摘要:
Sulfonated betaines amine oxides, and sultaines are made by the reaction of the corresponding unsaturated betaines or sultaines. These are formulated into injection fluids suitable for the recovery of residual oil from subterranean reservoirs. The sulfonated betaines, amine oxides, and sultaines exhibit lower adsorption onto reservoir rock compared to their corresponding unsulfonated betaines, amine oxides, and sultaines. They can be used in applications where their respective amphoteric surfactants are currently used such as personal care, mining, improved oil recovery (IOR), oil field drilling, fracturing, acidizing, foaming, oil field stimulation, and agricultural formulations.
