摘要
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 reservoir in the study area. The types of the pore are mainly secondary solution pores and seldom primary remanent intergranular pores. The reservoir of the clastic rocks is more superer than the reservoir of the carbonate rocks. Their reservoir property belongs basically to the reservoir with low porosity and low permeability. The main causes resulting in this situation are intense compaction, pressure solution, cementation, filling, carbonatization and recrystallization, but it is possible that the district with better porosity and permeability is found in favorable tectonic position. In this paper, the authors expound and prove the indications distinguishing the buried old solution in the sample of the earth′s surface.
