摘　　要：含油气盆地的异常流体压力是油气运移研究中的重点。近年来 ,压力封存箱概念的提出和应用 ,对建立以压力封存箱为核心的三维压力系统模式具有重要意义。异常流体压力的形成机理可归纳为与应力有关的作用、新生流体源的生成、流体的运动等三方面。如果沉积盆地是一个大型化学反应器 ,烃类的形成、幕式排烃、油气运移动力等将是近期研究的主要方向。文章归纳总结了计算异常流体压力的主要方法 ,包括等效深度法、地层因子法及菲利朋法等 ,并首次应用地层因子法对济阳坳陷东营凹陷进行了地层压力的计算 ,与等效深度法相比 ,其计算精度和计算的稳定性都有很大提高。Anomalous fluid pressure in oil?and?gas bearing basin is the focal point in the study of oil and gas migration. In recent years the presentation and application of concept of pressure compartment has important significance for building 3D pressure system model taking the compartment as center. The forming mechanism of the anomalous fluid pressure can be summed up as three aspects: effect related to stress, generation of new fluid source, and fluid movement. If sedimentary basin is a large?scale chemical reactor, hydrocarbon generation, episodic hydrocarbon expulsion and dynamic force of oil?and?gas migration will be the main directions of recent research. The main methods of calculating the anomalous fluid pressure are summed up in this paper which include equivalent depth method, formation factor method, Fillippone method and so on. The formation factor method is used to calculate the formation pressure in Dongying sag of Jiyang depression firstly, which brings greater improvement on accuracy and stability in calculation compared with equivalent depth method.
