摘　　要：针对油田开发实际,研究了温度、醇、烷烃、无机盐、油田水质矿化度、聚合物等因素对烷基羧酸钠——油酸钠(NaOA)在磷酸钠(Na3PO4)存在条件下形成的蠕虫状胶束流变性质的影响。不仅从理论上对蠕虫状胶束的零剪切粘度、剪切活化能等流变性质进行了分析和解释,而且为拓宽阴离子蠕虫状胶束在石油开采领域的应用提供了依据。The effects of various factors on rheological properties of wormlike micelles formed by sodium carboxylate, namely sodium oleate （NaOA） aqueous solution in the presence of trisodium phosphate （Na3 PO4 ） were investigated. These factors include temperature, alcohols, alkane, inorganic salts, the mineralization of oil field water and polymes, which are frequently encountered in the oilfield development process. The rheological properties of wormlike micelles, such as zero shear viscosity and shear activation energy were analyzed and explained. These studies provide the basis of applications of wormlike micelles to oilfields.
