[0002] Carbon fiber continuous pumping rods are made of carbon fiber as the main reinforcement material. They have the advantages of light weight, high strength, corrosion resistance, and fatigue resistance. As the types of oil reservoirs being developed become more and more complex, the well depth continues to increase and the well mine environment continues to deteriorate, corrosion and eccentric wear problems have become problems that need to be solved in oil field production technology. Therefore, carbon fiber continuous pumping rods have begun to gradually replace traditional metal pumping rods. While giving full play to the technical advantages of carbon fiber continuous pumping rods such as deep pumping, corrosion resistance, and energy-saving lifting, in order to better realize online continuous monitoring of oil well production data, reservoir dynamics, etc., technicians have developed various composite material continuous pumping rods, which are detected and transmitted by implanting optical fibers.
