OIL SHALE EXPLOITATION METHOD AND DEVICE

摘要

Disclosed is an oil shale exploitation method, comprising: forming a first channel reaching the ground surface in the oil shale; forming a second channel reaching the ground surface from a coal layer located under the oil shale and a third channel that communicates with the second channel and reaches the ground surface from the coal layer; performing underground gasification on the coal layer to form a combustion cavity; and collecting oil and gas. Further provided is an oil shale exploitation device, the coal layer being located under the oil shale. The device comprises: a first channel disposed in the oil shale and reaching the ground surface from the oil shale; a second channel disposed in the coal layer and reaching the ground surface from the coal layer, the first channel being located above the second channel; and a third channel that communicates with the second channel and reaches the ground surface from the coal layer. According to the present invention, not only the energy utilization is increased, but also an artificial heat source is not required to implement gas preparation through in-situ dry distillation of oil shale.
