| 摘 要： | 在对大量薄片分析鉴定的基础上,结合区域构造运动、盆地埋藏史和有机质热演化史,对睡宝盆地古近系储层次生孔隙类型和成因机制进行了研究。分析认为碳酸盐等组分的溶蚀、构造运动以及这两者之间的匹配是次生孔隙形成的主导因素。晚渐新世构造挤压运动导致渐新统地层抬升暴露,酸性大气淡水在表生淋滤阶段溶解岩石颗粒之间方解石胶结物,形成次生溶孔。始新统储层虽然存在有机质热演化过程中产生的酸性流体的溶蚀作用,但是由于有机酸流动受阻,并未形成广泛的次生孔隙。

| Abstract: | Based on petrographic microscope examinations,regional tectonic evolution and basin burial history in Shwebo basin,Myanmar,type and mechanism of secondary pores of Paleogene reservoir is discussed.The major factors controlling development of secondary porosity included dissolution of acidic components(such as carbonate),tectonic activity and matching of them.The structural compression in late Oligocene caused the uplift of the Oligocene strata and explore,then the calcite cement between grains was dissolved... |
