Application Prospects in China of Oil Shale In Situ Mining Method and an Improved Method

Abstract:

Oil shale resources is a new energy has a huge potential for development, as the complement and alternative energy of the oil and gas, more and more people pay attention to it. China's oil shale resources are widely distributed and reserves are huge, but current mining methods are still primitive, mainly to direct exploitation, exploitation efficiency is low and ecological damage is serious, it will be replaced by in-situ mining methods in the future. This paper summarizes the research of oil shale in situ mining, aims at the problems of that the conduction of heat efficiency is low and the outlet channel is less which exist in the in-situ mining at the present, and put forward the concept of in-situ broken that is using some methods to make the oil shale change from huge to small block in the initial stage of the in-situmining, further in-situ heating, mining of oil shale，and put forward the method of in-situ noncontact wind breaking oil shale, this method using the crushing wind to break the oil shale, having high feasibility. This paper did in-depth research on the in-situ mining, and it can provide a reference for the development and utilization of oil shale resources.
