摘要(Abstract)：

北美白垩系地层是北美油气发育的主力烃源岩层之一,目前已发现多个与之相关的常规和非常规大油气田。北美白垩系烃源岩主要分布在北美西部的落基山山前带和墨西哥湾地区,岩性以页岩为主,纵向上主要有Aptian-Albian阶、Turonian阶和Campanian阶3套,有机质丰度介于1%~8%之间,有机质类型以Ⅱ2型为主,Ⅱ1型和Ⅲ型次之,以Mowry、Niobrara、Eagle Ford页岩为典型代表,大部分处于低熟-成熟阶段。落基山山前带受冲断带影响,盆地呈西气东油格局,而墨西哥湾地区则为南气北油的格局。良好烃源岩层也为非常规油气聚集区提供了大量的油气,以Eagle Ford页岩油气为典型代表。落基山北部西加盆地以地层岩性圈闭为主,中部构造圈闭和地层岩性圈闭并重,墨西哥湾地区受盐底辟作用以构造圈闭为主。在落基山山前带远离造山带一侧和墨西哥湾北侧盐底辟不发育的缓坡,为致密油、页岩气等非常规油气资源富集区,且潜力巨大。北美白垩系的勘探对其他地区的勘探具有良好的指导意义。
