【Abstract】 In the late Permian coal-forming period, the basin of seam gas was developed in east Yunnan and west guizhou, which are the important areas of seam gas resources in South China. In this paper, we outline the classification and evaluation of the basin of seam gas, put forward the concept of seam gas system and study the emphtic basin. The zonation of seam gas area and the concept of geological risk analysis of seam gas are put forward. The seam gas resources prognosis and exploration target selection in the emphatic area and zone are carried out. The emphatic exploration-exploitation experiment area of seam gas and the evaluation of the exploration target of seam gas in east Yunnan and west Guizhow are put forward.更多还原
