摘　　要：通过对黄河口凹陷不同层位的原油物性特征进行统计,结果表明:原油物性不仅受原油族组成的影响,而且也受成熟度、埋藏深度、保存条件和组分重力分异作用的影响。原油相对密度的影响因素较多,主要包括饱和烃、芳香烃、胶质含量、沥青质和含蜡量等;而原油黏度主要受饱和烃、芳香烃、胶质含量的影响,沥青质和含蜡量对其影响不大。分析认为,影响黄河口凹陷原油物性的因素很多,其中油源差异、生物降解、油气运移以及保存条件等是导致该区原油性质差异性的主要因素。Statistics from oil physical properties of main strata in Huanghekou depression show that physical characteristics of oil depend not only on group compositions, but also on maturity, burial depth, preservation condition and compositional gravity differentiation. The factors influence on density, include content of saturated hydrocarbon, aromatic hydrocarbon, resin, asphaltene and wax. Viscosity mainly depends on content of saturated hydrocarbon, aromatic hydrocarbon and resin, not on asphltene and wax. The authors believe that the distribution role of physical properties of oil in Huanghekou depression is the result of multi-factors combinations. Among all the factors, hydrocarbon source differences, biodegradation, migration and the reservoir preservation condition are the main influence factors resulting in discrepancy of physical properties.
