Description
Technical field
The present invention relates to a kind of sucker rod to recover the oil for industry, in particular to a kind of fibre reinforced composites are continuously taken out
Beam hanger and its preparation facilities and method belong to petroleum industry technical field of oil extraction equipment.
Background technique
In petroleum industry production, etching problem is oil extraction in oil field technique urgent problem to be solved.Sucker rod is connection oil pumping
The critical component of machine and oil well pump, stress is complicated, and working environment is severe, itself is easily seriously affected because being corroded and uses the longevity
Life causes great cost to waste to oil field production.Due to having lightweight, high-strength, corrosion resistant feature, composite material sucker rod
Started gradually to replace traditional metal sucker rod, currently used composite material sucker rod mainly 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 prepared using the pultrude process one-pass molding of glass-fiber reinforced thermo-setting resin, is answered extensively
With, but as the reliability requirement that the modern times recover the oil is continuously improved, glass fiber reinforced plastic oil pumping rod has been unable to meet requirement, is primarily present following
Problem: 1) the resistance to eccentric wear of sucker rod is bad；2) axial tension modulus is low, and deformation is big, and oil well pump effective travel is caused to be greatly decreased,
Oil recovery efficiency reduces obvious；3) respectively there is a metal joint at the equal fixed length of glass fiber reinforced plastic oil pumping rod, both ends, and metal is used between root and root
The metal box cupling of pumping rod application is attached, and since structure is complicated, causes difficulty of processing big, while each glass fibre reinforced plastic pumping
Two metal joints of bar, it is expensive；In addition compared with conventional metals sucker rod, glass fiber reinforced plastic oil pumping rod in addition to shank portion more
Material is changed, the other parts of entire rod string have no change, and column joint present in conventional metals sucker rod is more, and breaking, it is several to take off
The problems such as rate is high, and piston effect is obvious is not resolved.
The research of carbon fibre reinforced composite coiled rod also has very much, as Chinese patent CN1461870 is disclosed
A kind of carbon fibre reinforced composite coiled rod and preparation method, use carbon fiber for reinforcing material, and by transversely arranged
Aramid fiber or ultra high molecular weight polyethylene fiber beam and longitudinal glass fibre composition integral coating it is compound, it is intended to increase sucker rod
Lateral interlaminar shear strength, while also improving the resistance to eccentric wear and intensity of the body of rod.But it is found in practical application, which uses
Pultrusion, cladding an integral processing method (including put silk-resin pickup glue-clad cladding-preforming-solidification-coiling work
Sequence), clad is that fabric enhances thermosetting resin, not only increases material cost, but also fabric clad is resistance to
Eccentric wear is not ideal enough；Clad is fabric, seems complete package the body of rod one week, but always exists fabric seam problem,
The problems such as that there are lap widths is uneven for seam crossing, squeezes internal unidirectional fibre, and transverse strength is low；In addition, due to the carbon fiber
Enhancing composite continuous sucker rod cross sectional shape is rectangle or ellipse, and its thickness only has 3~5mm, sets in application specific
For when removing well operations, the material of retained part can not almost be selected, and can only be clamped using two-piece type, and left and right directions 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 structure and material of going into the well
Expect that development difficulty is larger, becomes the technical bottleneck in application, limit the product large-scale promotion application.
In addition a kind of fibre reinforced composites eccentric abrasion prevention is disclosed there are also Chinese invention patent CN201210501186.X
Coiled rod and its preparation facilities and method are used using unidirectional reinforcing fiber pultrusion, the method for coating thermoplastic wearing layer
Fiber be only glass fibre, carbon fiber or basalt fibre one kind, not yet explicitly body of rod cross sectional shape and size, because only adopting
With single longitudinal fiber, transverse strength is low, there are radial compression, bending property is poor the problems such as；Using single glass fiber or
Basalt fibre, axial tension modulus is low, and deformation is big, and similar glass fiber reinforced plastic oil pumping rod will lead to oil well pump effective travel substantially
It reduces, oil recovery efficiency reduces obvious；Using single carbon fiber, rod body material cost is very high, increases axial tension modulus
Meanwhile bending modulus also becomes larger, and causes bending difficult, is not able to satisfy road transport requirement and job requirements, limits its popularization
Using.
