late diagenesis meaning in Chinese
晚期成岩作用
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 diagenesis of the ed3 and es , sandstone has been evoluted to late diagenesis a and b stage , with mainly primary pores and secondary solved pores
油气储层的储集空间以原生孔隙、次生溶解孔隙为主，主要为中孔中渗储层。 - At the late diagenesis phase , the dissolution of frame grains , especially the dissolution of felspar and laumontite , is the key to form secondary porosity
朵状砂体的大小直接控制油藏的范围及规模，靖安地区的主要油藏多沿不同的朵状体成排分布。 - 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。
