摘　　要：总结四川盆地天然气勘探历程及启示,分析其持续发现大型气田的有利因素,以期推动天然气勘探取得更大战略突破。在梳理四川盆地天然气、页岩气等大型气田勘探成效的基础上,分别从地质条件、资源基础、理论创新和技术进步四方面剖析了四川盆地持续发现大气田的有利条件。研究认为,在大气田战略发现过程中,成藏地质要素良好时空配置是大气田形成的重要前提;天然气资源种类全、分布广、潜力大是大气田发现的物质基础;不断创新的勘探理论指导实践是大气田发现的关键核心;技术进步与装备提升是大气田发现的重要支撑。四川盆地天然气资源丰富,具有探明6个万亿立方米特大型气区潜力,有望建成天然气(页岩气)千亿立方米级产能基地,建议继续加强油气地质理论研究,不断提升勘探开发技术装备,继续加大勘探开发力度,推动四川盆地的大气田勘探迈上新台阶。This paper summarizes the history of natural gas exploration in Sichuan Basin and analyzes the favorable factors for the continuous discovery of large gas fields in order to promote the strategic breakthrough of natural gas exploration.On the basis of sorting out the exploration results of natural gas,shale gas and other large gas fields in the Sichuan Basin,the favorable conditions for the continuous discovery of large gas fields in the Sichuan Basin are analyzed from four aspects:geological conditions,resource base,theoretical innovation and technological progress.It is considered that in the process of strategic discovery of large gas fields,a good spatial and temporal allocation of geological factors is an important prerequisite for the formation of large gas fields.Multiple types,wide distribution and great potential of natural gas resources are the material basis for the discovery of large gas fields.Use of innovative exploration theory to guide practice is the key to the discovery of large gas fields.Technological progress and equipment upgrading are important support for the discovery of large gas fields.Sichuan Basin is rich in natural gas resources,with the potential of 6 trillion cubic meters of super-large gas areas proved,and is expected to build a production base of 100 billion cubic meters of natural gas(shale gas).The analysis and summary lead to the recognition that,for the promotion of large gas field exploration in Sichuan Basin,it is necessary to strengthen the theoretical research of oil and gas geology,constantly improve exploration and development technology and equipment,and continue to increase exploration and development efforts.
