摘要:
为了加深对盆地深部和浅部高自然伽马异常特征综合分析研究,揭示高自然伽马异常地质成因,从而 促进盆地多种能源矿产协同开发研究,针对收集大量的地球物理测井资料、地质资料及其他相关成果,绘制并分 析了相关成果图。研究中遵循从单孔测井曲线特征分析到典型剖面研究,并按层对高自然伽马的平面分布特征 进行分析研究。化验测试结果和自然伽马能谱测井成果研究表明,在本区,自然伽马异常增大主要是由于铀的 活化和聚集,导致铀元素增加而引起。相关研究表明,盆地深部和浅部的铀异常具有一定的关系,盆地历经的沉 积环境变迁是铀元素富集的主导因素。
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.
