摘要：The thickness of SQ7 sand body in Shannan area is thin, the lateral variation is fast, the distribution of sedimentary sand body is not clear, and the conventional sedimentary analysis method and reservoir prediction technology can not meet the requirements of fine oil and gas exploration. On the basis of the principle and research method of seismic sedimentology, the lithologic reversion of seismic profile was carried out by using 90° phasorization, and seismic sedimentology was carried out to study the plane distribution characteristics of SQ7 sand body in this area by using the technique of stratum isochronous section. Based on the analysis of seismic attribute sections and lithologic time sections under the equivalent time frame, the temporal and spatial evolution law and sedimentary microfacies of braided river delta deposits in the southern source system of the SQ7 period in this area are revealed. The distribution of sand body is described in detail, which provides the basis of seismic deposition for oil and gas exploration and deployment.
