摘要

摘要: 通过研究盆地各压力系统(超压带、过渡带及常压带)油藏烃类地球化学特征的差异性，建立地球化学指标变化与动力学条件的关联。以渤海湾盆地济阳坳陷东营、沾化凹陷为例，分析甾烷异构化参数、轻/重比参数随深度的变化，明确由超压充注到常压驱动的过渡。选取东营凹陷博兴洼陷(单一压力结构)和沾化凹陷渤南洼陷(复合压力结构)的典型剖面，分析各区带地球化学参数差异性对应的动力学条件，各指标的变化与超压驱动及浮力驱动表现出良好的对应关系，并对成藏期异常压力的波及范围进行研究，该范围远大于现今油藏异常压力的分布范围，尤其在斜坡断阶带向外围有较大幅度延伸。在对动力条件进行地化表征的基础上，精细刻画成藏体系与供烃范围。

Abstract: In order to establish the relationship between hydrocarbon characteristic variations and dynamic environments, the differences of hydrocarbon geochemical characteristics of reservoirs in various pressure systems (overpressure zone, transitional pressure zone and normal pressure zone) were studied. The Dongying and Zhanhua sags in the Jiyang Depression of the Bohai Bay Basin were taken as examples in this paper, the variations of sterane isomerization parameter, sterane light/heavy ratio with depth were revealed. The transition from overpressure charging to normal pressure driving was clarified. The typical profiles of the Boxing (single pressure structure) and Bonan (composite pressure structure) sub-sags in the Dongying and Zhanhua sags, respectively, were selected for the differential analyses of geochemical parameters and corresponding dynamic conditions in various belts. The variations of the geochemical parameters showed high correlations to overpressure driving and buoyancy driving. The development ranges of abnormal pressure during reservoir formation were studied as well, which are much larger than the present abnormal pressure distribution ranges. Especially in the step-fault zone belt, historic overpressure had greatly extended outwards. According to the geochemical characterization of dynamic conditions, the reservoir formation systems and hydrocarbon supply ranges were described in detail.
