摘要
西湖凹陷位于东海陆架盆地东北部，始新统平湖组是该地区重要目的层，本文针对平湖组主力含油气储层的四个成因类型；潮道、潮汐分流河道、分流河道、河口坝-前缘席状砂的岩石学、沉积学特征分析，预测砂体形态并对各类储层性质逐一评价。
Xihu Trough is located at the east - northem East China Sea shelf basin, and Pinghu Forma tion (Eocene) is the key target in the basin. This paper gives lithological and depositional analyses to four main genetic oil/gas reservoirs of Pinghu Formation including tidal channel, tidal distributary channel, dis tributaly channel and mouth bar - front sheet sand, forecasts these reservoirs shape and makes a review on physital propenies of all reservoirs.
