摘要(Abstract)：

为探讨粘土矿物转化与储层孔隙演化的规律性,预测次生孔隙发育带及油层可能的分布,以苏北盆地台兴油田阜三段储层为例,基于岩心铸体薄片、普通薄片、X-衍射、压汞的测试数据及扫描电镜微观图像观察,分析了全岩中粘土矿物总含量对储层面孔率的定量影响。研究了粘土矿物类型与储层面孔率及孔隙结构的关系。总结了粘土矿物成分与孔隙演化的对应关系。最后详述了粘土矿物转化与孔隙演化及油层分布的规律。研究表明渐变带与原生孔隙发育带一致;粘土矿物第一迅速转化带与次生孔隙发育带一致;粘土矿物第二迅速转化带对应于次生孔隙减少带。粘土矿物第一迅速转化带为次生孔隙和油层的主要分布带。
In order to study rules of clay mineral transformation and reservoir pores evolution and predict potential distribution of secondary pores development belt and reservoirs,this paper takes Fu III Member of Taixing Oil Field in Subei Basin as an example to analyze effect of total content of clay mineral on reservoir surface pore percentage in whole rock on the basis of core cast slice,ordinary slice,X-diffraction,mercury penetration test data and micro-observation of scanning electric microscope.The result shows that gradation zone develops similarly to primary pore zone,first quick transformation zone of clay mineral is similar with secondary pores development zone,and second quick transformation zone of clay mineral corresponds to secondary pores reducing zone.First quick transformation zone of clay mineral is the main distribution zone of secondary pores and reservoirs.
