For this situation, prepared by the excellent performance of high-temperature foaming agent C20-24α-olefin sulfonate. Determination of apparent surface tension, foaming agent has good interfacial activity. The foaming agent use C20-24α-olefin sulfonate neutralization reaction. Determination by Waring Blender stirring foaming agent foaming volume and half-life, to evaluate the oil effervescent systems, temperature, salt and other properties. The results showed that the foaming agent solution concentration of 0.8%, the bubble size and half-foaming agent is maximized; foaming agent solution temperature was above 90 ℃, salt tolerance in more than 5% for basic and neutral environment. Crude oil has obvious anti-foaming, greater oil saturation, the more obvious anti-foaming.
