摘　　要：为了指出塔里木盆地志留系地层岩性圈闭有利勘探区带,在志留系地震地质统层的基础上,选取骨干地震剖面进行地震层序划分,对沉积相特征进行了研究.结果表明志留系层序地层划分为4个层序和7个体系域;从陆棚沉积体系到滨岸及潮坪沉积体系,志留系总体为从下向上水体变浅.分析了志留系形成大型地层岩性油气藏具备的地质条件,通过研究指出塔中北坡存在发育大型地层岩性油气藏的地质条件.In this paper, Silurian has been subdivided into 4 sequences and 7 system tracts based on stratigraphic correlation of Silurian in Tarim Basin, and the characteristics of each sequence and system tract has been described in detail according to seismic data and well data. The exploration potential analysis shows that there exists the geological condition in which large stratigraphic oil-gas reservoir may develop in the north slope of Tazhong area.
