摘　　要：流体封存箱理论来源于勘探实践并服务于勘探实践，将油气的生、运、聚纳入统一的时空体系进行研究，是新兴的石油地质学理论之一。通过分析得出的结论是：流体封存箱存在于具有异常压力的盆地中，它是否存在与盆地类型及沉积速度无关；流体封存箱顶板一般位于３ｋｍ深度，是盆地沉积物压实—水力压裂—胶结的结果；断层通过热液胶结作用或差异压实胶结作用，起到封存箱边板的作用；流体封存箱理论并没有违背流体动力学的基本原理；封存箱内压力的动态演化过程中的量变与质变，决定了压力随时间调整的方式。图４参１３（王孝陵摘）As a new petroleum geology theory, the theory of abnormally pressured compartment integrate the generation, migration and accumulation of oil and gas into one temporal and spatial system. The theory comes from and serves to the petroleum exploration. According to analysis, the following conclusions can be drawn: fluid compartment exists in the basins with abnormal pressure, regardless of the typed and sedimentation rate of basins; the top seal at the depth of about 3km is the result of compaction hydrofrac cementation; faults serves as side seals through hot fluid cementation or differential compaction cementation; fluid compartment does not disobey the basic rule of fluid dynamics; the two types of pressure adjustment depend on the quantitative and qualitative changes of the pressure during its dynamic evolution in the compartment.
