Carbon Fiber Composite Heating Rod

Abstract

A carbon fiber composite heating rod is composed of a heating rod body, a heating rod head end connector and a heating rod terminal connector. The heating rod body comprises a hollow sucker rod, a high-temperature-resisting insulator I, a copper conductor and a high-temperature-resisting insulation sealing ring. The two ends of the copper conductor are connected with a rapid connector male end and a rapid connector female end. The hollow sucker rod is provided with a male buckle and a female buckle. The copper conductor is wound by a carbon fiber heating wire insulated from the copper conductor. The head end of the carbon fiber heating wire is connected to the copper conductor corresponding to the rapid connector male end, and the tail end of the carbon fiber heating wire is connected with a conductor on the inner wall of the hollow rod. The heating rod head end connector comprises a rainproof junction box, a hollow rod female buckle pup joint, a high-temperature-resisting insulator II, a head end copper conductor, a conductor rapid connector female end, a copper conductor electrode binding post A, a hollow rod conductor electrode binding post B, a cable external connection control output end A and a cable external connection control output end B. The heating rod terminal connector comprises a hollow rod pup joint, a high-temperature-resisting insulator III and a high-temperature-resisting insulating sealing ring.

Description

technical field [0001] The invention relates to a carbon fiber composite heating rod used in oil extraction operations. Background technique [0002] At present, most of the hollow rods for oil production are heated by intermediate frequency heating, that is, the whole steel armored skin heating cable is continuously lowered into the hollow rod, and finally the cable is fixed on the top of the hollow rod, and connected to the intermediate frequency power control device with the cable, and the power is supplied through the device Make the skin cable heat, and then pass to the hollow rod, and the hollow rod will transfer the heat to the crude oil outside the hollow rod. Due to the heavy weight of the cable itself, it has to bear its own weight, which often causes the cable to break during operation; at the same time, because the cable is located in the hollow rod, it will rub against the inner wall of the hollow rod during the up and down operation of the hollow rod, which tak...

Problems solved by technology

Due to the heavy weight of the cable itself, it has to bear its own weight, which often causes the cable to break during operation; at the same time, because the cable is located in the hollow rod, it will rub against the inner wall of the hollow rod during the up and down operation of the hollow rod, which takes a long time It is easy to be worn and damaged; in addition, due to high current heating, when the steel armor of the cable is thinned, it will cause severe heat, which will easily cause the cable to be broken down and damaged, so the cable has a high failure rate and a short service life. , generally within 1-2 years, some even within a few months; and special engineering vehicles and personnel have to be used for lifting and lowering cables, resulting in high maintenance costs
