Abstract: 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.
