addition, due to
The carbon fibre reinforced composite coiled rod cross sectional shape is rectangle or ellipse, and its thickness only has 3~5mm, is answering
When removing well operations with special equipment, the material of retained part can not almost be selected, and can only be clamped using two-piece type, left and right
Direction can not limit, it is easy to which there is a phenomenon where the bodies of rod to deflect away from retained part.Therefore its dedicated operating equipment retained part of going into the well
Structure and developing material difficulty are larger, become 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, coating thermoplastic wearing layer method, that there are radial compressive properties is poor for structure, and thermoplastic wear resistant layer is hard
The defects of degree is not high, and wear-resisting property is poor, is unable to satisfy long-time service and job requirements.
Chinese patent literature number is 103075112A, and patent name is that " a kind of fibre reinforced composites eccentric abrasion prevention is continuous
Sucker rod and its preparation facilities and method ", for the patent of invention that our company declared on November 30th, 2012, technical side
Case is that be covered with one layer of thermoplastic at one section or several sections of the outer surface of the fiber-reinforced resin matrix composite body of rod wear-resisting
Layer, the fiber that the body of rod uses is made of one kind of glass fibre, carbon fiber or basalt fibre, resin matrix be epoxy resin,
One kind of polyurethane resin or vinyl ester resin.By being provided with a plastic extrusion between traction device and winding device
Machine and cooling device adhere to one layer of thermoplastic on one section or several sections of surface of the molding oil pumping body of rod using plastic extruder
Wearing layer forms fibre reinforced composites eccentric abrasion prevention coiled rod then through apparatus for supercooling cooling treatment.Beneficial effect
It is: imparts the excellent corrosion-resistant and resistance to eccentric wear performance of sucker rod, and greatly reduce connector quantity, de- probability is resolved in reduction
And piston effect, in addition, its high production efficiency, easy to operate.Itself the problem is that, since the thermoplastic of use is wear-resisting
Layer, bending property and radially, axially compressive property is slightly more inferior；In addition, temperature tolerance, wear resistence are also than thermosetting property wearing layer
Performance is weaker.
Summary of the invention
The purpose of the present invention is to drawbacks described above of the existing technology, and it is continuous to provide a kind of MULTILAYER COMPOSITE eccentric abrasion prevention
The preparation facilities of sucker rod is to be covered with one layer in one section or several sections of the outer surface of the fiber-reinforced resin matrix composite body of rod
