摘要
页岩气作为一种开发潜力巨大的非常规清洁能源在勘探开发上已取得较大进展,但对页岩气的成藏机理、富集条件、挑战与前景方面还有待进行深入研究。在调研大量国内外研究成果的基础上,结合多年工作经验,分析了目前国内外页岩气的研究现状及页岩气储层的特殊性,探讨了页岩气的成藏机理,从地质条件和外部因素分析页岩气的富集主控因素。研究了四川盆地页岩气的地质特征以及页岩气富集规律,指出四川盆地页岩气藏分布的有利区域和勘探开发方向。最后,总结了我国页岩气勘探开发存在的问题和发展前景。
As a kind of unconventional and clean energy with great exploitation potential, shale gas has made significant progress in exploration and development. However, its reservoir-forming mechanism, accumulation conditions, challenges, and prospects remain to be further studied. Based on large amounts of achievements, we analyzed the latest progress of shale gas and the particularity of shalegas reservoirs at home and abroad, discussed the reservoir-forming mechanism, and found out the main factors affecting its accumulation from aspects of geological conditions and external causes. Furthermore, we carried out certain study on shale gas in Sichuan Basin in terms of geological characteristics and accumulation law, and pointed out some favorable belts, and exploration and development targets. Finally, we summarized many existing problems, and proposed some shale-gas development prospects.
