【摘要】 研制开发出组成独特、清防蜡效果很好的DQ系列清防蜡剂和结构新颖且降凝、降粘效果很好及抗剪切性能较好的BEM、EAP系列降凝降粘剂。DQ清防蜡剂已在大庆、新疆等油田应用,延长油井热洗周期5倍以上;BEM降凝降粘剂已在鲁宁、中洛等长输管线上应用,大幅度降低了原油的凝点、粘度,并取得了可观的经济社会效益。更多还原

【Abstract】 DQ series of dewaxing and wax inhibiting agents which have an unusual composition and a very good dewa-xing, wax inhibiting effect, and BEM series of pour point reducer/viscosity-reducer agents which have a novel structure and a very good pour point reducing, viscosity reducing effect, and a better shear resistant function, had been developed. DQ has already been used in Daqing, Xinjiang oilfields, well-washing cycle of the oil well was lengthened by above five times; and BEM has already been used in Luning, Zhongluo and other long distance pipelines, pour point and viscosity of the crude oil were remarkably reduced, and considerable economic, and social benefits were obtained.更多还原
