Abstract: In order to further expand the exploration degree of tight gas in the eastern margin of Ordos Basin, based on the analysis of regional source rock,reservoir,caprock and hydrocarbon transport system,combined with fluid inclusion test,the tight gas accumulation conditions of Carboniferous-Permian in Shenfu block were studied. The results show that the main coal seams are thick and stable,and the better hydrocarbon generation intensity constitutes the basic conditions for accumulation. The reservoir is characterized by low porosity and low permeability, with residual intergranular pores and intragranular dissolved pores as the main reservoir space. The mudstone widely developed in Carboniferous-Permian has good sealing capacity. The homogenization temperature of fluid inclusions indicates the first stage of continuous reservoir formation,and three reservoir-cap assemblage models,namely,within source,near source and far source,can be divided. The difference of source reser-voir configuration in different layers controls the formation of different accumulation models. The related achievements and understanding further expand the prospect of petroleum exploration and development in Ordos Basin,and provide a theoretical basis for oil and gas exploration in the study area and similar tight gas fields.

Key words: tight sandstone reservoir, accumulation law, controlling factor, Upper Paleozoic, northeastern margin of Ordos Basin
