摘要:
为了评价样品粒径对页岩孔径参数测定结果的影响,并探索适用于页岩孔径参数测定的粒径范围,以渝东南地区下寒武统牛蹄塘组3块不同TOC含量的页岩为研究对象,结合低压N2/CO2等温吸附实验及有机岩石学、激光拉曼光谱学、XRD测试等方法,讨论了样品破碎、筛分等前处理对高过成熟度页岩的矿物组成、比表面积及孔径分布等测定结果的影响。结果表明:研究区下寒武统牛蹄塘组页岩孔隙类型主要为有机质孔和黏土矿物粒间孔,有机质孔隙的发育具有非均一性;破碎筛分会对页岩的矿物组成产生无规律的分异作用;样品粒径小于0.425 mm(>40目)时,粒径降低会增大页岩的比表面积并显著影响介孔和宏孔的孔体积,但是当样品粒径大于2 mm(<10目)时,会显著增加低压N2等温吸附实验的时间;粒径大小对微孔孔体积的影响不明显。综合实验结果的稳定性、时效性及页岩的非均质性等因素,建议采用10~40目的样品来开展页岩的孔径参数分析测试实验。
