发明名称 PRECIPITATION PREVENTION IN PRODUCED WATER CONTAINING HYDRATE INHIBITORS INJECTED DOWNHOLE
摘要 The precipitation of polymeric kinetic hydrate inhibitors (KHIs) in stored produced water is prevented or inhibited by incorporating a water immiscible solvent therein having a polarity index greater than about 3. The polymeric KHIs whose precipitation is inhibited or prevented include, but are not limited to, hyperbranched molecules, polyvinylcaprolactam, polyvinylpyrrolidone, and the like. Suitable water immiscible solvents include, but are not necessarily limited to, xylene, toluene, kerosene, mineral spirits, trimethylbenzene, cumene, heavy aromatic naphtha, ethylbenzene, polyethylbenzene, naphthalene, and mixtures thereof.
