Application of seismic sedimentology to the analysis of sedimentary system in Fudong area
Online published: 2014-06-06
Based on the comparison of traditional sedimentary system analysis methods, this paper proposed seismic sedimentology method to carry out sedimentary system analysis. On the basis of sequence stratigraphic classification, this paper carried out seismic data to 90° phase conversion, 3D seismic attribute analysis, extraction and analysis of stratigraphic section, established the corresponding relationship between seismic attribute characteristics and sedimentary facies by calibrating the seismic sedimentary facies through the observation of core and outcrops, well logging and modern sedimentary analysis, and analyzed the sedimentary system. It is considered that the seismic sedimentology sedimentary system analysis method is based on the sequence stratigraphic framework, and it can ensure the isochronous stratigraphic correlation, make full use of the lateral seismic resolution to recognize the thin layer of sand body which is difficult for the seismic vertical resolution, and combined the seismic attribute processing with sedimentology, it can predict sand body space distribution and evolution characteristics.
