The differences in reservoiring conditions of natural gas and oil, as well as the multicycle developments and evolution histories of major gas bearing basins in China, and the geological environments characterized by relatively active tectonic movements in later period have resulted in the forming conditions of gas fields in China to be more complicated than those in many basins all over the world.

由于天然气与石油在成藏条件上的差异和中国主要含气盆地多旋回的发展演化历史、晚近时期构造运动比较活跃的地质环境，中国气田形成条件较世界上许多盆地复杂和成藏类型较多。总结中国大中型气田的成藏历程，可以新近纪、古近纪和中生代为界将气田的形成归为 4类：1超晚期生烃成藏型；2晚期生烃成藏型；3早期生烃聚集和晚期定型成藏型；4早期生烃成藏型。在这 4类中，以晚期和超晚期成藏和定型为主且分布最广、天然气前景最好、是中国天然气最主要富集领域。早期生烃成藏型在保存良好的盆地也有较好的前景。

Based on the background information on the part of the existing strategy adopted by the Beijing Gas Group, this paper conducts a detailed analysis of strategic issues of this group company by using such analytical tools as SWOT Matrix, Boston Matrix and Portor's Five Forces Model. The author discusses the status in quo of global gas market and domestic market, the internal environment of the group company, and the structure of gas industry. The major strategic problems of the group company are summarized on the basis of above-analysis, including the obsolete thoughts of decision makers, the weak management system of human resources, the deviation on building corporate culture, and the teetering on information processing.
