摘　　要：针对泥巴山隧道结构构造特点,研究和分析了该隧道的测井响应特征,结合不同岩性的测井曲线特征对其基岩岩性进行了划分,同时利用声波测井、井径测井等方法对泥巴山隧道的构造裂缝进行了识别,并利用裂缝的测井解释成果,建立了该区裂缝孔隙度地质模型。According to Nibashan Tunnel structural characteristics, this paper studies and analyzes logging response characteristics of this tunnel, and divides bedrock lithology combined with the characteristics of different rock logging curves. It simultaneously identifies structural fracture of Nibashan Tunnel with sound wave logging and caliper logging and establishes geological model of fracture porosity in this area with fracture logging explanation result.

关 键 词：测井响应 构造裂隙 裂缝孔隙度
