Abstract

The invention discloses a continuous carbon fiber sucker rod with a wear-resistant protective layer and a preparation method thereof, comprising a sucker rod body, a glass fiber layer coated on the surface of the sucker rod body, and a glass fiber layer coated outside A wear-resistant layer, the wear-resistant layer includes a fiber reinforced fabric and a thermoplastic resin layer coated on the surface of the fiber-reinforced fabric, the thermoplastic resin layer is evenly mixed with hard wear-resistant particles, so that the surface of the wear-resistant layer is evenly distributed with the Hard wear-resistant particles. Hard wear-resistant particles are evenly distributed on the surface of the sucker rod. Through the high hardness and wear resistance of the inorganic hard particles and the spherical ball form formed with the mesh fabric structure, the wear resistance of the wear-resistant layer on the surface of the composite sucker rod is strengthened. Partial wear characteristics. At the same time, the hard wear-resistant particles also play the role of interface mechanical engagement at the part in contact with the sucker rod body interface, preventing the slipping and delamination of the wear-resistant protective layer from the sucker rod surface.

Description

technical field [0001] The invention belongs to the field of oil production equipment in the petroleum industry, and in particular relates to a continuous carbon fiber sucker rod with a wear-resistant protective layer and a preparation method thereof. The processed carbon fiber composite continuous sucker rod surface has high-hardness inorganic particles to improve the overall durability Abrasive, it can be applied to different working conditions of various oil wells, and has a long service life. Background technique [0002] With the development of the oil extraction industry and the increase in the scale of adoption, the depth of the oil well and the complexity of the downhole environment are increasing. Rods are gradually replaced by sucker rods made of composite materials. Composite materials belong to multi-phase composite materials. At present, the composite material sucker rods used in China mainly include glass fiber reinforced resin matrix composite material sucker...
