摘　　要：塔里木盆地巴麦地区寒武系埋深大,构造复杂,是近年来勘探的又一个重点和难点,在研究钻井岩芯等资料的基础上综合利用岩芯、薄片、扫描电镜、碳氧同位素、阴极发光、流体包裹体等测试手段,探讨和总结了巴麦地区寒武系储层普遍发育,肖尔布拉克组储层受控于不整合相关台内藻丘、(膏)云坪相控制,叠加了晚期断裂-深部热液溶蚀的改造,有利区带主要为巴楚北部、井10井区和玛扎塔格构造带。The Cambrian in Bamai area of Tarim Basin is deeply buried and complex in structure,which is another key and difficult point of exploration in recent years.Based on the study of drilling core and other data,I comprehensively use core,thin section,scanning electron microscope,carbon oxygen strontium isotope test and other means to discuss and summarize the general development of Cambrian reservoirs in Bamai area,The reservoir of the Xiaoerbulak formation is controlled by the unconformity related platform algal mound and(gypsum)cloud flat facies,superimposed with the transformation of late fault deep hydrothermal dissolution.The favorable zones are mainly northern Bachu,Batan 5 well area and mazatag structural belt.
