摘　　要：本文总结归纳了２０多个含油气盆地粘土矿物的类型，讨论了８种较常见的、６种较少见的和３种极少见的粘土矿物的Ｘ射线衍射特征及其成分、形态和分布等方面的矿物学特征．he analysis of more than 20 thousands samples from more than 20 basins shows thatthere are only 17 types of clay minerals in China oil--bearing basins, including kaolinite,montmorillonite, beidellite, illite, tri.--chlorite, randomly interstratified illite/smectite, ordered interstratified illite/semctite, randomly interstratified tri.--chlorite/smectite, serpentine, pyrophyllite, saponite, di chlorite, randomly interstratified di' -chlorite/smectite,palygorskite, rectorite, corrensite and tosudite. The former & types are common, the middle 6 types are few and the last 3 types are very few. All of them have been described in detail in characteristics such as X-ray diffraction, shape, chemical composition and occurrence.
