摘要
在前人作的大量研究基础上,通过铸体薄片、普通薄片、扫描电镜等资料的系统观察、分析,认为西山窑组的储层发育与成岩压实作用密不可分,主要表现在西山窑组砂岩主要以缝合线-线接触为主;研究表明,该区的成岩作用还包括胶结作用、溶蚀作用、交代作用;影响该区储层物性的因素中最重要的是散乱分布的自生高岭石。
Through comprehensive analysis of cast thin section,common thin section and scanning electron microscope(SEM),it was considered that the reservoir grouth in Xishanyao Formation was closely related with diagenesis and compaction.It is presented by concave-convex contact and suture contact,also the diagenesis includes the cementation,denudation and metasomasis;kaolinit distributed disorderly in the pore is the most important factor effecting the porosity and the permeability.
