Using the theory of gray system to study well logging, drilling coring, oil testing and related geological data, the parameters of lithology, physical properties, oil content are refined by matching, fitting and extracting the parameters by statistical analysis of eigenvalues and their accuracy and resolution Sexual and capping qualities. Based on the data of Tazhongliu, Devonian and Carboniferous Donghe sandstones, the detailed evaluation parameters, standards and weight coefficients of the gray system reservoir-cap combination are given, and the treatment methods and application examples of the fine evaluation of reservoir and cap layer are analyzed . The detailed evaluation and comprehensive explanation of the reservoirs and caprocks in the Tarim, Liaohe, North China, Erlian and Yanchang oilfields have been calculated, and the parameters of reservoir and caprock of the main purpose intervals, drainage pressure or breakthrough pressure have been calculated. The lithology, Oiliness and cover quality categories, grades, collocations of reservoirs and caprocks and interpretation of oil, gas and water layers, which provide the corresponding geological basis for further exploration and development of different types of oil and gas reservoirs.
