The
resistivity data obtained by the rock specimen method and logging method
indicate that the organic matter-rich shale layers have relatively high even
the highest resistivity values. The detection tests in the Hehiafang oil shale
mining area and the Minhe oil gas basin mining area show that the organic
matter-rich shale layer, whether it lies at the shallow depth(shallower than
hundreds of meters) or in great depth(with buried depth of several kilometers),
can be effectively identified by the resistivity prospecting method. This paper
also points out that the resistivity prospecting method can play the role in
shale gas and oil shale exploration.
