A Study on the Ancient Fluid Potential and the History of Oil-gas Migration and Accumulation in Banqiao Depression
-
摘要: 本文从板桥凹陷出发，以古流体势动态地描述了油气运移聚集史。建立和讨论了断层在古流体势数值模拟恢复中的处理方法，对有利油气勘探区进行了级别划分，并指出自生自储油气常分布于高势区域。阐明类似板桥凹陷的年青盆地具沉积压实离心流的特点，水流方向与各期流体势方向基本一致。最后作者预测出板桥凹陷一批有利的勘探区。Abstract: This paper deals with dynamicly the histrory of oil-gas migration and accumulation, especially in Banqiao Depression. In this paper we developed and discussed the processing methods of faults in the ancient fluid potential simulation, graded benefitial exploration areas, and pointed out that self-generated and self-reservoired oil and gas were usually located in high potential areas. Furthermore, It's illustrated that the younger basin, similar to Banqiao Depression, is the characteristic of sedimentry pressure centrafugal fluid, and the water moving direction is the same with that of fluid potential. At last, the authos predicted that there are series of hopeful areas distributed in Banqiao Depression.
