Abstract

The invention relates to equipment for improving the plasticity of a coiled tubing by heating a roller through new energy power supply and a method, and belongs to the technical field of heating equipment on a petroleum drilling and production well. The equipment a rack, the roller and a heating coil, the roller is movably installed on the rack through a center shaft, the heating coil is arranged on the inner wall of the roller, a storage battery is arranged at one side of the roller and electrically connected with the heating coil, and a solar power supply mechanism is arranged above the roller and connected with the center shaft. Wind energy power supply mechanisms are symmetrically arranged at the two sides of the solar power supply mechanism correspondingly and connected with the center shaft. Heating equipment is convenient to assemble and disassemble, the storage battery is supplemented with electric energy through the solar power supply mechanism and the wind energy power supply mechanisms, the storage battery provides electric energy for the heating coil, the heating coil directly heats the coiled tubing on site, the plasticity of the coiled tubing is improved, and therefore the service life of the coiled tubing is prolonged.

Description

technical field [0001] The invention relates to a device and a method for improving the plasticity of coiled tubing by using a heating roller powered by new energy, and belongs to the technical field of heating equipment on oil drilling and production wells. Background technique [0002] The application of coiled tubing technology in oil and gas field drilling, well completion, oil production, well washing and other fields is increasing day by day, and it is playing an increasingly important role in the petroleum field, enjoying the reputation of "universal operation equipment". Coiled tubing needs to transmit axial force in downhole operations. The higher the stiffness, the farther the axial force can be transmitted. However, the coiled tubing is bent and deformed when it is wound on the drum. If the plasticity of coiled tubing can be increased, the fatigue life of coiled tubing can be improved. [0003] At present, experts and scholars have carried out a lot of research wo...

Problems solved by technology

[0004] Therefore, many companies and research institutions improve the plasticity of coiled tubing by improving the processing technology of coiled tubing from the aspect of material manufacturing, so as to increase the service life of coiled tubing; even so, every complete operation process of coiled tubing must be After going through the cyclic bending stage under pressure, under some complex working conditions on site, the coiled tubing body will still exceed the yield strength of the material during the working process, and a wide range of plastic deformation will occur, thereby accelerating the fatigue damage process and resulting in a low service life. Therefore, it is necessary to heat the drum by means of new energy sources such as solar energy and wind energy to improve the plasticity of the coiled tubing, thereby increasing the life of the coiled tubing
