摘要
大气水-砂岩的相互作用是盆地流体研究的重要内容。大气水-砂岩的相互作用主要表现在两个方面。一方面,大气水在多孔介质中的流动导致碎屑矿物和成岩矿物的淋滤和再沉淀;另一方面,大气水的成分将缓慢地被“岩石”所改变。长石溶解与高岭石沉淀、稳定同位素和特征自生矿物是判断大气水-砂岩相互作用的主要标志。砂岩遭受大气水成岩作用与否和期次,取决于盆地的构造演化和砂岩在盆地中所处的位置。大气水-砂岩相互作用的研究对于在中国东部及东北亚中新生代含油气盆地中,寻找优质储层和油气伴生资源具有重要的指导意义。
The interaction of meteoric water-sandstone is an important part of the research of the basin fluid. The interaction of meteoric water-sandstone has two aspects.On the one hand,the flow of the meteoric water in the multiporous media leads to the infiltration and reprecipitation of the detrital mineral and diagenetic mineral;On the other hand,the component of the meteoric water will be changed by “rock”. The dissolution of feldspar and precipitation of gaolinite,stable isotope and distinct authigenic mineral are important remarks to recognise the interaction of the meteoric water-sandstone. Whether sandstone has the diagenesis of the meteoric water or not and episodes lie in the tectonic evolution of the basin and the position where sandstone is in the basin. That we research the interaction of the meteoric water-sandstone in the petroleum-bearing basin of Mesozoic-Cenozoic of the East China has a signifisance for finding the excellent reservoir and the associated resource of petroleum.
