沉积相是在特定环境条件下形成的地质体,沉积相的研究.在石油地质研究中占有重要地位。根据国内外油气勘探表明,油气的生成与分布.均与沉积相带有密切的关系。我国陆相沉积盆地,与海相沉积盆地相比较,具有多物源,多沉积体系,相带多呈环状公布的特征。勘探实践及研究表明,沉积相带的分布与油气生成及聚集关系密切。
Sedimentary facies is the study of geological bodies and sedimentary facies formed under specific environmental conditions, and plays an important role in petroleum geological research. According to the exploration of oil and gas at home and abroad, the formation and distribution of oil and gas are closely related to the sedimentary facies. Compared with the marine sedimentary basins, the continental sedimentary basins in China have the characteristics of multi-source, multi-sedimentary systems and facies belonged to the ring. Exploration practice and research show that the distribution of sedimentary facies is closely related to hydrocarbon generation and accumulation.
