| 1. | Diagenesis not only can change mineral composition , fabric component , and texture , etc . , but more important it can change the reservoir capability greatly , that is , it can build up , or reduce , or enlarge original pores , and even form a series of diagenetic crack . those secondary pores and cracks are important to improve reservoir capability , especially for carbonate
成岩作用不仅使岩石或沉积物的矿物成分结构组分构造等发生程度不同的变化，更重要的是使原岩的储集性能发生很大的变化，即对原生孔隙或堵塞或残留或扩大，而且还可产生一系列的成岩孔缝次生孔缝，这些次生孔缝对岩石储集性的良化，尤其是对碳酸盐岩是至关重要的。 |
