云南思茅—景谷地区有两类储集层：碎屑岩储集层和碳酸盐岩储集层，其中碎屑岩储集层要优于碳酸盐岩储集层。孔隙类型主要为次生溶孔，偶见剩余原生粒间孔。它们的储集性能基本上属低孔渗性储集层，强烈的压实作用、压溶作用、胶结作用、充填作用、碳酸盐化作用及重结晶作用是导致该区储集层孔渗性差的主要原因。但在有利的构造部位有可能找到孔渗性较好的区块。文中还论证了地表样品中识别埋藏古溶蚀的标志。 There are two types of reservoirs in Simao-Jinggu, Yunnan: clastic reservoir and carbonate reservoir, of which clastic reservoir is superior to carbonate reservoir. Pore ​​types are mainly secondary dissolved pores, occasionally remaining primary intergranular pores. Their reservoir properties are basically low porosity and permeability reservoirs. Strong compaction, pressure solution, cementation, filling, carbonatation and recrystallization result in porosity and permeability of the reservoir The main reason for poor sex. However, it is possible to find blocks of better porosity and permeability in favorable structural locations. The paper also demonstrates the identification of burial paleosol in surface samples.
