| 摘 要： | 在分析重力热管改善抽油井井筒热损失原理的基础上，进行了重力热管井筒伴热室内物理模拟试验和矿场试验。室内复配出的工质A液，与水基工质相比，具有液体密度小、蒸气密度高的优点，适合进行重力热管传热。室内模拟重力热管井筒温度分布结果表明，重力热管冷凝段与蒸发段的温度之比大于0.7，能够有效改善井筒流体温度分布。矿场试验结果表明，在蒸汽吞吐过程中采用重力热管井筒伴热技术，能够有效减小井筒流体温度下降的幅度，延长油井的生产时间，增加蒸汽吞吐周期的产量。

| Abstract: | Based on the analysis of gravity heat pipe to decrease heat loss through wellbore during thermal recovery,indoor experiments and field tests were conducted.Working fluid A had lower fluid density and higher gas density compared with water based fluid,therefore fluid A was suitable for heat transfer in gravity heat pipe.The wellbore gravity heat pipe temperature distribution form experiment shows that when condensation temperature and evaporation temperature ratio was higher than 0.7,the gravity heat pipe wa... |
