Self-degrading ionically cross-linked biopolymer composition for well treatment |
摘要 |
A method of treating a well including the steps of: (A) forming a treatment fluid comprising: (i) water; (ii) a water-solubleβ-polysaccharide selected from the group consisting of aβ-galactomannan, a water-soluble derivative thereof retainingβ-O-glycosidic linkages and a mannose:galactose of at least 5:1; and any combination thereof; (iii) a borate cross-linker; (iv) a base to adjust the pH of the water in the treatment fluid to be at least 8.5; and (v) a water-solubleα-polysaccharide or water-soluble derivative thereof retainingα-O-glycosidic linkages; and (B) introducing the treatment fluid into the well. |
