摘　　要：粘度高密度大的稠油,其物理特性与一般原油有着很大的区别。在描述了国内外的稠油分类标准和稠油基本特征的同时,对大庆油田稠油的高压物性实验结果与黑油的高压物性资料进行了对比研究。结果表明,大庆油田稠油表现出油藏埋藏浅地层原油粘度高密度大含气、含蜡量少和饱和压力低的特点。分析后认为大庆油田的稠油适合于热蒸汽驱开发,并在进行热力采油时,不必过多考虑压力及溶解气因素。The physical properties of viscous oil of high viscosity and density differ greatly from common crude oil. The paper has described the domestic and foreign classification standards and basic properties of viscous oil. At the same time, a correlation study has been carried out between the high pressure physical properties experimental result of viscous oil and the high pressure physical properties data of black oil in Daqing oilfield. The result indicates that the viscous oil in Daqing oilfield is featured by shallow buried depth, high inplace oil viscosity and density, low gas and paraffin contents and low saturation pressure. Analysis leads to conclusions that hot steam injection recovery mode should be suitable for viscous oil development in Daqing oilfield and that pressure and dissolved gas factors should not be over considered in thermal recovery.
