沉积物的分选和压实作用影响渗透率和孔隙度。

Sediment sorting and compaction influence permeability and porosity.

沉积物分选越差或压实越紧，其孔隙度和渗透率就越低。

The more poorly sorted or the more tightly compacted a sediment is, the lower its porosity and permeability.

沉积作用控制了碎屑岩杂基、分选、磨圆等结构特征，进而控制了原生孔隙结构，为后期溶解作用的形成奠定了基础。

Sedimentation controlled the textures of clastic rocks such as matrix, sorting and rounding, and further affected the texture of primary pores, which served as basement for later dissolution.
