| 摘 要： | 浙西及皖南地区下古生界广泛分布的碳沥青是石油高热演化的产物。通过对碳沥青的生源母质研究和油源对比,证实了本地区至少存在上震旦统、下寒武统和奥陶系三套烃源岩,其中下寒武统黑色页岩和腐泥煤是主要生油岩系。不同地区的碳沥青热演化程度不等,属于湿气晚期至干气的热演化阶段,天然气资源丰富,是寻找早古生代原生气藏的有利地区。

| Abstract: | The carbonaceous bitumen widely distributed in the lowerPaleozoic in western Zhejiang and southern Anhui provinces is the result of petroleum thermal evolution.The study on bitumen source matter and the correlation between petroleum and the source rocks show that there are at least three series of source rocks in the areas,namely pre-Cambrian,lower-Cambrian and Ordovician.Among them the black shale and the sapropelic coal of lower-Cambrian are the main source rocks.The degree of petroleum thermal evolution varies from place to place.It is in the stage of late wet gas and dry gas thermal evolution.These areas are rich in natural gas sources and are promising arees to find pre-Cambrian primary natural gas pools in the L-Cambrian. |
