| 摘 要： | 库车坳陷白垩系巴什基奇克组砂岩储层内石英颗粒溶蚀作用较发育,溶蚀主要发育在颗粒内部或颗粒边缘.储层内石英颗粒的溶蚀效应呈现出明显的平面非均质性特征,溶蚀增孔量高值区的储层内不仅在胶结物上富集方沸石胶结物,在粘土矿物组合上也表现出富伊利石贫高岭石的特征.通过层间泥岩硼元素含量的测定,对研究层段同沉积地层水体盐度进行恢复,...

| Abstract: | Taking the Cretaceous Bashijiqike Formation in the Kuqa depression as an example,this study suggests that the dissolution of quartz grain in sandstone reservoirs is extensive,with dissolution occurring mainly in the interior and around the rim of quartz grains.Reservoir in the areas with high value of quartz dissolution pore is not only enriched in analcime cement but characterized with rich illite and poor kaolinite also.Salinity of syndepositional formation water in the studied section was reconstructed u... |
