METHODS FOR ACIDIZING SUBTERRANEAN FORMATIONS AND GELLED ACID COMPOSITIONS |
| 摘要 |
<p>Gellable and gelled acid compositions comprise an aqueous acid and a water-soluble polymer comprising, for example, acrylamide, an N-sulfoalkyl ethylenically unsaturated amide, and a polyvinyl crosslinking monomer. The gelled acids are useful in acidizing subterranean formations and such gels are stable to degeneration by heat.</p> |
