摘　　要：从蜡与固体壁面间的界面性能考虑,在管道内壁涂覆一层低表面能的树脂涂层,可以改变管壁表面性质,减小管壁与蜡之间的相互作用力,达到防止结蜡的目的。为改善高含蜡原油在管道输送时易凝和粘滞的状况,在实验室用自行设计的结蜡器评价了硅、氟树脂以及丙烯酸树脂等涂层在青海原油、胜利原油和辽河原油输送中的防结蜡效果。结果表明,它们有不同程度的防结蜡作用,其中硅树脂的最大防蜡率可达74.7％。In consideration of the interfacial performance between wax and pipe wall, the property of wall surface can be changed by coating a low surface energy resin on the internal wall of the pipelines, which can reduce the interaction between the wax and wall for inhibiting wax deposition. The wax deposition inhibiting efficiency of resin coatings on crude oil transportation was evaluated by using a wax deposition apparatus. The evaluation result showed that the coatings of fluorine, silicone and acrylic resins all had good wax deposition inhibiting efficiency, the silicone resin ranked first, it reached 74.7%.
