摘　　要：注蒸汽热采稠油是一个带有相变的多孔介质中多相流动问题。利用自适应网格法动态追踪油藏中的温度和饱和度锋面,以大幅度提高计算速度。在对渗透率空间分布不均匀、油藏区域分布不同种类输运性质岩石、裂缝-孔隙双重介质、非规则边界及内部含有断层油藏等复杂地层注蒸汽热采稠油问题开展自适应网格法的研究基础上,自主开发了注蒸汽热采稠油油藏数值模拟自适应网格法计算软件。该软件具有较高的计算精度和稳定性,可满足科研生产需求。Thermal recovery of heavy crude oil by steam injection is a multi-phase flow problem in porous media with phase-change Adap- tive mesh refinement （AMR） technique is applied in the article to dynamically track the temperature and the saturations fronts in reservoir in order to significantly improve the computation speed. An AMR software package for reservoir numerical simulation in thermal recovery of heavy crude oil by steam injection has been developed independently, which is on the basis of studying the employment of AMR on the issue of thermal recovery of heavy crude oil by steam injection in complex strata such as the permeability spatial variations, the distribution of rock- types in different transport properties in reservoir region, the fractured-porous dual media, the irregular boundary as well as the interior faulted reservoir, etc. This software package has preferable computation precision and numencal stability to meet the demands of scientific and engi- neering research.
