细粒沉积岩研究现状及发展趋势

Present Situation and Development Trend of Fine Sedimentary Rocks

细粒沉积岩在沉积学中是一个相对较薄弱的领域,其研究程度远远低于粗碎屑岩,但随着页岩气以及致密油等非常规油气的勘探开发,细粒沉积岩受到广泛的关注和研究。文章在结合国内外细粒沉积岩研究现状的基础上,重点阐述了国内细粒沉积岩在岩石定名、层序划分、存储特征及油气勘探现状等方面取得的成果,为今后的细粒沉积岩的研究和非常规油气的开发提供一定的理论依据。

Fine-grained sedimentary rock is a relatively weak field in sedimentology, and its research degree is far lower than that of coarse clastic rock. But with the exploration and development of unconventional oil and gas such as shale gas and tight oil, fine-grained sedimentary rock has received extensive attention and research. On the basis of the present research situation of fine-grained sedimentary rocks at home and abroad, this paper focuses on the achievements of the domestic fine grain sedimentary rocks in the aspects of rock naming, sequence division, storage characteristics and present situation of oil and gas exploration, etc., which provides some theoretical basis for future study of fine-grained sedimentary rocks and the development of unconventional oil and gas.
