The Preparation and Characterization of AM/2-EHA/VTEOS Copolymer as Profile Control Agent

Abstract:

In order to enhance oil recovery and avoid the profile control agents degradation in the alkali/surfactant/polymer composite solution in the oil layer, the copolymer of AM (basic monomer), 2-EHA (salt resistance monomer with large lateral group) and VTEOS(temperature tolerance monomer) was prepared by free radical copolymerization method as the profile control agent. FT-IR and 1H-NMR were used for the structure characterization. Thermo gravimetric analysis, Core/Sand pack experiments and water drive displacement tests of copolymer particles were used to evaluate the properties. The results shows that the copolymer particles have good thermal stability, alkaline resistance, anti-salt property and excellent blocking property as profile control agent.
