摘　　要：南堡凹陷下第三系砂岩储层是冀东油田的主力储层，发育多种孔隙类型但以次生孔隙为主，物牲变化复杂。综合运用沉积、成岩和油田水分析资料进行分析，认为物源和沉积相控制了储层的岩姓和原始物性，是其后一切变化的基础；机械压实作用是孔隙损失的主要原因，胶结作用次之；溶蚀作用是形成次生孔隙的主要成岩后生作用。Paleogene Reservoir in Nanpu sag, Bobal Bay basin is a main producinginterval. It develops many types of pores which are mainly secondary pores and haschangeable properties. Combining the evidences of sedimentology, diagenesis and oilfieldwater. it is concludes that the sedimentary process controls the lithology and primaryporosity. The porosity reduction is mainly caused by mechanical compaction, and thecementation is secondary factor. The dissolution, especially that of aluminosilicates is themain mechanics developing secondary porosity.
