High temperature resistant carbon fiber reinforced composite material continuous sucker rod and its preparation device and method

Abstract

The invention relates to a high-temperature resistant carbon fiber reinforced composite material continuous sucker rod and a preparation device and method. The technical solution is that from the inside to the outside, the reinforced fiber carbon fiber (A) along the axial direction of the rod body, the fiber-wound reinforcement layer aramid 1414 fiber (B); the reinforced fiber high-strength glass fiber (C) along the axial direction of the rod body, fiber braiding Reinforcement layer aramid 1414 fiber (D). Multifunctional epoxy resin is injected into the outermost fiber braided reinforcement layer of aramid 1414 fiber (D). The four-layer structure is cured and molded at the same time. Its Tg value reaches above 210°C. The continuous length of the rod is It is 300~5000m. The beneficial effects are: giving the sucker rod excellent temperature resistance and eccentric wear resistance, excellent radial and axial compression resistance, smaller winding diameter, high production efficiency of one-time molded products, easy operation, and high performance Stablize.

Description

technical field [0001] The invention relates to a continuous sucker rod, a preparation device and a method, in particular to a high-temperature resistant carbon fiber reinforced composite material continuous sucker rod, a preparation device and a method. Background technique [0002] Due to the increasingly complex types of developed reservoirs, the continuous increase of well depth and the continuous deterioration of the well and mine environment, the problems of corrosion and eccentric wear have become problems that need to be solved urgently in the oil production process of oilfields. Because of its light weight, high strength and corrosion resistance, composite sucker rods have gradually replaced traditional metal sucker rods. The composite material sucker rods currently used mainly include two categories: glass fiber reinforced plastic sucker rods and carbon fiber reinforced composite continuous sucker rods. FRP sucker rods are prepared by pultrusion of glass fiber rei...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to address the above-mentioned defects in the prior art, to provide a high-temperature-resistant carbon fiber reinforced composite material continuous sucker rod and its preparation device and method, so as to solve the problems of corrosion and eccentric wear in the production of oil fields, and to solve the problem of high-temperature well flushing. The main purpose is to solve the problem of oil production in deep wells and ultra-deep wells, and to prepare sucker rods with good corrosion resistance and partial wear resistance, small piston effect, and easy operation and use.
