摘　　要：受限于技术经验不足、投资成本过高、地质条件复杂等因素,现阶段我国页岩气进展步伐有所放缓,诸多因素影响着人们对我国页岩气发展前景的正确认识。页岩气作为非常规资源继续促进着美国"能源独立",2014年产量占全美的48.2%;而煤成气作为我国重要的常规天然气资源,在天然气工业依然占据举足轻重的地位,到2013年底产量占全国的67.31%。通过系统分析两者发展历程、阶段特征和重要意义,可知:美国页岩气和我国煤成气的发展历程都是经历了漫长的前期理论研究和论证周期,稳重求进逐步打开了勘探局面,其年产量和探明储量的递增速率都是先慢后快,通过技术或勘探突破进入高速发展阶段;现今我国页岩气还处于勘探开发的初级阶段,与国外差距较大,需技术创新降低单井投资,深化地质理论认识,协调水资源利用以及企地关系等。Limited by technology experience insufficiency,the high cost of investment,complicated geological conditions,development pace of shale gas slowed down at the present stage in China,and many situations affect people to understand shale gas development prospects in China correctly.As unconventional resources,shale gas promoted the＂energy independence＂in United States,and it accounted for 48.2% of the national＇s production in 2014.As important conventional natural gas resources in China,the coal-derived gas still occupy the important position in the natural gas industry,its production had accounted for 67.31% by the end of 2013.Through systematic analysis of development history,phase characteristics and its significance,it is concluded that,both resources experienced a long period of preliminary theoretical research and demonstration,steady and gradually opening of the exploration situation.The increment speed of its production and reserves is slow at first and accelerated later and through technical or exploration breakthrough into the high speed development stage.Nowadays shale gas in China is still in the primary stage of exploration and development.The gap with foreign countries is also very big,and it needs technical innovation to reduce single-well investment,deepen the geological theory knowledge,and coordinating the relationship with nature and society,etc.
