The Member Shuang 2 Reservoir is an important hydrocarbon exploration and development layer of the Y59 area in the Moliqing fault depression�� Based on the study of sedimentary facies��characteristics of reservoir petrology��physical properties and oil-bearing��it is revealed the characteristics of oil-bearing feature and the oilwater distribution law of the Y59 area�� The lithology of the oil reservoir is dominated by siltstone and fine sandstone and sandy conglomerate�� The oil bearing grade is fluorescence above�� The reservoir porosity cutoffs for 8%��the lower limit of permeability is 0. 1 × 10 �� 3μm2��and the oil saturation is greater than 50%�� The Rlld of oil reservoir is over 30 Ω·m��and the AC is between 230. 0 �� 260. 0 μs /m�� High productivity wells are mainly located in the upper middle-fan near the northwestern margin��while the productiion is poor in the lower middle-fan�� It has higher productivity in the fault terrace among the reverse faults of the northwestern margin than other regions��
