系列化石油磺酸盐与胜利原油相互作用的研究

研究了胜利石油磺酸盐及其系列化产品与胜利原油及其组分之间的界面张力，结果表明，原油组成的差别造成磺化产品性质的差别；同一石油磺酸盐产品不能适应不同区块原油低张力的要求，必须复配适宜的助表面活性剂，而系列化石油磺酸盐与本区块油水具有较好的相似相容性，低浓度下不复配任何助表面活性剂就具有较高的界面活性。

Study on Interfacial Tension between Series of Petroleum Sulfonates and Shengli Oil

The interfacial tension between Shengli petroleum sulfonates or series of petroleum sulfonates and shengli oil with different components was studied. The result showed that the difference in properties of petroleum sulfonates was a result of difference in compositions of shengli oil with different content of saturated hydrocarbon, aromatic hydrocarbon and polar components. The same petroleum sulfonate couldn't be used in oils from different oil fields with the interfacial tension not low enough to meet the demands. Suitable surfactant aids should be added. Series of petroleum sulfonates had good compatibility with the oil and water in the same oilfield. High interfacial activity could be obtained without adding any surfactant aids by using the above series of petroleum sulfonates in low content.
