Abstract:

The oil shale resources,which buried in 500~1 500 m,are about 6 813×108 t tones in China. The in-situ conversion
process(ICP)is still in its infancy in China and were preliminary studied by oil shale pyrolysis,micropores and permeability
experiments in different temperature. The oil shale pyrolysis is classified as 3 stages:dehydration,pyrolysis and mineral
decomposition. During these stages,the physical and chemical reaction occurred in different,micropores and permeability of
oil shale were evolved in different extent,of which the major changed is pyrolysis stage. We studied the temperature distribution
of ICP with the unsteady mathematical model. It shows that the shale oil productions can begin after 5 years heating,the duration
of productions maintains at least 2 years.
