摘　　要：近5年来,中国页岩气勘探开发实现了跨越式发展,成为继美国、加拿大之后,第三个实现页岩气工业化生产的国家,截至2015年底,页岩气累计产量突破了60×10~8 m^3。基于近期中国页岩气勘探开发快速发展的主要成果,通过全面回顾勘探开发新突破和深入分析未来发展前景,进而指出中国的页岩气勘探开发整体尚处在发展初期,四川盆地海相页岩气是近期勘探开发的主要对象,海陆过渡相与陆相页岩气的突破和工业化生产是实现中国页岩气规模化发展的重要环节;低产—中等产量井是中国页岩气的生产常态,发展勘探开发关键技术非常重要;严格控制单井投资和大幅降低成本成为提升页岩气勘探开发效益的重要手段。为此,建议:①持续加强理论技术攻关,积极开展页岩气"甜点区"评价勘探,逐渐夯实发展基础;②高度重视勘探开发前期评价,突出有效页岩气资源的落实,把控好评价钻探与产能建设的节奏;③突出页岩气储层精细描述和评价,提升整体开发水平;④加大勘探开发技术攻关力度,突出技术的简化和实用性,有效降低成本;⑤全面总结页岩气勘探开发快速发展经验,突出关键指标论证及评价,加强新区、新领域及新层系突破和接替。In the past five years, shale gas exploration and development has grown in a leaping-forward way in China. Following USA and Canada, China is now the third country where industrial shale gas production is realized, with the cumulative production exceeding 60×10^8 m^3 untill the end of 2015. In this paper, the main achievements of shale gas exploration and development in China in recent years were reviewed and the future development prospect was analyzed. It is pointed out that shale gas exploration and development in China is, on the whole, still at its early stage. Especially, marine shale gas in the Sichuan Basin has dominated the recent exploration and development. For the realization of shale gas scale development in China, one key point lies in the breakthrough and industrial production of transitional facies and continental facies shale gas. Low-moderate yield of shale gas wells is the normal in China, so it is crucial to develop key exploration and development technologies. Especially, strictly controlling single well investment and significantly reducing cost are the important means to increase shale gas exploration and development benefits. And finally, suggestions were proposed in five aspects. First, continuously strengthen theoretical and technical researches, actively carry out appraisal on shale gas ＂sweet spots＂, and gradually accumulate development basis. Second, stress on primary evaluation of exploration and development, highlight the effective implementation of shale gas resources, and control the rhythm of appraisal drilling and productivity construction. Third, highlight fine description and evaluation of shale gas reservoirs and increase the overall development level. Fourth, intensify the research on exploration and development technologies in order to stand out simple and practical technologies with low costs. And fifth, summarize the experiences in fast growth of shale gas exploration and development, highlight the demonstration and evaluation of key indicators, and try to achieve mo
