Study On Cost Management and Energy Efficiency Promotion Strategy of Geothermal Clean Heating System
With the adjustment of national energy structure and the promotion of energy conservation and emission reduction policies in China, the geothermal clean heating industry has a very broad space for development. At present, China's geothermal development and utilization system has accumulated certain successful experience in district heating. The biggest problem of geothermal heating at present is the low utilization rate of heat energy, which greatly wastes geothermal resources. Based on this, this paper takes the middle and deep geothermal district heating system as the object, and dissects the cost structure and improvement control measures of geothermal district heating. This paper focuses on the methods to improve the energy efficiency utilization level of geothermal district heating system from six aspects, including the selection of resource target strata, drilling and completion technology, process design and construction, pipeline network routing design, production and operation management, and user end. Finally, this article analyzes the problems that need to be paid attention to in the technology, safety, economy, and operation of geothermal district heating system development and utilization. This work will help to improve the utilization efficiency of geothermal resources systematically, and provide reference for the implementation of comprehensive utilization project of geothermal district heating system in the future.
