摘要
Abstract
The molecular structure of viscosity reducer is designed according to the cause of the high viscosity of heavy oil and the viscosity-reducing mechanism of viscosity reducer. Firstly,a meddle product of terpolymer ASAM is synthesized using acrylic acid ( A) , styrene (S) ,acrylamide (AM) ,and then the viscosity reducer ASAM/ C/ O is synthesized with the terpolymer ASAM,polyols,long chain alkyl acid. The synthetic conditions of the terpolymer ASAM and the viscosity reducer ASAM/ C/ O are optimized and their optimum conditions are obtained by orthogonal experiments. The optimal synthesis conditions of ASAM are that, the mass ratio of A, S to AM is 6:3:2,the mass fraction of initiator is 1.3% ,and reaction time is 6 h. The optimal synthesis conditions of ASAM/C/O are that,the mass ratio of ASAM,C to 0 is 6:2:1.5,the carbon chain length of alkyl acid is 18,reaction temperature is 110 ～ 120 ℃ ,and reaction time is 6 h. The viscosity reducer ASAM/ C/ O has good reducing-viscosity performance. Its reducing-viscosity ratio will increase with the decreasing of temperature. The viscosity and activation energy of the heavy oil adding the viscosity reducer ASAM/ C/ O into are greatly decreased,which shows the heavy oil system has weaker structure.关键词
