【摘要】 基于角度交会的振幅随偏移距变化(AVO)分析原理,对四川M气藏的多种叠前AVO反演属性进行综合研究。结果表明:独特角度交会方法比传统AVO交会方法能更好地区分AVO异常;独特颜色编码的交会方式可以定量预测储层流体的分布,大大提高AVO属性解释的能力;独特角度交会方法可应用到叠后地震属性和多种测井曲线的交会中,为地震属性的优化和地质解释提供新的思路和方法。更多还原

【Abstract】 Based on the angle crossplotting theory,pre-stack AVO attributes were used to analyze M gas field in Sichuang.The results show that AVO angle crossplotting is better to differentiate anomaly from background data than conventional method,and the unique color coding method can quantitatively characterize distribution of fluid,which can greatly improve the ability of AVO interpretation.This technique can also be applied to crossplot post-stack seismic attributes or well logging data,which provides a new way for seismic attributes optimization and geological interpretation.更多还原
