Abstract

The invention discloses a sucker rod with a composite spiral abrasion-resistant layer, a manufacturing device and a manufacturing method. The abrasion-resistant layer made of fiber reinforced thermoplastic resin-matrix composite materials covers the surface of the sucker rod, reinforced fibers of the abrasion-resistant layer are aramid fibers or ultrahigh molecular weight polyethylene fibers, resin matrixes of the abrasion-resistant layer are made of one of polyethylene, polyamide, polyphenyl ether, polysulfone, polyphenylene sulfide, polytetrafluoroethylene, polyoxymethylene or polyether ether ketone; the reinforced fibers can be wound on the surface of the sucker rod in such a manner that narrow bands made of two-dimensional fabrics are wound on the surface of the sucker rod. The sucker rod, the manufacturing device and the manufacturing method have the advantages that the sucker rod with the structure is excellent in deflection abrasion resistance, the abrasion-resistant layer on the surface of the sucker rod has certain toughness and strength, the problem of crack in sucker rod winding procedures due to poor mechanical properties of pure thermoplastic resin can be solved, micro-pore meshed structures are subjected to strong interface bonding owing to the self-protection layer made of the thermoplastic composite materials and a sucker rod body, and the self-protection abrasion-resistant layer can be prevented from slipping and layering from the surface of the sucker rod.

Description

technical field [0001] The invention relates to oil production equipment and manufacturing technology in the petroleum industry, in particular to a sucker rod with a composite spiral wear-resistant layer, a preparation device and a preparation method. Background technique [0002] Due to the complex and diverse types of oil wells in China, the depth of oil wells and the downhole environment are also deteriorating with the increase of production scale. Therefore, although traditional steel sucker rods have been gradually replaced by composite material sucker rods, this high-performance material The high-quality sucker rod inevitably faces the problems of corrosion and eccentric wear. At present, the composite sucker rods used in China mainly include two types: glass fiber reinforced resin-based composite sucker rods and carbon fiber reinforced composite sucker rods. At present, FRP sucker rods have low fatigue strength and are easy to break, so they cannot adapt to the highl...
