摘要

Based on the palaeogeographic background analysis, the detailed observation and description of cores, combined with the analysis of lithofacies, electro-facies and seismic facies, this study reveals that deposit of Zhuhai Formation rich in sand supplied by the Pearl River delta experienced reworking of strong tides, and is dominated by tidal sedimentation. In this paper, tidal sedimentary structure, sedimentary sequence and facies succession of inter-tidal and supratidal facies have been detailed described. The regional distribution of depositional system in the study area has been revealed based on facies analysis of single well, combined with regional seismic facies analysis. This new understanding will be favorable for oil and gas exploration and development in this area.
