摘　　要：文章阐述了二连盆地腾格尔坳陷主要地区岩石的地球物理测井物性特征,数据表明综合测井曲线对不同粒级岩性的响应效果佳,尤其是视电阻率曲线-自然电位曲线组合识别效果较好,这些为该地区沉积环境分析提供了很好的物性前提和依据。不同的岩性在测井曲线上有不同的响应特征,特定的岩石组合和垂向序列会形成特定的测井组合形态。据此,分析和总结了不同沉积环境下的测井相特征及对应的沉积微相,有助于提升该地区铀成矿规律的研究认识水平,为本区的找矿突破提供指导作用。This paper describes the geophysical logging physical characteristics of rocks in the main areas of Tengger depression in Erlian basin.The data shows that the comprehensive logging curve has a good response to different grain size lithology,especially the combination of apparent resistivity curve and spontaneous potential curve has a good recognition effect,which provides a good physical property premise and basis for the analysis of the sedimentary environment in this area.Different lithology has different response characteristics on logging curve,and specific rock combination and vertical sequence will form specific logging combination shape.Based on this,the characteristics of logging facies and corresponding sedimentary microfacies under different sedimentary environments are analyzed and summarized,which will help to improve the research and understanding level of uranium mineralization law in Tengger depression and provide guidance for the exploration breakthrough in this area.
