在对辽中凹陷3个主要油气藏原油物性分布特征进行研究的基础上，结合构造地质条件，分析了影响原油物性特征的主要因素．研究认为，原油物性不仅受到族组成的影响，还与油源差异、原油保存条件、重力分弄作用等有密切关系．运移方向上，随着运移距离的增加，原油物性不断变差．纵向上，在保存条件较好的情况下，原油物性随着深度的增加而变差；反之，物性则逐渐变好．同时通过分析物性之间的关系，发现密度和粘度有很好的正相关性．与粘度相比，密度和合蜡量有着更密切的关系．

Based on research on physical properties and the distribution characteristics of crude oil about three main reservoirs in Liaozhung sag, combining the structural geology condition, the authors analyze the main influencing factors of the physical properties of crude oil. By means of studying, physical properties of crude oil are not only influenced by group compositions, but also closely related to oil source differences, the preservation conditions of crude oil and the gravitational differentiation. Physical properties of crude oil gradually become poor along the lateral migration pathways. In the vertical, under well preservation conditions, physical properties of crude oil become poor with the increase of depth. Instead of cases, they become well. Meanwhile,it is found that density and viscosity present good positive correlation via analyzing the relationship between physical properties of crude oil. Compared with viscosity, density and wax content reveal a more close relationship.
