在石油生成、运移、储集以及钻井、采油工艺研究中都要碰到粘土矿物的问题,因此,对粘土矿物的研究,已成为国内外石油地质研究的重要课题之一。准确鉴别各种粘土矿物是粘土矿物研究的基础。目前鉴定粘土矿物最基本的手段是 X 射线衍射分析。应用 X 射线分析鉴定单一的矿物成分此较容易,但是沉积岩和土壤中往往是多种粘土矿物同时存在,在对泥岩和砂岩粘土矿物的分析中,经常遇到同一块岩样,既有高岭石又有绿泥石。如何鉴别高岭 Therefore, the study of clay minerals has become one of the important topics in the research of petroleum geology at home and abroad in the research of oil generation, migration, reservoir, drilling and oil recovery. Accurate identification of various clay minerals is the basis of clay mineral research. Currently the most basic means of identification of clay minerals is X-ray diffraction analysis. It is easier to identify a single mineral component using X-ray analysis, but often multiple clay minerals are present in sedimentary rocks and soils. In the analysis of mudstone and sandstone clay minerals, the same rock specimen is often encountered, Stone and chlorite. How to identify kaolinite
