摘要
提出了一种有效的对常规采样方法改进的深时转换方法。其技术关键是在对测井曲线或反射系数序列进行深时转换时,将丢失的反射界面信息加回到按常规采样方法得到的序列中去。这样改进后的采样新方法不仅可记录时间信息,还可记录层位信息,并且在深时转换后会保留更多的薄层信息,使测井资料与地震资料匹配得更好。
An effective depth to time domain transforming method is presented to improve normal sample method.The key of the new method is to add lost reflection interface information to series obtained from normal sample method when well curves or reflection coefficient series are transformed from depth domain to time domain.New sample method records not only time information but also reflection interface information,which may remain thin bed information after transforming from depth domain to time domain,and make well information match seismic profile better.
