摘要
东海西湖凹陷的储层砂岩为下第三系平湖组和花港组砂岩,砂岩中的次生矿物为自生高岭石、次生加大石英、碳酸盐类、绿泥石和伊利石,其存在对储层砂岩的孔渗条件有影响。
The reservior sandstones of Xihu Sag in East China Sea shelf Basin belong to Pinghu and Huagang Formations of Eocene-Oligocene. In these sandstones, the secondary minerals
mainly are Kaolinite, overgrown quitz, carbonate cements, Chlorite, Illite and they have played an important role in the porosity and permeability prdperty of the reservior sandstones.
