虽然晚成岩期自形或半自形石英胶结损失了部分粒间孔隙，但仍能形成孔隙度相对较高的储层。
Although automorphic or partial automorphic quartz cementation losses some intergranular pores in late diagenesis, the reservoir with relatively high porosity still can be formed.
这种后期的方解石胶结物主要充填剩余粒间孔隙，使储层的有效孔隙度大大降低。
The remnant intergranular pores were filled with this kind of late calcite cement, which leads to a great decrease of the effective porosity.
原生孔隙度以砂岩粒问孔隙度和某些石灰石的晶体粒间和鲕状孔隙度为代表。
Original porosity is typified by the intergranular porosity of sandstones and the intercrystalline and oolitic porosity of some limestones.
