采用生物可降解的耐盐水性成泡组合物增强油回收的方法
摘要：
本发明涉及一种用于增强油回收的成泡组合物和其使用方法。所述成泡组合物包含阴离子型磺酸盐表面活性剂，其中所述阴离子型磺酸盐表面活性剂可生物降解并具有低水生毒性。用于从储层回收油的所述方法包含周期性地注射气体和所述成泡组合物到所述储层并使所述储层中的所述油与所述泡沫接触以便帮助油从所述储层回收。
摘要（英）：

This invention relates to a foam-forming composition and method of use thereof for enhanced oil recovery. Said foam-forming composition comprises an anionic sulfonate surfactant wherein the anionic sulfonate surfactant is biodegradable and has low aquatic toxicity. The method for recovering oil from a reservoir comprises the periodic injection of gas and said foam-forming composition into the reservoir and contacting the oil in the reservoir with the foam so as to assist in the recovery of oil from the reservoir.
