The sucker rod has the beneficial effects that the radial strength and the axial compressive strength are enhanced; the corrosion resistance and the eccentric wear resistance of the thermosetting wear layers are improved by 30%; the maximum temperature tolerance of the thermosetting wear layers is up to 190 DEG C; meanwhile, the bonding between an sucker rod body and each thermosetting wear layer is greater in length and quite high in strength, so that the slippage and the layering of an eccentric-wear-preventing layer from the surface of the sucker rod in the normal operation of an oil well are avoided.
Description
Technical field
The present invention relates to a kind of anti-eccentric wear coiled rod and preparation facilities thereof, particularly the anti-eccentric wear coiled rod of a kind of MULTILAYER COMPOSITE and preparation facilities and method.
Background technology
Because the Oil Reservoir Types of developing becomes increasingly complex, the continuous increase of well depth simultaneously and the continuous deterioration of well ore deposit environment, corrosion and eccentric wear problem become oil extraction in oil field technique problem demanding prompt solution.Because possess the corrosion resistant feature of high-strength light, so composite material sucker rod has started progressively to replace traditional metal sucker rod.The composite material sucker rod adopting at present mainly comprises glass fiber reinforced plastic oil pumping rod and the large class of carbon fibre reinforced composite coiled rod two.Glass fiber reinforced plastic oil pumping rod adopts the pultrude process one-shot forming preparation of glass-fiber reinforced thermo-setting resin, extensive use, but along with the reliability requirement of modern times oil recovery improves constantly, glass fiber reinforced plastic oil pumping rod can not meet the demands, mainly there is following problem, 1, the resistance to eccentric wear of sucker rod is bad; 2, fatigue strength is inadequate; 3, the equal fixed length of glass fiber reinforced plastic oil pumping rod, respectively there is a metal joint at two ends, between root and root, adopt the metal box cupling of metal pumping rod application to be connected, and due to complex structure, difficulty of processing is large, expensive.Two metal joints for each root glass fiber reinforced plastic oil pumping rod, the cost of these two metal joints is far above the cost of a glass fiber reinforced plastic body of rod; Compare with traditional metal sucker rod in addition, except shank portion has been changed material, other parts of whole rod string there is no change, traditional metal rod string joint is many, disconnected de-probability is high, and piston effect is obvious, and the serious problem of box cupling and oil pipe eccentric wear is not resolved.Chinese patent CN1417449 discloses a kind of preparation method of Anti-wear oil pumping rod, the method is the anti-abrading block of the material such as secondary injection molding nylon in type sucker rod body, reduce the clad material using, reduce continuously coated cost and process complexity, but the anti-abrading block size of its injection moulding is less,, often there is anti-abrading block and the body of rod and depart from the relatively independent body of rod that is distributed in, occurs " sugarcoated haws " phenomenon.In addition, its body of rod fixed length, can not solve the defects such as traditional metal rod connector is many, and break-off accident rate is large, and piston effect is large; And to install anti-bias abrading block on the less body of rod of size additional be to solve eccentric wear problem between metal joint and box cupling and oil pipe, and this is only the emphasis that sucker rod, pipe eccentric wear need to solve.CN101396874 discloses a kind of preparation method and device of anti-eccentric wear composite material sucker rod, its preparation method is on the in type composite material sucker rod body of rod, the anti-eccentric wear layer of the abrasion resistant fibrous continuous-winding forming spiral bar shapes such as the aramid fiber, High molecular weight polyethylene of resin adhesive liquid was flooded in utilization, to reach anti-eccentric wear effect.The anti-eccentric wear layer of its spiral bar shape, owing to being with abrasion resistant fibrous enhancing thermosetting resin, although therefore fiber has antiwear characteristic, forms after composite material with thermosetting resin, and its wear resistance decrease is a lot, and the life-span can not extend how many.Except it possesses the anti-eccentric wear layer of spiral bar shape, its shortcoming is the same with common glass fiber reinforced plastic oil pumping rod.Chinese patent CN1461870 discloses a kind of carbon fibre reinforced composite coiled rod and preparation method, employing carbon fiber is reinforcing material, and by transversely arranged aramid fiber or superhigh molecular weight polyethylene fibers bundle and longitudinally glass fiber to form integral coating compound, mainly solve and strengthen the horizontal interlaminar shear strength of sucker rod, thereby avoid sucker rod that the problem of longitudinal splitting occurs in oil well, the while has also been improved resistance to eccentric wear and the intensity of the body of rod.But this sucker rod adopt pultrusion, coated Integratively processing method (comprise put silk-resin pickup glue-clad coated-preformed-solidify-coil operation), clad is that fabric strengthens thermosetting resin, not only strengthened material cost, and the resistance to eccentric wear of fabric clad is not ideal enough.In addition, because this carbon fibre reinforced composite coiled rod cross sectional shape is rectangle or ellipse, and its thickness only has 3～5mm, when application specific equipment removes well operations, the material of retained part almost cannot be selected, and can only adopt two-piece type clamping, left and right directions cannot be spacing, is easy to occur the phenomenon that the body of rod deflects away from retained part.Therefore its special use go into the well implement retained part structure and developing material difficulty larger, become the technical bottleneck in the application of carbon fibre reinforced composite coiled rod, limited this product large-scale promotion application.Patent of invention CN200910272324.X discloses a kind of coiled rod, use the method for unidirectional fortifying fibre pultrusion, coating thermoplastic wearing layer, its structure exists radial compressive property poor, thermoplastic wear resistant layer hardness is not high, the defects such as anti-wear performance is poor, cannot meet long-term use and job requirements.
Chinese patent literature number is 103075112A, patent name is the anti-eccentric wear coiled rod of < < fibre reinforced composites and preparation facilities and method > >, a patent of invention of declaring on November 30th, 2012 for our company, its technical scheme is that a section or several sections at the external surface of the fiber reinforced resin based composite material body of rod is covered with one deck thermoplastic wearing layer, the fiber that the body of rod adopts is glass fiber, the a kind of of carbon fiber or basalt fibre makes, resin matrix is epoxy resin, polyurethane resin or vinyl ester resin a kind of.By be provided with a plastic extruder and cooling unit between draw-gear and coiler device, utilize plastic extruder at one section or surface attachment one deck thermoplastic wearing layer of several sections of the moulding oil pumping body of rod, then through apparatus for supercooling cooling processing, form the anti-eccentric wear coiled rod of fibre reinforced composites.Beneficial effect is: given the corrosion-resistant and resistance to eccentric wear performance of sucker rod excellence, reduced greatly again joint quantity, reduced and resolve de-probability and piston effect, in addition, its production efficiency is high, easy and simple to handle.The problem of its existence is, due to the thermoplastic wearing layer adopting, its bending property and radially, axial compression resistance performance is slightly more inferior; In addition, temperature tolerance, wear resistence also than the poor performance of thermosetting wearing layer some.
