【摘要】 鄂尔多斯盆地延长组7段(长7段)蕴藏着丰富的页岩油资源,其中长7段砂岩夹层型页岩油的勘探开发已经取得了实质性突破,泥页岩型页岩油的勘探开发潜力巨大,是长庆油田未来重要的油气接替资源,但其相关地质基础性研究相对薄弱。在对鄂尔多斯盆地长7段泥页岩特征及页岩油勘探意义、形成古环境恢复、凝灰岩的有机质富集效应和生烃催化作用等相关问题进行阐述与思考的基础上,认为应持续重视纯泥页岩型页岩油等相关地质基础研究,现代湖泊半深湖-深湖相沉积考察研究可为泥页岩形成古环境恢复以及形成机理等研究提供可借鉴的思路和方法;重视凝灰岩对烃源岩生烃催化方面的研究,并开展一系列的凝灰岩中富集元素催化作用的热模拟实验研究,为长7段纯泥页岩型页岩油的勘探开发提供重要的地质基础参数。更多还原

【Abstract】 Rich shale oil resources are contained in the 7^thMember of the Yanchang Formation（Chang 7 Member）in the Ordos Basin. The exploration and development of the Chang 7 Member sandstone interbedded shale oil has made substantial breakthroughs. The exploration and development potential of the shale oil,an important oil and gas replacement for Changqing Oilfield in the future,is huge. But its related geological basic research is relatively weak. This paper gives elaborations and thinkings on basic science issues,including:Characteristics of mud shale,the significance of shale oil exploration,the restoration of the formation of paleo-environment,the organic matter enrichment effect of tuff and the catalysis of hydrocarbon generation,etc. It is believed that continuous attention should be paid to related geological basic research,such as pure mud shale-type shale oil,and modern lacustrine semi-deep lake-deep lake facies sedimentation investigations can provide valuable ideas and methods for the study of mud shale formation,paleoenvironment restoration and formation mechanism. Meanwhile,we should pay close attention to the research on the catalysis of tuff on the hydrocarbon generation of source rocks and carry out a series of thermal simulation experiments on the catalysis of enriched elements in the tuff,providing important basic geological parameters for the exploration and development of Chang 7 Member pure mud shale-type shale oil.更多还原
