摘要：NOVELTY - The elastic-viscous gel containing surface agent. The elastic-viscous gel is mainly formed by low-polymer anion surface activator, cetyl trimethyl ammonium bromide and deionized water. The concentration of low-polymer anion surface activator is 1.5-2.5wt%; the concentration of cetyl trimethyl ammonium bromide is 3.9-7.0wt%; and the structure of low-polymer anion surface activator is (1). The invention has better elasticity, thixotropy and shear thinning property, which can supply oil production. And in (1), R1 is C10-C16 alkyl; R2 is SO3H, SO3M, or ; M is K or Na.
