众所周知时深转换是将地震数据从时间域向深度域转换,它依靠速度,向人们展示了地下的构造情况。常规的时深转换主要利用声波测井曲线和密度曲线求取速度来实现。本文主要讨论在没有精确速度场,也没有声波和密度资料的情况下如何求取深时关系。笔者通过长期调研和验证,首次提出了通过运用已知的地质分层和地震资料,在VC++和Qt环境下编程,把深度域的井数据转化到时间域内,求取井的深时关系,进而实现时深关系的求取,为后续的地质统计学建模提供准确的时深关系。
It is well-known that time-to-time conversion converts seismic data from the time domain to the depth domain and relies on the speed to show people the underground structure. The conventional time-to-depth conversion mainly uses the acoustic logging curve and the density curve to obtain the speed. This article focuses on how to find deep relationships without accurate velocity fields and acoustic and density data. Through long-term research and verification, the author first proposed that deep well-time data can be converted into deep well data by using well-known geological stratification and seismic data and programming in VC ++ and Qt environments. The realization of the relationship between depth and depth can provide accurate time-depth relationship for subsequent geostatistics modeling.
