摘要

The study of each part of petroleum system is necessary.However,recently,petroleum geologists focused their attention on the study of source rock, migration and accumulation with use of different geochemical methods.Of these,carbon isotope and biomarkers or chemical fossils are new scopes in petroleum geology especially in correlation.The member 1 of Gachsaran formation can be divided into 6 keybeds,among them the B keybed is
