Selected sulfur-containing compounds function as solution viscosity stabilizers in aqueous compositions comprising acrylamide polymers containing a redox couple or components which can produce a redox couple in the presence of the solution. The aqueous compositions are useful in post-primary oil recovery involving the use of thickened fluids as mobility buffers and mobility control agents.
选定的含硫化合物在水性组合物中可用作溶液粘度稳定剂,该水性组合物包含含有氧化还原对偶的丙烯酰胺聚合物或在溶液存在下可产生氧化还原对偶的成分。这种水性组合物可用于初级采油后,将增稠流体用作流动性缓冲剂和流动性控制剂。
