Research status and development trend of thermal insulated tubing technology for deep geothermal energy development
Abstract:Geothermal energy is a kind of clean and renewable energy. Replacing high carbon energy with geothermal energy is one of the effective ways to reduce carbon emission.Underground pipe insulation technology is one of the key technologies that influence efficiency of geothermal energy exploitation. The development of the underground thermal insulation pipe production technology research present situation is introduced,which contains the insulation tube structure, materials, insulation materials, and production process.The blend of nano insulation materials and vacuum tubing will be the development trend in the future.And vacuum nano insulated tubing being used in the deep geothermal energy exploitation will be the first choice.At the same time,it is pointed out that the influence mechanism of basic structure factors on thermal insulation performance of vacuum nano insulated tubing is the focus of research, which has guiding significance to optimize the production process of thermal insulation tube, reduce cost and increase efficiency.
