Abstract

Abstract:

This paper deals with mudstone sampled from the first member of the Cretaceous Qingshankou Formation in the Songliao Basin. We qualitatively and quantitatively investigated characteristics of its micropores using scanning electron microscope (SEM), field-emission SEM (FE-SEM), gas adsorption and high-pressure mercury-injection methods. The results indicate that there are mainly five pore types in the mudstone, including matrix intercrystal, organic, dissolution, intergranular and intracrystal pores as well as micron to nano microfissures. Pores in the mudstone are mainly composed of micropores and meso-pores with pore volume generally ranging from 0.0018 to 0.0300mL/mg, specific surface area from 0.91m²/g to 31.02m²/g and porosity from 1.2% to 3.9%. It is believed that compositions and concentrations of various minerals in the mudstone determine, to a certain extent, development of micropores. For instance, the mudstone porosity increases with increasing content of organic matter(OM), illite or pyrite but decreases with increasing content of chlorite, quartz, calcite or anorthose. Moreover, the mudstone porosity has a poor correlation with content of kaolinite, indicating that abundance of kaolinite may not affects variations of mudstone porosity.

Key words: micropore, pore volume, specific surface area, porosity, mudstone, Qingshankou Formation, Songliao Basin

摘要：

以松辽盆地白垩系青山口组一段泥岩为研究对象，综合利用扫描电镜、场发射电镜、气体吸附法及高压压汞法对其内部微观孔隙进行了定性和定量研究。结果表明该套泥岩主要发育5种类型孔隙（基质晶间孔隙、粒间孔隙、有机质孔隙、晶内孔隙、溶蚀孔隙）以及微米-纳米级微裂缝。泥岩孔隙主要以微孔和介孔为主，孔容为0.0018～0.0300mL/mg，比表面积为0.91～31.02m²/g，孔隙度较低，为1.20%～3.87%。岩石的组成成分和含量在一定程度上控制了孔隙的发育和分布。孔隙度随有机质、伊利石及黄铁矿含量的增加而增大，随绿泥石以及石英、方解石、斜长石含量的增加而降低，而与高岭石含量相关性差，表明孔隙度的大小可能不受高岭石的影响。
