In the global energy accelerated transformation,China's new energy transformation in the critical period of comprehensive promotion,reducing fossil energy consumption bear the brunt of.At present,the consumption of fossil energy in the production process of domestic oil fields is generally relatively high,and they are actively carrying out green and low-carbon transformation development.Molten salt energy stor-age technology is a technology that uses the characteristics of molten salt,such as high heat capacity,high decomposition temperature,high fluidity and low corrosiveness,and uses it as a heat storage medium to store valley electricity or green electricity in the form of heat,and then releases heat from the stored heat for industrial production.The technology has been widely used in solar thermal power generation,peak regu-lation and frequency regulation of thermal generating units,heating and waste heat recovery and utilization.At present,the research on molten salt heat storage technology is generally centered on solar solar thermal power generation,exploring how molten salt heat storage technology can be applied in oilfield production systems,analyzing physical properties of molten salt,studying its heat storage temperature range,appropriate heating methods,key equipment components and system process flow,etc.,so as to realize the storage and release cycle of molten salt with relatively low valley electric heating.It is of great significance to meet the demand of oilfield production heating,improve the level of oil field green electricity consumption,and reduce fossil energy consumption for the realization of the"double carbon"goal.
