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

总部位于尼斯库的希龙石油管道有限公司提供各种管道涂层选项，旨在防止钻杆和油管的内表面免受井下侵蚀和磨损，并减少摩擦和湍流，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良好，但也有一些客户反映，涂层油管在满足冷稠油出砂(CHOPS)井的生产要求方面存在一些困难。由于希龙公司的油管涂层设计用于传统的轻质油井，因此它们在加拿大CHOPS油井中的表现是否同样好是值得怀疑的。这项研究的总体目标是通过检测含砂稠油在这些涂层油管中的流动效率，初步评价希龙公司内涂层在钻井液中的性能。该项目的研究成果有助于希龙开发出性能更好的钻井液用新型涂料产品。

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.
