    • A solution composite is provided to improve the flowing characteristic of heavy oil at a low temperature, thereby preventing the reduction of oil flux occurring while oil is transferred through a pipe. A solution composite contains ammonium polyoxyethylene alkylaryl ether sulfate of a formula 1 and a solvent. In the formula 1, R is an aliphatic series selected from a group consisting of alkyl, alkylene, alkoxy alkyl ranged from 1 to 36 of carbon number, and n is an integer of 1 to 1000. The ammonium polyoxyethylene alkylaryl ether sulfate has a content of 20-80 weight percents based on the total weight of the solution composite. The solvent has a content of 20-80 weight percents based on the total weight of the solution component. The solvent is selected from a group consisting of ethylene glycol monobuthyl ether, diethylene glycol monobuthyl ether, aromatic naphtha solvent, and methyl ether.
