摘　　要：储层孔隙发育情况是石油地质工作者最为关注的问题之一。文章以岩石薄片观察为依据，结合地表剖面观察、物性分析、有机质成熟史等资料，阐述了川东北部地区上三叠统香溪群砂岩储层的成岩作用与孔隙演化的关系。The development of the pores of a reservoir is one of the most important things concerned by the petroleum geologists.Based on the synthetic data of thin-section analysis,outcropobservation, petrophysical analysis, and the maturation history of organic matter,this paper expounds the relationship between the evolution of porosity and the diagenesis of the sandstonereservoir from the Upper Triassic Xiangxi Group in the north part of Eastern Sichuan.
