东河砂岩由溶蚀相、原生孔隙相、溶蚀-原生孔隙相和碳酸盐胶结相组成。
The Donghe sandstone is composed of denudation facies, primary pore facies, denudation-primary pore facies and carbonate cementation facies.
沉积相带和成岩作用是影响储层物性的主要因素，次生孔隙带的发育与溶蚀作用关系密切。
Sedimentary facies zone and diagenesis are major affecting factors for pore reservoir structure. The growth of secondary pore zone is closely related to dissolution.
不同的沉积微相其胶结类型不同，从而导致酸性水溶蚀次生孔隙所发育的程度迥异。
Generally, different sedimentary microfacies developed different types of cementation that controlled distribution of secondary pore dissolved by acid water solution.
