中文摘要：
大牛地气田盒2、3段的成岩作用主要包括压实作用、胶结作用、交代作用和溶蚀作用。该区主要孔隙类型以粒间和粒内溶蚀孔隙和晶间微孔为主，原生孔隙基本消失。据统计，该区储层属于低孔、低渗型储层。高岭石的晶间微孔对储层孔隙的贡献有重要作用，而方解石对储层影响包括破坏和建设两个方面。次生加大石英、绿泥石、伊利石则对储层的孔渗有明显的破坏作用。
英文摘要：
The diagenesis of Member He2 and Member He3 in Daniudi gas filed includes compaction, cementation, dissolution and denudation. The main pore types of the reservoir in this area are dissolution pores between grains and in grains and intergranular micropore, and primary pores almost disappear. The reservoir has low permeability and low porosity. The intergranular micropores of kaolinite greatly contribute to reservoir pores, while the calcite influences the reservoir both from damage and construction. Overgrowth quartz, chlorite and Illite obviously reduce the permeability and porosity of the reservoir.
