摘　　要：针对稠油油管油垢堆积、清洗难等问题,结合理论研究、数值模拟及现场试验,设计出一种蒸汽射流清洗喷嘴。数值模拟结果表明,蒸汽射流喷嘴内的温度和压力在管内呈梯度分布,可提高蒸汽射流在稠油管内的凝结潜热释放效率,有效清洗附着于管壁的稠油油垢;现场试验表明,该喷嘴可有效提高稠油油管的清洗质量,相比直喷嘴能达到更好的清洗效果。稠油油管蒸汽射流清洗喷嘴及其装置,可大幅提高我国稠油开采区内稠油油管清洗修复工作的效率。Aiming at tubing for heavy grease accumulation,being difficult to clean and other is-sues,combining theoretical studies,numerical simulation and field trials,a steam jet nozzle is de-signed.Simulation results show that the temperature and pressure inside the steam jet nozzle gra-dient distribution in the tube.It can increase the release of latent heat of condensation of steam jet efficiency in the heavy tube and effectively clean heavy grease attached to the wall,which can play a good cleaning effect.Field tests show that the cleaning nozzle can effectively improve the quality of heavy oil pipe,which can achieve,better cleaning effect compared to a straight nozzle.The de-vice can significantly increase the area of heavy oil recovery of heavy oil pipe cleaning repair work efficiency and economic benefits.
