摘　　要：在对建南地区井下岩心详细研究的基础上,结合测井、地震等资料和前人的研究成果,对建南地区二叠统长兴组沉积体系进行了分析,并研究其沉积相特征,确定其沉积相模式。研究发现,建南地区二叠统长兴组沉积相划分为碳酸盐缓坡沉积体系及碳酸盐台地沉积体系,其沉积相的发育和分布特征随着海平面升降变化而发生改变。Based on detailed studies of borehole core in Jiannan Area,combined with data of well logging and seism and previous research achievements,sedimentary facies in study area are analyzed.The Permian Changxing Formation is identified as carbonate ramp sedimentary system and carbonate platform sedimentary system,the preliminary sedimentary facies model of this area are summarized.The rise and fall of sea level is the main factor to control the development and distribution of sedimentary facies.
