【摘要】 利用综合地球物理测井技术测得跨川西安宁河断裂带冕宁—西昌段两个钻孔的电阻率、声波速度、自然电位、自然伽马等4种综合测井曲线,并结合钻孔取芯资料得到了钻孔周围所钻遇岩土层的综合物性参数.本文得到的综合测井解释成果客观真实地反映了安宁河断裂带东、西两盘的介质物性和岩性特征,揭示了断层东、西两盘地层的纵波速度变化、视电阻率值等物性变化特征,为研究安宁河断裂带的物质组成、介质物性、断层结构及其活动状态提供了基础资料.综合地球物理测井技术有望成为监测活动断裂带附近介质物性参数动态变化的一种新手段.更多还原

【Abstract】 Using the integrated geophysical logging technique,we measured resistivity,sonic velocity,spontaneous potential and natural gamma logs of two wells which were located in Mianning--Xichang segment of Anninghe fault in western Sichuan,and obtained the integrated physical parameters combining with coring data drilled around the drilled rock layer.The integrated logging interpretation results reflect the physical properties and lithological characteristics of the east and west sets of the Anninghe fault zone objectively,and reveal the physical properties variation of the P-wave velocity and the apparent resistivity of the fault zone,providing the basic data for research on materialcomposition,media properties,structure and active state of the fault zone.Integrated geophysical logging technology is expected to become a new mean of monitoring dynamic variation of physical parameters near active fault zones.更多还原
