摘要: 油气二次运移的方式和方向对具体指出盆地油气资源量所赋存的位置有决定性的意义.在运载层中推动油气运动的作用力主要是浮力和毛细管力,而盖层则起着毛细管阻力作用.因此盖层的形状及空间分布就成了影响运移路径重要的封盖因素.该文试图根据盖层的几何形状特性,建立运移路径模拟模型,开发微机软件运行实施.在一个具体盆地进行运移路径模拟应用的结果反映,与已知勘探情况基本符合,能够检验油气期次性运移的地质概念,可以揭示运移过程,预测可能的运移聚集位置.Abstract: The way and direction of secondary hydrocarbon migration are of decisive significance to concrete pointing out the occurrence location of hydrocarbon resources in basins. In delivery layers,the efforts driving hydrocarbon are mainly buoyancy and capillary force,and caprock plays an role of capillary resistance. Thus,the form and space distribution of caprock become important sealing factors to affect migration pathways. According to the geometric form features of caprock in this paper,the simulation models of migration pathways were established,and microcomputer softwares were developed and put into operation and enforcement. The application of migration pathway simulation to a basin reflected that it was in keeping with the known exploration situation on the whole. It can examine the geological concept of periodic hydrocarbon migration,reveal the process of migration,and predict the possible position of migration and accumulation.
