摘　　要：天然气运聚成藏过程模拟研究的发展与盆地模拟技术、含油气系统理论、油气成藏机理、成藏动力学、天然气聚散动平衡等研究的发展密切相关。结合中国大型气田的成藏特征,总结出前陆挤压多期充注、克拉通台地欠压缓慢聚气、克拉通挤压长期充注、裂陷张扭晚期充注、富盐盆地生物气高效充注等5种主要天然气运聚成藏模式。根据成藏规律、物理模拟实验、数学模拟等方面的研究现状和存在的问题,提出今后天然气运聚过程模拟研究应以时间要素研究为前提、以空间要素研究为基础、以动力要素研究为核心的研究方向。Development of simulation study of gas migration and accumulation processes is closely related with the advancement of basin modeling, theory of petroleum system, mechanism of reservoiring, dynamics of reservoiring and dynamic balance of gas accumulation and dissipation. According to the reservoiring characteristics of the large gas fields in China, 5 major gas migration and accumulation modes are summarized, including multi-stage gas charging in compressional foreland basin, slow gas accumulation in underpressured craton plateform, long-term gas charging in compressional craton, late gas charging in transtensional faulted depression, and highly effective charging of biogas in salt-rich basin. According to the status of the research and the existing problems in respects of reservoiring pattern, physical simulated experiment and mathematical simulation, it is proposed that future simulation study of gas migration and accumulation process should take the time element as the precondition, the space element as the basis, and dynamic element as the focus.
