The major characteristic of GMH-1 sulphosalts anionic surfactant is that it can maintain good chemical properties under high temperature conditions, and has good continuous foaming capacity with the decomposition temperature over 300℃. It can form foams through reaction with air, nitrogen or carbon dioxide. Due to its strong foaming capacity, high foam stability and strong temperature resistance, its capacity is superior to similar products and it has good co***tibility with other chemical additives. In the process of steam stimulation or steam drive, foaming agent applied can inhibit channeling, modify the injection profile, improve the steam injection efficiency, extend the steam injection cycle, and enhance single well oil production. |
