摘　　要：There are many results of single mineral enrichment characteristic, such as oil, gas, coal and uranium, but little is known about the synergistic research of these important minerals and the study of uranium enrichment features in the deep basin. So, the study on the paragenesis regularity and coexisting relation of many minerals in the basin will promote the integrated forecast and cooperative exploitation of the basin. Based on the plentiful logging data and geological data, this paper studies the distributing feature of higher Gamma abnormality. The analysis on 33 core samples' test results indicates that the increasing of Gamma abnormality is due to the increasing of the uranium element, and the enrichment of uranium is a result of the activation and conglomeration of uranium. On the basis of the recognization of radioactive abnormality and the study about the reality of oil,gas,coal or uranium coexisting in a basin and its mechanism, the paper shows that there is a certain mutual promotion in oil, gas, coal and uranium in the basin, which provides an important theory basis for cooperative exploitation of energy resources.
