摘　　要：随着常规型油气藏的开发进入中后期，页岩气作为一种重要的非常规油气藏越来越受到广泛关注。甘肃走廊区武威盆地是祁连一阿拉善地区石炭系发育和保存较好的地区之一，其沉积环境以三角洲为主，其次为滨湖相、深湖相，有利于烃源岩的形成，且页岩分布广泛，厚度较大。该区石炭系页岩有机碳含量高，处于高成熟-过成熟阶段，有机质类型为Ⅲ型，具有较好的页岩气形成条件。With the development of conventional type reservoirs into the late, shale gas as an important unconventional petroleum reservoirs causes widely concern. Wuwei basin which locals in the eastern part of Gansu aisle area is a part of Qilian-Alashan area Carboniferous with better growth and preservation, delta facies is the major sedimentary environment, followed by the lakeside facies and deep lake facies, is favor of hydrocarbon source rocks formation, the shale widely distributed, and thickness. The shale contents high organic carbon, and is in the high mature - over mature stage, the organic matter is type Ⅲ, it has better conditions for shale gas formation.
