Abstract

The invention relates to a high-temperature-resisting carbon fiber reinforced composite continuous sucker rod and a preparing device and method. According to the technical scheme, reinforced fiber carbon fiber (A) and fiber winding reinforced layer aramid fiber 1414 fiber (B) in the axial direction of a rod body are sequentially arranged from interior to exterior; and reinforced fiber high-strength glass fiber (C) and fiber weaving reinforced layer aramid fiber 1414 fiber (D) are arranged in the axial direction of the rod body, polyfunctional group epoxy resin is injected into the exterior of the outermost fiber weaving reinforced layer aramid fiber 1414 fiber (D), and four layers of structures are solidified and formed at the same time, wherein the Tg value reaches more than 210 DEG C, and the continuous length of the manufactured rod body ranges from 300 m to 5,000m. The sucker rod has the beneficial effects that the sucker rod is endowed with superior temperature resistance, eccentric wear resistance and radial and axial pressure resistance and small winding diameter, the production efficiency of products formed at a time is high, operation is easy and convenient, and performance is stable.

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...
