Catalyzed polyamine sulfide scavengers and methods of use in subterranean treatment fluids |
摘要 |
Improved methods and additives for eliminating or reducing concentrations of hydrogen sulfide or soluble sulfide ions for use in subterranean formations and fluids are provided. In one embodiment, the methods comprise: providing a treatment fluid comprising an oil-based liquid and a sulfide scavenging additive comprising one or more polyaliphatic amines and a catalyst comprising one or more quaternary ammonium salts; introducing the treatment fluid into at least a portion of a subterranean formation; and allowing the sulfide scavenging additive to interact with hydrogen sulfide or sulfide ions present in the treatment fluid. |
