High strength lightweight carbon fiber composite sucker rod

The composite carbon fiber sucker rod is suitable for harsh well environments in oilfield development, including deep wells, ultra-deep wells, corrosive wells, and unevenly worn wells. It is formed by pultrusion curing of continuous carbon fiber, glass fiber, and epoxy resin. Compared to traditional steel sucker rods, the carbon fiber composite structure is lighter, more corrosion-resistant, and has stronger fatigue resistance.   Technical Principles   Processing Flow: After resin preforming, the material is fed into a mold, heated and cured, and then wound onto a winding reel using a traction machine. The process fully utilizes the slender shape of carbon fiber, its convenient impregnation, and ease of cross-linking to achieve continuous production of linear composite material products from carbon fiber and other raw materials.   Installation Structure: The carbon fiber continuous sucker rod downhole tubing mainly consists of four components: a special connector, a safety joint, a sw…
