Abstract

Rational and efficient development of oil shale resources is of strategic significance for energy security and economic development of China. The underground in-situ conversion technology of oil shale had unique advantages compared with surface destructive distillation technology, providing a new direction for oil shale exploitation in the future. In this paper, the development status of underground in-situ conversion technology of typical oil shale was systematically analyzed, and the process characteristics were summarized, such as electric conduction heating, thermal fluid heating, radiation heating and combustion heating. Combined with existing studies, the next study targets were proposed from the aspects of reservoir fracturing, underground reservoir space closure, efficient heating and new energy applications. The study can provide technical reference for green and efficient exploitation of oil shale.

Key words： oil shale; in-situ conversion technology; electrical conduction heating; thermal fluid heating; radiation heating; combustion heating
