Controls on the composition and distribution of the clay minerals from the Jurassic sandstone reservoirs in the Turpan-Hami Basin, Xinjiang

摘要: 在大量分析数据基础上,总结了吐哈盆地侏罗系砂岩储层中粘土矿物组成及其在纵横向上的分布特征,重点对吐哈盆地侏罗系砂岩储层中粘土矿物组成和分布的主控因素进行了分析,笔者认为吐哈盆地成岩过程中砂岩孔隙介质条件、不同沉积环境砂体渗滤条件的差异、盆地的大地构造背景和构造发育史以及盆地演化过程中的古气候变化等是影响盆地砂岩粘土矿物组成和分布的主控因素。由此可以为寻找有利储层和设计酸化采油方案提供重要的依据。

Abstract: The present paper deals with the controls on the composition and distribution of the clay minerals from the Jurassic sandstone reservoirs in the Turpan-Hami Basin, Xinjiang The controlling factors include medium conditions for sandstone porosity during diagenesis, infiltration of sandstone bodies formed in distinct sedimentary environments, tectonic settings, and palaeoclimates in the basins. The results in this study may be the important basis for the exploration of better sandstone reservoirs and establishment of the design schemes for acidulating oil extraction.
