[0009] detailed description Using the pultrusion molding process, the multi-bundle carbon fiber is impregnated with epoxy resin glue and the composite glass fiber thermoplastic belt enters the pultrusion molding machine, and the gel is rapidly cured in the preheating zone and the molding curing zone of the pultrusion molding machine, and then passed through the pultrusion molding machine. The traction coil is wound onto the disc, and the production process is completed.

A novel carbon-fibre composite sucker rod comprises carbon fiber and epoxy resin, and the novel carbon-fiber composite sucker rod is characterized in that glass fiber thermoplastic is added, and the novel carbon-fiber composite sucker rod is composed of the following components in wt%: 72% of carbon fiber, 1% of glass fiber thermoplastic, and 27% of epoxy resin glue liquid. The invention possesses strong tensile strength, strong anti-fatigue capability, high wear resistance, light weight, and a high ratio of intensity and weight, simultaneously, the production process is simplified, and production cost is reduced.
Description
technical field [0001] The invention belongs to the field of oil exploitation equipment, and in particular relates to a novel carbon fiber composite sucker rod. Background technique [0002] The sucker rod is a slender member of the pumping well, it is connected to the main rod at the top, and the pump is connected at the bottom to transmit power. Sucker rods are generally made of high carbon steel with hard chrome plating on the surface, and are connected one by one with internal threaded hoops in the oil pipe until they extend to the piston at the underground oil layer, and the oil is pumped through reciprocating motion. Currently, the length of oil wells is generally about 2,000 meters. Taking Shengli Oilfield as an example, the deepest one is more than 3,000 meters. [0003] At present, the common sucker rods are mostly made of steel or glass fiber reinforced plastics. The disadvantage is that these two materials are rigid materials with poor tensile strength and fatig...
