METHODS AND SYSTEMS FOR IRON CONTROL USING A PHOSPHINATED CARBOXYLIC ACID POLYMER |
摘要 |
The presence of iron in a subterranean formation, particularly ferric iron, can be problematic during an acidizing operation due to sludge formation that can occur. Methods for treating a subterranean formation in the presence of iron can comprise: providing a treatment fluid comprising an acid and an iron stabilization agent comprising a phosphinated carboxylic acid polymer, the treatment fluid having a pH of about 3 or below and the phosphinated carboxylic acid polymer being soluble in the treatment fluid; introducing the treatment fluid into a subterranean formation; and interacting the phosphinated carboxylic acid polymer with ferric iron in the subterranean formation. |
