摘　　要：在实验室对BEM系列复合型原油流动性改进剂的研究结果表明:乙烯-醋酸乙烯酯(EVA)中的醋酸乙烯酯(VA)的含量和熔融指数对含蜡原油降凝效果有直接影响,将不同VA含量和熔融指数的EVA进行复配,对含蜡原油有较好的降凝效果;添加有较大的空间结构和较长直链的表面活性剂对原油流动性改进剂抗重复加热和抗剪切能力的改善效果最好;BEM剂对含蜡原油的最佳加入量一般不低于40μg/g;添加BEM-3剂的含蜡原油静态稳定72h,动态稳定168h后降凝效果变化不大。Preparation of BEM series complex pour point depressant was conducted in the la-boratory. The research showed that the melt index and the content of principal component, vinyl acetate (VA), of ethylene-vinyl acetate (EVA) had direct effect on the pour point depressing of waxy crude. The EVA having certain VA and melt index exhibited promising pour point depressing result. Adding surfactant with larger steric structure and longer linear chain could significantly improve the anti-repeat-ed heating and shear-resistant properties of the pour point depressant. The optimum dosage of BEM agent into the waxy crude was not less than 40μg/g. The pour point depressing effect of the BEM-3 add-ed waxy crude was basically no changes after 72h static stabilizing and 168h dynamic stabilizing.
