Hightemperaturefoamingagent

High temperature foaming agent is a kind of sulfate anion surface active agent, the utility model is mainly characterized in high temperature to maintain good chemical properties, and good continuous foaming capacity, decomposition temperature above 300 ℃. Mainly used for the three production of foam flooding, cyclic steam injection, steam flooding, but also can be applied to the field of foam drilling, foam acidizing, profile control and water shutoff, foam drainage gas recovery and many other fields; and air, nitrogen, carbon dioxide can form good foam, foaming capacity, foam stability, resistance warm and strong, performance is superior to the same type of products, and other chemical additives have good compatibility. In the steam stimulation or steam flooding, adding foaming agent can inhibit gas channeling, adjust injection profile, improve the gas injection efficiency, prolong the gas injection cycle, increase single well crude oil production.
