摘要
西湖凹陷平湖构造带始新统平湖组可划分出潮坪沉积相和潮汐三角洲沉积相2种主要的沉积相类型,潮间带、潮下带、三角洲前缘和前三角洲等4种主要的沉积亚相及微相。该区有利储集相带主要有潮道、潮坪砂坝、河口坝及前缘席状砂微相。
Eocene Pinghu Formation in the studied area can be divided into two main sedimentary types, consisting of tide-flat sedimentary facies and tidal delta sedimentary facies, and four subfacies including intertidal zone, subtidal zone, delta front and prodelta and several microfacies. Tidal channel, tidal-flat bar, river mouth bar and front sheet-like sand microfacies are main favorable reservoir belts in the area.
