提出了地震沉积相和地震沉积相模式的概念,分析了地震相和地震沉积相的差异,提出了地震沉积相分析的具体流程和方法:从地震地貌形态分析入手,在沉积模式指导下,用测井和岩心资料做标定,结合岩石物理方法,将地震沉积相转换成沉积相.以松辽盆地为例,在西部地区建立了多种地震沉积相模式,并逐一描述其特征.在此基础上,采用地震沉积相分析方法,得到了相应的沉积相图.
The concepts of seismic sedimentary facies and seismic sedimentary facies model are proposed. The differences between seismic facies and seismic sedimentary facies are analyzed. The specific processes and methods of seismic sedimentary facies analysis are proposed. Starting from the morphological analysis of seismic geomorphology, under the guidance of sedimentary model, Logging and core data are calibrated and the seismic sedimentary facies is converted into sedimentary facies in combination with petrophysical methods.With the Songliao Basin as an example, a variety of seismic sedimentary facies patterns have been established in the western region and their characteristics have been described one by one On the basis of the method of seismic sedimentary facies analysis, the corresponding sedimentary facies map is obtained.
