摘要
本文简要介绍了粘土岩较为重要的成岩作用:压实作用和脱水作用,并以其为基础阐述了粘土岩在含油气系统的基本要素和成藏作用中所扮演的角色,指出粘土岩在烃源岩、盖层、储层、圈闭的形成、油气的生成和运移中的研究意义。
Clayrock has an important meaning for its complex mineralogical component and particular diagenesis. In this paper, compaction and dehydration and the most important diagenesis of clayrock are introduced briefly. On the basis of these, the roles which clayrock plays in the basic factors and pool-forming role of petroleum system are demonstrated. The implications that clayrock acted as generating rock, overlie, reservoir and during trap-forming, oil and gas formation and migration are pointed out.
