| 摘 要： | 流体势场是控制油气二次运移的主要因素。根据网格化的流体势数据,采用基于数字高程模型的剖面识别与多边形除边脊线识别算法(PPA),可以自动地识别出流体势场中的油气运移分隔槽。在此基础上可进一步划分出油气运聚单元或含油气系统,从而为利用网格化的数值模拟结果计算不同油气运聚单元内的油气资源量提供了一种有效的方法。通过在吐鲁番—哈密盆地台北凹陷三间房组的应用,自动划分的分隔槽比人工划分的分隔槽更精细,位置更准确。

| Abstract: | Fluid potential was a main control for petroleum migration. The compartition troughs could be recognized automatically from grid data in the fluid potential field by means of a profile recognition and polygon\|breaking algorithm (PPA), which was an algorithm to find the ridges from Digital Elevation Model in geography. The petroleum accumulation units and petroleum systems could be delineated from the layout of compartition troughs, further more, the petroleum resources in different units could be calculated based upon the grid data calculated from simulation taking the troughs as boundaries of different units. The application to the Taibei Depression in Turpan\|Hami Basin showed that the positions of troughs recognized by PPA were more precise compared with those plotted manually. |
