随着石油勘探的发展,在岩石学领域中成岩作用的研究日趋深入,特别是长期处于困境的碎屑岩的成岩研究,自七十年代末以来更有明显的进展.本文从沉积学角度分析溶解作用产生的次生孔对砂岩成分和结构的影响.骨架颗粒的溶解产生次生孔,在一些砂岩中是普遍的.骨架颗粒的广泛溶解可能使人们错误地解释砂岩的原始成分和结构,导致错误地分析其物源及搬运和沉积方式.要避免这些问题必须认识由颗粒溶解产生的次生孔.正确区分沉积组分和成出组分,将有利于探区古地理再造.
With the development of oil exploration, the study of diagenesis in the field of petrology has been studied more and more. Especially, the diagenesis of the long-standing clastic rocks has been more obvious since the end of the seventies .In this paper, from the perspective of sedimentology Effect of dissolution secondary pores on sandstone composition and structure. The dissolution of framework particles produces secondary pores that are common in some sandstones. The extensive dissolution of framework particles may mislead people into interpreting the original composition and structure of the sandstone, Leading to the wrong analysis of the provenance and handling and deposition methods.To avoid these problems, it is necessary to recognize the secondary pores caused by the particle dissolution.The correct distinction between sedimentary components and composition, will help reconstruct the paleogeography of the exploration area.
