摘　　要：原油组分决定原油的结构力学性质,使其具有不同的渗流流变特性。实验表明原油胶质、沥青质、石蜡的含量及是否含气等内因决定着原油自身的流变特性;而温度、多孔介质的渗透性以及非流动相是否存在等外因,则将影响原油的渗流特性,具有结构性的原油在低速渗流时将呈现出不同的非线性渗流特征。The component of crude oil determines its textural mechanical properties, and causes different percolation rheological characteristics. The experiments show that the intrinsic factors such as colloid, bitumen and wax content determine its rheological properties, while the external factors such as temperature and permeability of porous medium as well as the existing of non-flowing phases will have some influence on the percolation characteristics of crude oil. The textural crude oils will have different non-lineal percolation characteristics at low flowing velocity.
