This makes more and more people pay more attention to studies and applications of numerical simulation in thermal recovery. In this research, we have developed a reliable mathematical model for thermal recovery, which takes a full consideration of the effect of viscos, gravitical and capillary forces on the three-phase flow of gas, water and oil, the effect of the temperature on the medium characteristics of liquid and solid, the phase equilibrium of gas-liquid in each component, heat transportation including connection, conduction and radiation as well as heat losses in both the overburn and underlying strata. In the space discreation of the mathematical model, we have proposed a new method based on the improvement of the conventional nine-points difference approximation, which has a higher difference accurancy.

本项研究以热力采油的主要机理为基础，充分考虑在粘性力、重力和毛管力作用下油水气三相流动，考虑温度对各种流体和固体介质物性的影响，考虑每一组分中汽液两相的相平衡，考虑热在地层中的传导、对流和辐射以及上下盖层的热损失，利用热力学第一定律、质量守恒定律和流体迁移定律，建立了正确可靠的注蒸汽数学模型；在对数学模型进行空间离散时，利用控制有限体积积分法，对以往的九点差分近似作了合理的改进，使其具有较高的差分近似精度：结果表明，该公式的近似精度要比以往文献中所给的九点差分近似精度高，可以认为，在油藏数值模拟中，如果遇到非均质情况，使用这种九点差分近似更合理。

At the same time, in the transmission system of construction machinery up-to-date, the power transferred by the transmission is improved greatly, while the gear friction is adopted in the transfer structure, so the heat loss will influence both the lubrication and cooling of the system, and the working intensity of the structure components. Therefore, the correction of the heat balance is necessary to the system.

同时，在现代工程机械的变速传动系统中，由于行星变速箱所传递的功率有了大幅的提高，但传递结构依然大量采用齿轮摩擦传动，其热损失不仅对系统的润滑和冷却有影响，而且对结构元件的工作强度也具有很大的影响，因此，也需要对该系统进行热平衡校核。

The main reasons for the higher efficiency are the elimination of the water pump, the elimination of the water heat exchanger (which is a source of heat losses), and the phase change of the refrigerant in the ground itself, allowing a higher temperature gradient between loop and ground resulting in a higher rate of heat transfer.

为高效率的主要原因是水的泵，水的热交换（这是一个消除热损失的来源），以及本身在地面制冷剂相变，从而使一回路和地面之间的热传递率较高导致较高的温度梯度。
