Abstract: Based on the anaysis of genesis and geological implication of illite coatings of Yanchang Formation, the occurrence, chemical composition, distribution characteristics of the illite coatings and its relationship with chlorite coatings were studied by thin section analysis, SEM observation and EDX. The results show that:(1) The illite coatings of Triassic Yanchang Formation in Ordos Basin that are of the same occurrence of authigenic smectite coatings, were formed by the mesogenetic replacement of authigenic smectite coatings.(2) The authigenic smecite and chlorite coatings grew vertically on detrital grain surfaces at the same time owing to the dissolution of volcanic materials whose composition controlled the type of coatings. The illitization of smectite coatings were often accompanied by the dissolution of K-feldspar.(3) The curved flake illite is much larger and thinner than chlorite, and the intercrystalline matrix porosity of illite coatings is much higher than that of chlorite coatings, resulting in that only chlorite and illite can be observed in the inner layer and outer layer of illite coatings in thin sections respectively, while only illite can be easily seen under the scanning electron microscope. Although illite coating reduces reservoir permeability, it is conducive to the preservation of pores and water wettability of sandstone, which is of great significance for oil and gas production. The research results have reference significance for the prediction and development of high-quality reservoirs of Triassic Yanchang Formation in Ordos Basin.

Key words: illite coating, chlorite coating, smectite illitization, Yanchang Formation, Triassic, Ordos Basin
