A water-based wellbore treatment fluid contains: one or more viscoelastic-gelling carboxylic acids and/or alkali metal salts thereof; and one or more solubilising alkylolamines. The carboxylic acids and/or alkali metal salts and the alkylolamines are present in the fluid in respective amounts such that, at 25° C., the alkylolamines solubilise a sufficient portion of the carboxylic acids and/or alkali metal salts to render the fluid viscoelastic. A remaining portion of the carboxylic acids and/or alkali metal salts forms a suspension of solid particulates in the fluid.
一种水基井筒处理液包含:一种或多种粘弹性凝胶羧酸和/或其碱金属盐;和一种或多种可溶化烷基醇胺。羧酸和/或碱金属盐和烷基醇胺以各自的数量存在于液体中,使得在25°C下,烷基醇胺可使足够的羧酸和/或碱金属盐溶解以使液体具有粘弹性。剩余的羧酸和/或碱金属盐形成液体中的固体颗粒悬浮液。
