| 摘 要： | 利用孢粉组合、特殊岩石类型和泥岩的原生颜色等恢复松辽盆地中生代古气候，发现在白垩纪时期发生了4次较长期的气候变迁，从登娄库组沉积开始大部分地层沉积时气候干热或较干热，可容空间大小、层序演化和体系域分布均受气候变化旋回控制，在此基础上划分了5个全气候层序，其中低水位体系域的盆底扇和斜坡扇最有利于油气富集。

| Abstract: | Utilizing sporopollen assemblage, special rock type and primary color of mudstone, we reconstructed Mesozoic paleoclimate in the Songliao basin and discovered that four long-term climate changes took place in Cretaceous. From Denglouku Formation, most strata were deposited in dry and hot climate. During that period, climate change cycles controlled the accommodation space size, evolution of stratigraphic sequences and distribution of system domains. Five climate sequences are divided on this basis, of which base fan and slope fan in the lowstand system tract are the most favorable for the oil and gas accumulation. |
