南组沉积相类型、展布及其演化规律进行研究。研究认为北斜坡戴南组主要发育辫状河三角
洲、曲流河三角洲相和湖泊相。三角洲相可细分为三角洲平原、三角洲前缘和前缘三角洲亚

Abstract: With core data, logging data, analysis data and seismic data, combined with the regional
geological background,the study about sedimentary facies types,distribution and evolution of
Paleogene Dainan Formation of North Slope in Gaoyou Sag, was carried out systematically in the
sequence stratigraphic framework established with high resolution sequence
results indicate that the North Slope Dainan Formation can be divided into braided river delta
facies, meandering river delta facies and lake facies. Delta facies were divided into delta plain,
delta front and front delta facies, lacustrine facies in the north slope of main shore shallow lake
subfacies. On this basis,microfacies included in subfacies were model is
established after considering the background of the target area sediment and deposition feature,
based on sedimentary facies distribution and evolution.
Key words: sedimentary evolution; Gaoyou Sag; North Slope; Dainan Formation
