摘　　要：对一种新型高分子表面活性剂PS 1(丙烯酰胺、丙烯酸、甲基丙烯酸甲酯的三元共聚物 )的增粘性能、稳泡性及洗油能力进行了实验室研究。高分子表面活性剂不仅有很强的增粘能力 ,而且能在一定程度上降低液体的表面张力。实验结果表明 ,高分子表面活性剂在稳定泡沫和提高驱油效率方面都比低分子表面活性剂优越 。A surfactant PS-1 (a copolymer of acrylamide, acrylic acid and methyl methacrylate) with high molecular weight and high viscosity has been studied for EOR. Some characteristics of the product such as thickening, foam stability and oil displacement have been studied in the lab. Lots of scientific data show that the product can increase the viscosity of solution significantly and improve the stability of foam. These characteristics are good for improving the efficiency of oil displacement over low molecular weight surfactant and have widely prospects in EOR.
