Abstract

The X sag in the East China Sea Shelf Basin has great exploration potential and rich oil and gas resources, but the exploration degree is low, and the exploration process still faces the key geological problem of inconsistent sequence stratigraphic framework. Therefore, this study is based on regional geology, logging, seismic and analysis data, using well-seismic correlation, spectrum analysis, wavelet transform, relative sea level change analysis and other methods, through the identification of sequence boundaries of seismic and drilling at all levels, supplemented by stratigraphic sequence cycle and relative sea level change analysis. According to different sequence stratigraphic models, the Paleocene stratigraphic division scheme of X sag is determined. The Paleocene strata are divided into five third-order sequences, namely Y Formation, lower L Formation, upper L Formation, lower M Formation and upper M Formation, thirteen fourth-order sequences are further identified, which Y Formation and upper M Formation are divided into transgressive system tract and regressive system tract, the lower L Formation, upper L Formation and lower M Formation are divided into lowstand system tract, transgressive system tract and highstand system tract, and a unified stratigraphic sequence framework of the whole region is established. It provides geological support for the study of sedimentary facies and its development law under the control of Paleocene stratigraphic sequence in X sag, promoting the unification of basic geological understanding of X sag and the selection of favorable areas in the next exploration work.
