Over the years, China's petroleum exploration and development has maintained a strong momentum, and at the same time it has brought a huge market for petroleum cables. For example, according to the "Twelfth Five-Year" plan, optimize the layout of energy development and strengthen the construction of energy transmission channels. Stabilize oil and increase gas, promote the formation of five large-scale oil and gas production areas in Tarim and Junggar Basin, Songliao Basin, Ordos Basin, Bohai Bay Basin, and Sichuan Basin, accelerate the exploration and development of offshore waters and deep-water oil and gas fields, and increase the extraction and utilization of coalbed methane in coal mining areas , Appropriately increase refining capacity. Coordinate the construction of natural gas import pipelines, liquefied natural gas receiving stations, cross-regional backbone gas transmission networks and gas distribution networks, and initially form a gas supply pattern for the coordinated development of natural gas, coal-bed methane, and coal-to-gas. The "Twelfth Five-Year" China's petroleum and petrochemical industries have made a good start. The economic growth structure has been further optimized, the benefits have been further improved, and the operation quality has been further improved, which has strongly promoted the development of my country's wire and cable industry.
  
   However, there are only a handful of wire and cable manufacturers in my country that specialize in R&D and production of cables for use. Mass-produced products include medium and deep well logging cables, submersible pump cables, etc. Trial-produced ultra-deep well logging cables, high-temperature oil pump cables, submersible halogen pump cables, small-diameter logging cables, integrated logging cables, perforation cables, heating cables, electrode system (also known as bridle head) cables, and ultrasonic oil production Cables, etc., which are likely to be mass-produced will be ultrasonic oil production cables, perforated cables and heating cables. Among these petroleum cables, special cables, perforated cables, and heating cables are used frequently and more carefully.
  
Heating cables are generally used in oil wells with high wax content. At the beginning, oil wells in some areas of Daqing Oilfield could not block oil due to high wax content. Heating was adopted to improve oil fluidity in high-viscosity oil wells. Heating cables are also used. Early heating cables were made of aluminum core aluminum sheath and polyester film for insulation. The aluminum sheath is prone to pinholes in the length of 1000m, causing insulation damage. The heating cables currently in use are also double steel wire armored types. There is also a story about its promotion. It is said that in a winter in the early 1980s, the weather was very cold, and many oil wells in Daqing Oilfield were blocked by wax and could not produce oil. The polypropylene insulated and double steel wire armored heating cable was designed for emergency, and the effect was very good after being used in the well site, so this structure was promoted.
  
   The cable is three-core, its purpose is to balance the three-phase power supply circuit, the cross-section is 6mm2, the voltage is 0.6/1kV, the long-term working temperature of the cable is 90℃, the environmental pressure is not more than 250kg/cm2, and the outer diameter of the cable is not more than 16.0mm. With the application of heating cables, the central sucker rod of the kowtow machine produced in Jilin was changed to a hollow tube, and the heating cable was fixed in the sucker rod of the kowtow machine, which facilitated the use of the heating cable. The use of heating cables in oil fields is in the ascendant, from three cores to single cores. This is a very promising variety. If each kowtow machine is equipped with heating cables, the number is very considerable. In addition, the cable is similar in structure to the logging cable, but with a larger cross-section, it can also be used for perforation. Note that it cannot be tested on the plate.
  
   All in all, petroleum cables are of decisive significance both in terms of the development of cable manufacturers and the development of China’s petroleum industry. At present, in view of the fact that there are few domestic companies specializing in research and development and production of petroleum cables, some powerful large-scale enterprises may wish to spend more time and effort on petroleum cables to expand the market and better serve the petroleum industry. .
