To provide a salt water thickener that uniformly (favorably) disperses fine cellulose fibers even in a liquid containing a salt (electrolyte).SOLUTION: The salt water thickener comprises fine cellulose fibers and a water-soluble polymer and can thereby uniformly disperse the fine cellulose fibers even in a liquid containing a salt. The salt water thickener of the present invention is uniformly dispersed even in a liquid containing a salt and therefore exerts a high viscosity. The salt water thickener of the present invention can also be used as an additive for a fluid. The salt water thickener of the present invention can be used for purposes, for example, subterranean formation processing.SELECTED DRAWING: None 【課題】塩（電解質）が存在する液中でも、微細セルロース繊維が均一（良好）に分散する塩水用増粘剤を提供することを課題とする。【解決手段】微細セルロース繊維と水溶性高分子を含む塩水用増粘剤とすることにより、塩を含む液中でも微細セルロース繊維を均一に分散させることができる。本発明の塩水用増粘剤は、塩を含む液中でも均一に分散するため、高い粘度を発揮する。また、本発明の塩水用増粘剤は、流体への添加剤として用いることもできる。例えば、地下層の処理などの用途に用いることができる。【選択図】なし
