A treatment fluid may comprise: a water having hardness at about 300 ppm or greater, a plurality of particulates, a swellable clay, a chelating agent at about 0.01% to about 5% by weight of the water (BWOW); and an alkali metal base at about 0.01% to about 5% BWOW, wherein the chelating agent and alkali metal base reduce the negative effect of the water on hydrating swellable clays.
处理液可包括:硬度约为 300 ppm 或更高的水、多种微粒、可膨胀粘土、占水重量约 0.01% 至约 5% 的螯合剂;以及占水重量约 0.01% 至约 5% 的碱金属碱,其中螯合剂和碱金属碱可减少水对可膨胀粘土水化的负面影响。
