| 摘 要： | 多数表面活性剂复合体系与葡北原油不匹配，主要原因是活性剂平均当量较高。而葡北原油组成与长垣主力油田的原油不同：葡北原油的胶质沥青质含量较低、碳数分布曲线向低碳偏移，平均相对分子质量偏低。某些批次植物油羧酸盐表面活性剂虽然能形成超低界面张力，但由于产品本身稳定性差、体系热稳定性差等原因难于采用。

| Abstract: | Most surfactant systems do not match with the oil of northern Putaohua Oil Field.The reason is the high value of the average equivalent of surfactant.The oil composition in this area is different with the major oil fields in the placanticline: it has a low content of asphaltenes, carbon number distribution curve shifting toward low carbon,and low average relative molecular quality.Certain batches of vegetable oil carbonxylate surfactant can for an ultra-low interfacial tension,but it cannot be used because of its poor stability. |
