摘　　要：塔中地区Ⅰ号断裂带良里塔格组礁滩复合体为塔里木盆地油气主要储层,通过对塔中Ⅰ号构造带西北部的顺6井奥陶系良里塔格组碳酸盐岩详细岩心观察和室内研究认为,顺6井区良里塔格组沉积微相主要为砂屑滩、鲕粒滩、生屑滩、灰泥丘,滩相储集体主要发育于高位体系域中,海平面上升下降变化控制着滩的沉积微相类型和垂向叠置关系。储集空间类型包括孔隙型、裂缝型和裂缝-孔隙型,主要储集空间以裂缝-孔隙型为主。砂砾屑滩和鲕粒滩、生屑滩是油气勘探的重要目标。The reef-bank complexes of Lianglitage Formation are the important reservoirs in No.1 Structure Belt of central Tarim Basin.Based on the integrated study of core,drilling and logging data of Lianglitage Formation in northwestern No.1 Structure Belt of central Tarim,it is considered that the main sedimentary facies of Lianglitaga Formation in Well Shun 6 are calcirudytic,bioclastic,oolitic banks and mudstone mound.The bank reservoir mainly develops in highstand system tract and the change of sea level controls the types of bank facies and vertical relationship.According to the analysis of core samples,the reservoir spaces of carbonate reservoir are divided into three types： pore type,fissure type and fissure-pore type.The fissure-pore type is the main type.The calcirudytic,bioclastic and oolitic banks are the important targets for petroleum exploration in this area.
