摘　　要：陆相断陷盆地是中国东部盆地的重要类型,在我国石油勘探开发领域中占有重要地位。深层广泛发育的异常流体压力和复杂断裂系统是2个重要特征,研究两者的相互作用有助于更加科学、有效地进行油气运移、聚集研究。在综合分析陆相断陷盆地流体压力和断裂特征的基础上,以济阳坳陷东营凹陷为典型例证,充分应用钻、测井资料,建立了高精度的凹陷异常压力分布模型;结合断裂系统特征,探讨了在三级构造单元格架下,流体压力与断裂系统在空间上的配置关系以及断裂系统对流体压力纵横向分布及封闭特征的影响。Continental fault basin is an important basin type in the east of China, and is significant for oil exploration and production. It is characterized by abnormal fluid pressure extensively formed in deep formation and complex fault system. Study of the mutual action of these two characteristics is helpful for the analysis of oil migration and accumulation. Based on the analysis of fluid pressure and fault characteristics of continental fault basin, a precise model of abnormal pressure distribution in sag is made. It is also discussed in this paper the spatial relationship between fluid pressure and fault system and the influence of fault system on vertical distribution of fluid pressure as well as the sealing characteristics.
