中文摘要：
随着苏里格气田北部山，段、盒。段碎屑岩气藏的不断发现，其物源引起了人们的重视。为了查明苏里格气田北部山，段、盒8段的物源问题，应用数理统计的方法，结合碎屑组分特征、重矿物分布特征、岩屑类型、石英颗粒的阴极发光等特征．对苏里格气田北部地区山。段、盒。段的物源进行了系统的研究。结果表明：苏里格气田北部地区在山。段、盒。段沉积时期，受到北部和东北部2个物源方向的影响，物源区为盆地北缘的阿拉善-阴山古陆。物源与苏里格气田北部地区沉积体系的展布格局和储集砂体的物性具有密切的关系。
英文摘要：
Along with the discovery of clastic rock gas reservoir in Shan1 session and He8 session in the northern part of Sulig gas field, provenance issues have attracted common attention. Systematic research has been conducted with the application of mathematical statistics methods, combined with composition features, heavy minerals distribution features, clastic types and quartz gram. These results indicate that during the deposition of Shan1 and He8 session, the clastic sediments were frorn northern and northeastern basin, and the provenance can be traced from Alanshan-Yinshan ancient continent. The provenance and sediment system distribution pattern of the northern area of Sulig gas field are closely linked to physical properties of reservoir sandbody.
