摘要:

二叠系以海相碳酸盐岩地层为主,是四川盆地的重要产气层之一。作者对33条剖面进行了系统的工作,在取得丰富牙形石资料的基础上,对该区二叠系的地层划分与对比,二叠系至三叠系底部的Neogondolella和Anchignathodus属的演化系列,沉积相与牙形石的关系,和根据上二叠统牙形石色变判断上三叠统油气成熟度指标等进行研究

Abstract:

The Permian is dominated by marine carbonate,which is a major zone of gas production in the' Sichuan, basin. Thirty three formation sections have been systematically studied and numerous data of conodonts have been collected. The Paper describes the author’s recent research results. According to the vertical and lateral distribution of conodonts discovered,ten conodont zones can be divided. A sequence of the evolution of Permian Neogondolella .And Ahchignathodus genus and the relationship of conodont color to the estimation of oil arid gas maturity are found.
