东营凹陷油气运移的地震泵作用
|
摘要
断层活动对烃类的运移有重要的影响作用。岩石中微裂隙→裂缝→断层的动态发育过程，生动地体现了地震泵运移机制周期性、间歇状脉冲的特点。这是由地质历史时期地震活动的周期性和变化的应力场中裂隙引张的间歇性、脉动性的特点所决定的。东营凹陷复杂断块油气田中独特的油气纵向分布特征，是由构造活动平静时期的渗流运移和构造活动活跃期中地震泵作用的混相涌流方式相互交替、共同叠加的结果，这一现象在各大油气田中较为常见，是一个较为普遍的规律。
Fault activities have important effects on hydrocarbon migration. The evolution process from microfracture→fracture→fault shows vividly the characteristics of periedic and intendttent pulse under the seismic pumping migrationmechanism,which were determined by the periodic seismic activities and intermittent pulse of fracture extension ofstress field chang in geological history. The unique venical distribution of the complex fault block oilfields in DongyingDepression is the result of altemation of transfusion during tectonic inactivity and seismic pumping during tectionic activity. This phenomenon is common in big oil-gas fields.
