摘要
总结分析中国陆相页岩油与北美海相页岩油的地质、开发特征差异,梳理了中国陆相页岩油开发评价方法与技术进展,指出了中国陆相页岩油开发存在的问题及发展方向。阐述了中国页岩油开发评价技术在有利岩相识别、储集性表征、可动性评价、可压性评价、产能评价及地质建模-数值模拟一体化“甜点”分析等方面的研究进展。指出中国陆相页岩油高效勘探和有效开发面临基础理论研究薄弱、勘探开发技术体系不完善、工程技术与国外差距大、开发成本高等多方面的难题。提出陆相页岩油开发发展方向:开展地质工程一体化综合研究,形成陆相页岩油差异化开发技术;加强大数据和人工智能应用,提高开发评价的精准性;攻关页岩油提高采收率技术,探索有效开发方式,提高开发效果和效益。
This paper analyzes the differences in geological and development characteristics between continental shale oil in China and marine shale oil in North America, reviews the evaluation methods and technological progress of the continental shale oil development in China, and points out the existing problems and development directions of the continental shale oil development. The research progress of development evaluation technologies such as favorable lithofacies identification, reservoir characterization, mobility evaluation,fracability evaluation, productivity evaluation and geological-mathematical modeling integration are introduced. The efficient exploration and development of continental shale oil in China are faced with many problems, such as weak basic theoretical research, imperfect exploration and development technology system, big gap in engineering technology between China and other countries, and high development cost. Three key research issues must be studied in the future:(1) forming differentiated development technologies of continental shale oil through geological and engineering integrated research;(2) strengthening the application of big data and artificial intelligence to improve the accuracy of development evaluation;(3) tackling enhanced shale oil recovery technology and research effective development method, so as to improve the development effect and benefit.
