摘要
利用储层砂岩薄片鉴定与电镜扫描、压汞测定、定量统计等方法,对榆林气田长北区块盒8段的储层岩石学特征、储层物性特征、储集特征以及影响储层的因素进行了系统的研究。结果表明:本区盒8段属低孔低渗储层;储层岩性以岩屑石英砂岩、岩屑砂岩为主;研究区储层孔隙空间主要有残余粒间孔,次生溶孔,高岭石晶间孔和微裂隙。通过对该区储层特征的研究,可为下一步勘探开发提供地质依据。
Through the statistical analysis of sandstone thin section identification, electron microscope scanning, mercury injection curves, physical property and so on, studied the petrology characteristics, reservoir physical property, reservoir characteristics and influence factors of reservoir of He 8 reservoir in Changbei area, Yulin gasfield. The results show that the He 8 reservoir belongs to low porosity, low permeability. The He 8 reservoir rock types are mainly lithic quartz sandstone and lithic sandstone. Reservoir pore types are mainly the residual intergranular pore, secondary solution pores, kaolinite intercrystal pore and micro crack. The study of reservoir characteristics in the area can provide geological basis for fur-ther exploration and development.
