【摘要】 基于实验室的岩石物理分析只能反映单一因素变化对地震特性的影响,而地震特性受到岩石的弹性模量、密度和吸收等多方面的影响,实验室岩石物理技术不能准确的分析出特定地区的地下地质情况。测井岩石物理分析技术综合分析了地下岩石、流体、温度、压力等多种因素对地震特性的影响,反映了真实的地下地质情况。通过对XC地区须家河组测井岩石物理的分析,提出了多种测井岩石物理分析方法并建立了区域性的岩石物理模版。为以后开展测井约束参数反演,利用地震数据精确识别气水提供了思路。更多还原

【Abstract】 Laboratory-based petrophysical analysis can only reflect changes in a single characteristic of the earthquake,and seismic properties of rocks by the elastic modulus,density and impact absorption,and petrophysical laboratory technology can not be accurate petrophysical analysis of specific areas underground geological conditions.Petrophysical log analysis a comprehensive analysis of the underground rock,fluid,temperature,pressure and other characteristics of a variety of factors on the impact of the earthquake,reflecting the actual geological conditions underground.XC region through Xujiahe petrophysical log analysis,put forward a variety of petrophysical log analysis and the establishment of regional petrophysical template.Carried out for future logging constrained parameter inversion using seismic data to provide accurate identification of the idea of water gas.更多还原
