epidiagenesis meaning in Chinese
表生成岩作用
后生成岩作用
Examples
- Chang - 2 oil - bearing beds of the yanchang formation experienced three diagenetic stages of early diagenesis , late diagenesis and epidiagenesis
研究区长2油层组经历了早期成岩阶段、晚期成岩阶段和表生成岩阶段三个成岩阶段。 - The acidic liquid related to decomposition of organic mater during hydrocarbon enrichment in the late diagenesis , and m eteoric - waters during epidiagenesis , had resulted in dissolution of detrital feldspars and carbonate cements , which contributed a better retention of reservoir quality for the sandstones
溶蚀作用是砂岩物性改善的主要原因，尤其是晚期成岩阶段，在富含有机酸和无机酸酸性孔隙流体的作用下形成一定量的次生溶蚀孔，使储层砂岩物性得到一定改善；在表生成岩阶段，由于大气降水的介入，储层物性再次得以改善。
