| 摘 要： | 根据地质、地球物理资料,对惠民凹陷的地层层序、构造一岩石组合、基底和盖层构造特征、成因和演化历史及其与油气关系等进行了系统研究,将惠民凹陷的演化划分为断陷期(E)和坳陷期(N—Q).前者包括断陷早期(E_k。)、断陷早中期(Es_4)、断陷中晚期(Es_(2 3))和断陷晚期(Es_1—Ed).计算结果表明,凹陷的最大拉张量为24.1％.根据区域地质研究结果预测,阳信洼陷北部和南部,临南洼陷和南缘斜坡具备潜在油气圈闭条件,可作为新的勘探目标.

| Abstract: | The characteristics of stratigraphic sequences, petrological assemblages, basement and cover structures, the origin and evolution of the Huimin sag a secondary structural unit of the Jiyang depression and their relations to hydrocarbon traps are sysmatically studied on the basis of geological and geophysical data. The stress field of the Jiyang depression is unified with that of the Talu fault system. The evolution of the Huimin sag was divided into two major stages: fault depression (E) and depression (N-Q). Calculation showed that the maximum extensional amount is 24.1%. Regional geological study revealed that the sub-sag may possess thick source beds and higher geothermal gradients. The Linnan sub-sag and the slope of the southern margin could also be a target for exploration. |
