摘　　要：源岩供烃、油气储集、运移路径以及保存条件是松北探区扶余油层油气成藏的主要控制因素。以此为基础，选取源岩平均厚度、有机碳质量分数、有机质成熟度、氯仿沥青“A”、有机质类型、油源区距探区距离、沉积相类型、储层平均厚度、盖层平均厚度和地层水矿化度10个指标作为松北探区扶余油层油气成藏综合评价参数，构建油气成藏模糊综合评价矩阵，引用层次分析法确定各参数的权重系数。通过计算松北探区13个区块扶余油层油气成藏条件综合评价值，可知松北探区扶余油层哈尔滨东区块油气成藏最有利，其次为宾县和木兰区块。The hydrocarbon supplied from the source rocks, petroleum accumulation, migration paths and conser- vation conditions are the main controlling factors on the petroleum reservoir formation in Fuyu oil layers of Songbei exploratory area. On the basis of the above, the following ten indexes are chosen for the comprehensive evaluating parameters of hydrocarbon reservoir formation in Fuyu oil layers： the average thickness of the source rocks, the mass fraction of the organic carbon, the maturity of organic matter, chloroform bitumen ＂A＂, the types of organic matter, the distance from the source region to the exploratory area, the kinds of the sedimentary facies, the average thicknesses of the reservoir and cap rock and water salinity. Thus the fuzzy combined evaluating matrix of hydrocar- bon reservoir formation is established, and furthermore the hierarchy analysis is introduced to determine the weight coefficient of each factor. Through calculating the comprehensive evaluating value of thirteen blocks in the area, theforming conditions in East Harbin Block are proven to be the most favorable for hydrocarbon accumulation in Fuyu oil layers of Songbei exploratory area, and the next is Binxian and Mulan blocks.
