研究了用石油馏分液相氧化产物制得的石油羧酸盐与不同磺酸盐 (ORS 41、B 10 0、MS 45等 )的复配体系的界面活性。结果表明 ,复配体系的界面活性优于单一的石油羧酸盐或磺酸盐体系。将少量磺酸盐与石油羧酸盐复配 ,可使体系达到超低界面张力所需的矿化度大大降低 ,碱度范围大为拓宽 ,达到超低界面张力值所需的时间大为缩短 ,初始界面张力很低。复配体系的这些特点对提高驱油效率很有利
The interfacial activity of the petroleum carboxylate prepared with the liquid phase oxidation of petroleum fractions with different sulfonates (ORS 41, B 10 0, MS 45, etc.) was investigated. The results show that the interfacial activity of the complex system is better than the single petroleum carboxylate or sulfonate system. The combination of a small amount of sulfonate and petroleum carboxylate can greatly reduce the degree of salinity necessary for the system to achieve ultra-low interfacial tension, broaden the range of alkalinity and shorten the time required to reach ultra-low interfacial tension values , The initial interface tension is very low. These characteristics of compounding system are very beneficial to improve the efficiency of oil displacement
