热采可能是提高采收率（EOR）技术中最重要的方法，特别是对于稠油开采来说，它被定义为将热能引入储层地下以回收燃料的一种进步。热采过程的应用主要是对油井中热能输送的研究。对热采过程的现场行为进行预测，需要准确计算注入储层的热能，因此开展了一系列井筒、地层和储层的热输运分析工作，以模拟相关温度，以评价采收率，提高热采油的热效率。本文系统地回顾了一些经典的和先进的井筒、地层和储层传热分析模型，并详细介绍了传热分析的建模原理。在研究井筒稳定换热和地层瞬态热传导的基础上，综述了几种井筒流体温度模型，总结了一些储层温度分布和热效率的解析解，并进行了详细的比较。此外，对热采油分析传热方法的关键问题进行了总结和讨论。最后，对热采油传热分析的未来发展和应用进行了展望。
Thermal recovery perhaps is the most significant method for enhanced oil recovery (EOR) technique, especially for heavy oil production, which is defined as a progress in which thermal energy is introduced into the subsurface of reservoir for recovering fuels. Study on thermal energy transporting in oil well dominates the application of thermal recovery process. Predictions of the field behavior of the process require an accurate accounting of the thermal energy injected in to reservoir, therefore a number of heat transport analysis work for wellbore, formation and reservoir have been developed to simulate the related temperature for evaluating oil recovery efficiency and improving thermal efficiency of thermal oil recovery. In this paper, some classical and advanced analytical heat transfer models for wellbore, formation and reservoir are reviewed systematically, and the modeling principles for the heat transfer analysis are also introduced in detail. Based on investigation of steady heat transfer of wellbore and formation transient heat conduction, several wellbore fluid temperature models are reviewed, and some analytical solutions for reservoir temperature distribution and thermal efficiency are also summarized with a detailed comparison. Moreover, the summary of key problems for analytical heat transfer method for thermal oil recovery are described and discussed. Finally, the future development and application of heat transfer analysis for thermal oil recovery is also proposed.
