The aromatic-hetero fused ring planes of the asphaltene molecules are overlapped and stacked together and are fixed by hydrogen bonds between polar groups, and the aromatic-hetero fused ring planes are stacked into particles and then are aggregated into asphaltene micelles with different sizes. Colloid molecules are stacked on the surface of the asphaltene particles in an overlapping way by an aromatic fused ring plane and are fixed by hydrogen bonds to form a coating layer for the asphaltene particles. The particles can be connected with each other through hydrogen bonds to form micelles with large molecular weight, so that the high viscosity of the thick oil is caused.
