Abstract

The industrialization of various countries has promoted the continuous consumption of energy, which has led to increasing demand, and shale oil has been gradually explored and utilized by the public as a substitute for oil. As the mainstream technology in oil shale mining, in-situ mining heating technology is widely used. A new oil shale development technique is introduced in response to the low energy utilization rate of in-situ mining heating technology. Oil shale's tiny, carbonized channels are immediately penetrated by voltage in the power heating technology, which then heats the oil shale to pyrolyze it. This article uses simulation software to establish a coupled model, obtains the temperature distribution and potential distribution of oil shale through numerical calculation, and analyzes and compares it with traditional in-situ mining techniques. According to the findings, power supply heating has a 32.4% greater heating rate than traditional heating, a 27-fold increase in the effective heating volume, a faster heating rate, and a higher energy utilization rate.
