| 中文摘要:油页岩作为一种非常规油气资源,有望成为石油的替代品。油页岩原位裂解技术对环境污染小,生成的油页岩油油品好,具有良好的开发前景。在原位裂解过程中,减少注热过程中的热量损失具有十分重要的意义,因此本文将对保温注热管柱的传热特性进行数值模拟和试验研究。通过传热学计算分析,保温注热管柱设计为外径?32mm的钢管,外层缠绕共计24mm的纳米保温材料。数值分析表明氮气流量越大,注热管柱出口温度达到稳定的时间越短,稳定温度也越高；当管柱氮气入口温度为500℃时,管柱出口温度在一定注气时间后均可达到400℃以上。在农安油页岩原位裂解先导试验工程中对注热管柱进行野外试验,管柱达到注热保温效果,井底温度达到设计温度,最终成功获得油页岩油。 |

| Abstract:As an unconventional oil and gas resource, oil shale is expected to be a substitute for oil. At present, the underground oil shale in situ pyrolysis technology has better prospects due to its good product quality and environment friendly to surroundings. The pyrolysis temperature is the key factor of oil shale in situ pyrolysis, so it is of great importance to reduce the heat loss of the heat injection pipe. Therefore, the heat transfer characteristic of heat injection pipe column for in situ pyrolysis is studied by numerical simulation and field test. According to the heat transfer calculation, the heat preservation and injection pipe column is designed to be a steel pipe with outer diameter of 32mm, and the outer layer is wrapped with 24mm thick aerogel. The numerical analysis shows that the larger the N2 injection flow rate is, the shorter the time to reach the steady temperature at the heat pipe column injection outlet can be; when the N2 inlet temperature of the pipe column is 500°C, the outlet temperature can reach 400℃ a certain time after gas injection. Field experiments are carried out on heat injection pipe column in Nong’an oil shale in situ pyrolysis pilot test project, the heat preservation effect is obtained and the temperature at the well bottom reaches the designed value, shale oil is successfully mined. |
