摘要
为进一步明确延安地区长7段陆相泥页岩孔隙结构差异,采用场发射扫描电镜、氮气吸附等测试方法,基于有机地球化学特征、矿物成分组成对泥页岩孔隙类型及其孔隙结构分布特征进行分析。同时,通过有机质丰度、有机质成熟度、黏土矿物含量等指标探讨影响泥页岩孔隙发育的主要因素。
In order to further clarify the pore structure differences of Chang 7 continental mud shale in Yan′an area,the pore types and pore structure distribution characteristics of shale are analyzed based on organic geochemical characteristics and mineral composition by field emission scanning electron microscopy and nitrogen adsorption test methods.At the same time,the main factors affecting the pore development of shale are discussed through organic matter abundance,organic matter maturity,clay mineral content and other indicators.
