This porespace is known as porosity and is expressed as a percentage of the total rock volume.
这个孔隙空间被称为孔隙度,用岩石总体积的百分比表示。

The porosity increasing is primarily due to the resolution of carbonate so that a large amount of the secondary porespace is resulted.
而碳酸盐的溶解作用形成了大量次生孔隙空间,增加了砂岩的孔隙度。

In the original conditions, reservoir rocks and fluids inside the porespace in the pressure equilibrium, once the oil drilling, this balance was destroyed.
