Gelled aqueous compositions. |
摘要 |
<p>Disclosed are gelled compositions in fresh water or brine solution, containing a polymer selected from the group consisting of water-soluble anionic or nonionic polymers capable of gelling in the presene of a gelling agent characterized in that the gelling agent is a water-soluble cationic poly(N-alkyldiallylamine)-epihalohydrin resin in an amount sufficient to cause a gel to form. The compositions are useful in the recovery of oil and gas by fracturing and as a matrix plugging agent in enhanced oil recovery.</p> |
