CA 2742431

The present invention relates to a surfactant and preparation and use thereof. The surfactant is formed by copolymerization of monomer (A) and monomer (B), said monomer (A) is one or more unsaturated monomers with strong lipophilic group, having the general formula (1), wherein R, R1 and R2, whether the same or different, represent H or C1-C12 alkyl; said monomer (B) is one or more unsaturated monomers with weak hydrophilic group, having the general formula (2), wherein R3 represents H or C1-C4 alkyl; A represents COOM, OM, or SO3M, and M represents H, Na+, K+, C1-C8 alkyl, C1-C8 alkyl ether or C1-C8 alkyl ester; wherein monomer (A) comprises from 10% to 90% by weight of the total weight of monomer (A) and monomer (B); and monomer (B) comprises from 10% to 90% by weight of the total weight of monomer (A) and monomer (B). The surfactant is used in exploitation, gathering and transportation of heavy oil having a viscosity of more than 2,000 mPa.s. (see formula 1)(see formula 2)
