摘　　要：区域分解算法在油藏数值模拟中的应用已得到了国内外学者的共识,然而,该方法在热采数值模型中的应用极少。根据热来模型的多相、多组分的特点,构造了适合全隐式计算方法的区域分解算法,并给出详细的实现步骤和区域收敛的判断条件。实例计算对比表明:区域分解算法适用于热采模型,带有区域分解算法的热采模型与常规热来模型的计算结果吻合很好,计算结果是可信的;使用区域分解算法可进一步提高热采模型的计算速度,节省计算时间。图4参4（吴淑红摘）Many reservoir engineers have known the importance of domain decomposition method in numerical reservoir simulation, but its application in thermal simulation is seldom. In this paper the probe study was made on the application of the method in thermal simulation. Based on the multi-phase, multi-component of thermal simulation, the domain decomposition method suitable to fully implicit solution method was derived. Finally, the comparison between the thermal simulation with and without domain decomposition method was carried out. The result shows that the application of domain decomposition method in thermal simulation is successful and its calculation result is believable; application of domain decomposition method can increase calculation speed and decrease the CPU time.
