The freezing blockage is caused by that wax in the oil gas flow can be separated out to form a mixture which is adhered to the inner wall of the pipeline in a low-temperature environment, and vapor in a gaseous state in the oil gas flow can be condensed in the pipeline in a low-temperature high-pressure environment to generate hydrate and deposit the hydrate in the pipeline. Along with the generation of hydrate and the precipitation of wax, the inner diameter of the pipeline is gradually reduced, so that the resistance of oil and gas flow is increased, the productivity of an oil and gas well is reduced, and even the pipeline channel is blocked when serious, so that the production of the oil and gas well is stopped. At present, the prevention and treatment of freeze blocking mainly comprise two aspects, namely, the generation of hydrate is reduced by adding hydrate inhibitors such as ethylene glycol and methanol; and secondly, an electric tracing band is wound outside the pipeline, and the temperature in the pipeline is increased through heat energy converted from electric energy.
