Abstract��

Heating the oil shale by current underground to accomplish in-situ transformation process��is a viable direction�� The electrical properties of oil shale under different temperatures��especially the resistance��become important�� Charging oil shale underground to heat oil shale till kerogen's decomposition temperature��then crude oil and other gases can be generated�� The resistance of the oil shale samples was measured by Direct Current ( DC) quadripole method to find out the variation rules of resistance value�� In the experiments��oil shale presented its semiconductor property�� When heated till 350��-450�棬its resistance changed greatly��optional for heating and cracking�� The porosity��oil content��media and composition affected the resistance largely��
