摘　　要：介绍地震瞬时属性分析技术的原理及处理方法,分别对岩溶在地震剖面、瞬时振幅剖面、瞬时频率剖面、瞬时相位剖面上的表现特征作了说明。并结合实际资料进行多参数解释,进而确定地下岩溶的发育情况、分布范围和规模,同时对异常进行钻井验证,结果表明,地震瞬时属性分析技术比常规地震处理方法能更好地排除干扰,确定岩溶异常。The paper introduces the principle of the seismic instantaneous attributes,and illustrates the features of karst in the seismic section,the instantaneous amplitude section,the instantaneous frequency section and the instantaneous phase section.Combined with the multi-parameter interpretation of real data,the developed situation,distribution scope and scale of the underground cabstand can be determined and validated the outcomes by making use of Well Drilling.The results show that the seismic instantaneous attributes can be better to eliminate disturbance and estimate karst anomaly than that with the conventional seismic data processing methods.
