3 . the correlation of isotopic constitution and the relations between diagenesis and co2 indicate that co2 mainly derived from tertiary ca - mud rocks . the carbonate cements in reservoirs under the affection of hot fluid may form co2 , but the yield of co2 is low
基于碳酸盐矿物及本区浅层co _ 2的同位素组成对比分析，并结合浅部储层成岩作用与co _ 2的相互关系，认为co _ 2可能来自第三系钙质泥岩。
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。
