【Abstract】 A compounded low-cost surfactant ZHA is developed and its properties are evaluated in this paper.Through lab.research,the results show that the production’s interfacial activity,heat-resistance and salty tolerance are excellent,the IFT between ZHA and acidic heavy oil can reach 10 -3mN/m,its heat-resistance can reach 120°C,sodium ion tolerance can reach 20000ppm and calcium ion tolerance 350ppm.The cost of ZHA is low and its costs are less than half of common-used surfactants OP-10 and petroleum sulfonate.更多还原
