Many years’oil and gas exploration with radioactivity indicates that there is anomalous radioactivity in the sediments mantling oil deposits.However

it has not been clear that there is a relationship between the anomalous ra- dioactivity and the oil deposits.In this paper

in order to test the effect of the migration of oil and gas on the redistri- bution and enrichment of radio elements in the sediments covering on oil deposits

indoor simulating experiments on the mechanism of oil and gas exploration with thermoluminescence in superficial sediments were carried out.In the experiments

the redistribution of the elements in the superficial sediments of oil and gas deposits has been observed after excluding the factors of the difference in environmental irradiation

the motion of groundwater

landscape change and the difference in sediment.Based on previous work

the experimental results show that the assumption

"The migration of oil and gas causes radio elements in overlying sediments to redistribute"

is right.This provides theoretical and experimental basis for the method of the oil and gas exploration with thermoluminescence of superfi- cial sediments.
