Flow Efficiency and Erosion Characteristics of Internally Coated Tubing in CHOPS Wells

位于Nisku的海隆石油管道有限公司提供多种管道涂层选择，旨在防止钻杆和油管的内表面受到井下侵蚀和磨损，减少摩擦和湍流，从而提高油井的流动效率。尽管客户对涂层服务的总体反馈很好，但一些客户反映涂层油管在满足含砂冷稠油生产（CHOPS）井的生产要求方面存在一些困难。由于海隆的油管涂层是为常规轻油井设计的，因此在加拿大油气井中是否也能发挥同样的作用还值得怀疑。本研究的总体目标是通过检测这些涂层油管中含砂稠油的流动效率，初步评估海隆内部涂层在chop井中的性能。该项目的研究成果有助于海隆开发性能更好的新涂层产品。

Based in Nisku, Hilong Petropipe Company Ltd. provides a variety of pipe coating options designed to prevent the internal surfaces of drill pipes and oil tubing against downhole erosion and abrasion, as well as reduce the friction and turbulence, thus enhancing flow efficiency in oil wells. Despite the overall good feedback from the customers on the coating service, some customers have reported some difficulty for the coated oil tubing to meet the production requirements in Cold Heavy Oil Production with Sand (CHOPS) wells. Because Hilong's tubing coatings are designed to be used in conventional light-oil wells, it is questionable if they perform equally well in Canadian CHOPS wells. The overall objective of this study is to primarily evaluate the performance of Hilong' internal coatings in CHOPS wells through examining the flow efficiency of sand-laden heavy oil in these coated tubing. The research results from this project help Hilong to develop new coating products that perform better for CHOPS wells.
