被压力从岩石孔隙空间之中挤出的水以及夹带在水中的油雾雾珠和气泡会迁移到具有较低压力的高带中去。

The water squeezed out of the pore space, along with the drops of oil and GAS, moves toward high zones with lower pressure.

因此，深入研究砂岩成岩作用是分析孔隙水演化过程中离子迁移的重要环节。

Thus, studying sandstone diagenesis is an important link for analysis of ion migration in the evolution of pore-water.

孔隙的改善程度与控制矿物溶解后离子迁移能力的原始岩石物性等因素紧密相关。

The improvement of porosity was closely related to the physical properties of original reservoir.
