超压传递:概念和方式

OVERPRESSURE TRANSFERENCE: CONCEPT AND WAYS

在超压沉积盆地中,超压传递可能是一种较普遍的现象。超压传递是由超压系统释放或泄漏出的超压流体的流动而引起其他压力系统孔隙流体压力增加的作用。根据超压传递的指向,可分为横向传递和垂向传递两类。由超压传递形成的超压称为传递超压。超压传递的作用方式包括超压流体的注入作用、超压流体沿渗透性砂体的运移作用和超压封存箱的膨胀作用。文中还讨论了东营凹陷的超压传递现象。

Overpressure transference may be a kind of widespread phenomenon in overpressure sedimentary basins. Overpressure transference is the increasing of porefluid pressure in other pressure systems caused by the flow of overpressure fluid released or leaked from overpressure systems. Base on the orientation of overpressure transference, vertical and lateral two types of overpressure transference were divided. The overpressure resulting from overpressure transference was named transference overpressure. The ways of overpressure transference include the injection of overpressure fluid, the migration of overpressure fluid along permeable sandbodies and the dilatation of overpressure compartments.
