摘　　要：本文在前人研究基础之上,对川东五百梯地区长兴组生物礁、滩储层岩性和物性特征进行了研究分析。通过镜下观察对研究区天东74井的钻井岩屑薄片进行了岩性和孔隙类型分析,并对岩芯进行了物性统计分析。研究结果显示:长兴组储层主要分布于溶孔细晶白云岩,储集空间主要为粒间溶孔、晶间溶孔等次生孔隙,长兴组二段储层孔隙度总体上优于长兴组三段。研究成果可指导和影响后期的油气采收和化工生产。Based on previous studies,this paper studies and analyzes the lithology and physical properties of reef and shoal reservoirs of Changxing Formation in Baibaiti area,eastern Sichuan.The lithology and pore types of the drilling cuttings from Well Tiandong 74 in the study area were analyzed by microscope observation,and the physical properties of the cores were statistically analyzed.The results show that the reservoir of Changxing Formation is mainly distributed in the solution-pore fine grain dolomite,and the reservoir space is mainly secondary pores such as intergranular solution-pore and intergranular solution-pore.The reservoir porosity of the second member of Changxing Formation is generally better than that of the third member of Changxing Formation.The research results can guide and influence the later oil and gas recovery and chemical production.
