epidiagenesis
解釋
表生成巖作用-
Chang - 2 oil - bearing beds of the yanchang formation experienced three diagenetic stages of early diagenesis, late diagenesis and epidiagenesis
研究區長2油層組經歷了早期成巖階段、晚期成巖階段和表生成巖階段三個成巖階段。 -
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
溶蝕作用是砂巖物性改善的主要原因，尤其是晚期成巖階段，在富含有機酸和無機酸酸性孔隙流體的作用下形成一定量的次生溶蝕孔，使儲層砂巖物性得到一定改善；在表生成巖階段，由於大氣降水的介入，儲層物性再次得以改善。
