摘要
页岩的地球物理特征研究表明,页岩的地震特征主要表现在页岩地震响应的复杂性、各向异性和相干性;页岩的地球物理测井响应特点则包括常规的测井响应特征和特殊测井响应特征。页岩的常规测井曲线响应特征表现为高伽马、高声波时差、高电阻、低密度、井径扩大等,而特殊测井响应特点则表现在能够更准确的识别页岩,并能够获得更多的基础数据来计算相关参数。
Based on the previous researches,this paper summers up the geophysical characteristics of shale,which include common response of geophysical logging.The study indicates that the main features of the seismic of shale are complex,anisotropy and coherent.The characteristics of geophysical logging responses include conventional response and special logging response.The features of conventional logging response show high gamma,high acoustic time,low density and hole enlargement.The characteristics of response of special logging reflect in identifying the shale reservoir is more accurate,and obtaining more basic data to calculate the relevant parameters. The applying of the geophysical characteristics of shale correctly can play an important guiding role in shale exploration and exploitation.
