【Abstract】 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.更多还原
