摘　　要：针对地震资料全三维精细构造解释问题,首先对相干数据体解释断层进行分析,在此基础上,对全三维自动追踪解释断层问题进行探讨,最后,对变速做图技术进行深入研究,为推动我国地震资料全三维精细结构解释技术的进一步发展奠定基础。研究表明:通过分析相干数据体以此实现断层的自动和半自动解释,可以理清目标区域中的断层系统,在引入全三维追踪层位技术以后,可以对目标层进行全面解释,对于地震波的传播速度而言,其将会随着岩性横向或者纵向的变化而变化,因此,在将T0图转化为深度构造图的过程中,可以引入变速做图技术,进而可以得到准确的地质构造信息,为井位的合理部署奠定基础。In response to the problem of fully three-dimensionalfine structure interpretation of seismic data,this study first analyzes the interpretation of faults in coherent data volumes.Based on this,the problem of fully three-dimensional automatic tracking and interpretation of faults is discussed.Finally,in-depth research is conducted on variable speed mapping technology,laying a foundation for promoting the further development of fully three-dimensionalfine structure interpretation technology of seismic data in China.Research has shown that by analyzing coherent data volumes to achieve automatic and semi-automatic interpretation of faults,the fault system in the target area can be clarified.With the introduction of full 3D tracking layer technology,the target layer can be comprehensively explained.As for the propagation speed of seismic waves,it will change with the lateral or vertical changes of lithology.Therefore,in the process of converting T0 maps into depth structural maps,Variable speed mapping technology can be introduced to obtain accurate geological structure information,laying the foundation for the rational deployment of well locations.
