【摘要】 AVO正演模型与AVO交会分析在AVO技术中占有十分重要的位置。以岩石物理理论为基础,根据MXG地区测井资料和其他相关信息,通过流体替代分析了不同深度条件下天然气饱和度对岩石属性的影响;并利用地震正演模拟及AVO交会分析技术研究了不同条件下天然气饱和度对地震反射特征的影响。其结论和认识可为利用地震AVO分析储层天然气饱和度提供理论基础。更多还原

【Abstract】 AVO forward model and AVO intersection analyses were important in AVO technology.On the basis of rock physical theory,logging data and other relevant information,by fluid substitution,the effect of natural gas saturation on rock attribute under different conditions was analyzed,the techniques of seismic forward modeling and AVO intersection were used to study the effect of natural gas saturation on seismic reflection characteristics under different conditions.The results and understanding provide a theoretical evidence for analyzing gas saturation by using AVO.更多还原
