| 摘 要： | 通过岩心观察、薄片鉴定、扫描电镜分析、X-射线衍射分析等手段,对鄯勒地区西山窑组碎屑岩储层的成岩作用进行了研究。西山窑组成岩阶段可分为早成岩B期和中成岩A期,中成岩A期又分为中成岩A1亚期和A2亚期,识别出压实作用、胶结作用、交代作用和溶解作用等4种成岩作用;强烈的压实作用和胶结作用是造成储层原生孔隙减少的主要原因,溶解作用形成的次生溶孔则有效地改善了储层的物性。综合储层沉积、成岩作用,可将西山窑组碎屑岩储层划分为3种类型,其中,Ⅰ类储层为低孔特低渗型,Ⅱ类储层和Ⅲ类储层为特低孔特低渗型。

| Abstract: | Here we studied the diagenesis characteristics and pore evolution of clastic reservoirs in the Xishanyao Formation of Shanle area by methods of core observation,slices arbitration,scanning electron microscopy and X-diffraction analysis.The diagenetic phases of the Xishanyao Formation included early diagenetic B stage and middle diagenetic A stage which was divided into A1 stage and A2 stage.The diagenesis can be divided into four types,including compaction,cementation,replacement and solution.The intense co... |
