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.
储层以原生剩余粒间孔隙为主,长石及早期碳酸盐胶结物的溶解是形成次生孔隙的主要原因。
The main pore type of the reservoir is primary remained intergranular pore, the dissolution of the feldspar and early carbonate cement results in the secondary pore.
自生高岭石胶结可保留粒间微孔隙,对渗透性影响较小,甚至可增强渗透性。
The cementation of authigenic kaolinite may preserve the tiny intergranular pore-space, and slightly influence the porosity, and even increase the permeability.
