摘要： Solid surfactant suspension compositions are formed by combining solid surfactants, such as alpha-olefin sulfonates, with an organic base fluid, such as diesel. Solid surfactant suspensions may be combined with an aqueous carrier fluid to form surfactant-containing fluids suitable for, among other things, forming foams or for water wetting surfaces. Solid surfactant suspensions may also be combined with additive materials, such as polymer particles, to form a dispersion or emulsion. Polymer-containing solid surfactant suspensions may also be combined with aqueous carrier fluids to form, for example, viscosified, gelled, or foamed fluids. Concentration of solid surfactant materials contained in a solid surfactant suspension may be varied to affect the function the solid surfactant suspension. For example, the solid surfactant material may function as a polymer surface wetting agent, an emulsifier, a dispersant, a viscosifier, and/or a foamer in well completion and remedial and/or workover fluids.
摘要翻译：固体表面活性剂悬浮液组合物通过将固体表面活性剂如α-烯烃磺酸盐与有机基础流体如柴油混合而形成。固体表面活性剂悬浮液可以与含水载体流体组合以形成适于尤其形成泡沫或用于水润湿表面的含表面活性剂的流体。固体表面活性剂悬浮液也可以与添加剂材料如聚合物颗粒结合以形成分散体或乳液。含聚合物的固体表面活性剂悬浮液也可以与含水载体流体混合以形成例如粘稠的，胶凝的或发泡的流体。包含在固体表面活性剂悬浮液中的固体表面活性剂材料的浓度可以变化以影响固体表面活性剂悬浮液的功能。例如，固体表面活性剂材料可用作完井和补救和/或修井液中的聚合物表面润湿剂，乳化剂，分散剂，增粘剂和/或起泡剂。
