我想说,有shale gas 这个概念,还有shale oil这个概念。 还有个观念纠正一下: 有气必有油,有油未必有气。" U9 f. [# O9 O s
第一:从烃源岩的角度来说,通常情况下,在页岩的热演化过程中,先是生成石油,然后裂解成气。如果一个地区有气的话,说明历史过程中,有石油生成,并且被排到储层中储层起来。如果说页岩的演化程度不是很高,那么只能生成油,而不会有气(不排除,低成熟阶段生物气的可能性,但是通常不足以工业经济开采) ; @$ I7 n H" {: B2 k2 z& Z 第二:从封盖层的角度来说,能够封闭气体的盖层,基本上一定能封闭石油,但是能作为石油的盖层不一定能封闭气体1 B3 ]- l7 f% I. W5 J
最后,通常,无论实在砂岩储层是碳酸盐岩储层,都是油气伴生。 shale gas或者 shale oil 只不过是页岩中生成的烃类没有及时排到有效储层,而储层在页岩中罢了0 g& @" j5 ?% G2 f' R
