| 摘 要： | 杭州湾盆地系浙江地区唯一有第三系分布的沉积盆地,含第三系、白垩系及古生界三个找油层系。钻井揭示长河凹陷下第三系储层中存在高成熟液态烃现象。热模拟试验证实下第三系暗色泥岩具有生气能力。长河凹陷杭19井周围浅层低幅构造及杭17井附近老新街构造是有利油气聚集部位。平湖凹陷杭4井周围有10km~2的白垩系储气层。桐乡凹陷中部重力高、王盘洋凹陷次隆部位等可能是寻找古生界油气藏的目标区。

| Abstract: | It is the only basin in which there is the distribution of Tertiary in Zhejiang region.The Hangzhou Estuary Basin possesses three series of strata for exploration,i.e.Ter- tiary,Cretaceous and Paleozoic.Drilling shows that there is high-matured liquid hydrocarbon in the Paleogene of Changhe Sag;the experiment of thermal simulation verify that the Paleogene dark mudstone has gas-generating abili- ty.There are two advantageous oil-and gas-gathering places in the Changhe Sag,the low-amplitude structure around Hang-11 well and Laoxinjie structure near Hang- 17 well;there is about 10km~2 of Cretaceous gas-bearing- stratum around Hang-4 well,Pinghu Sag;both the high gravitational region at the center of Tongxiang Sag and the second-order uplift in Wangpanyang Sag are the targets for Paleozoic oil and gas reservoirs. |
