摘要:

原油胶质中含氮、氧等杂环结构的强氢键作用使原油易黏附于包括特氟龙在内的各类材料,导致原油开采、输送、储存和加工过程中采油井筒、输油管道、容器和设备等长期存在污损污堵技术问题。目前仍少见针对原油为对象的防黏附材料的研究工作,防黏附材料对原油输送等原油流体是否具有减阻效果尚缺少研究结论。基于硅基类液防黏附功能涂层研制,系统研究了涂层对原油防污自洁功能及功能的长效稳定性。研究了防黏附功能涂层对原油的减阻效应,并对不同原油流动性、黏度等条件下涂层的减阻作用进行了理论计算。结果表明涂层对不同黏度原油均具有良好的防黏附和减阻效果,对比无涂层的条件,涂层对黏度越高原油的减阻效果相对越显著。研究结果为原油输送等相关减阻涂层材料的科学设计与可控制备提供了理论、材料与技术支撑。

Abstract:

The strong hydrogen bonding of nitrogen and oxygen heteroring structures in crude oil makes crude oil easy to adhere to different kinds of materials including Teflon, resulting in fouling and blockage challenges of oil wells, pipelines, containers and equipments in the process of crude oil exploitation, transportation, storage and processing. At present, there is still little research on anti-adhesion materials targeting crude oil, and there is still a lack of research conclusion on whether anti-adhesion materials have drag reduction effects on crude oil fluids such as crude oil transportation. In this paper, based on the development of silicon-based liquid-like anti-adhesion coatings, the coating's antifouling and self-cleaning function and their long-term stability were systematically studied. The drag reducing effect of the anti-adhesion functional coating on crude oil was studied, and the drag reducing effect of the coating under different crude oil fluidity, viscosity and other conditions was theoretically calculated. The results indicated that the coating exhibited outstanding anti-adhesion and drag reduction effects on crude oils of different viscosities. Compared with the conditions without coating, the drag reduction effect of the coating on higher viscosity crude oils is relatively more significant. It provides theoretical, material and technical bases for the scientific design and controllable preparation of drag reduction coating materials for the application such as crude oil transportation.
