Abstract:
For the purpose of deepening synthesizing researches on deep and shallow abnormality of natural gamma and its geological genesis in Ordos basin, and in order to advocate co-exploitation to multi kinds of energy sources and minerals in Ordos basin, this paper collects rich data in logging, geology and other aspects, production fig- ures are carefully plotted and researched. This paper studied from single well to representative sections, and then analyzed the plane features according to layers. The test results show that the increasing of abnormal natural gamma comes mainly from the increasing of uranium. The activation and accumulation aroused the abnormity of natural gamma. There is a certain correlation in shallow and deep abnormality of uranium. The variance of sedi- ment environment is the leading factor for the uranium accumulation.
