| 摘 要： | 油气在输导中运移聚集的路径主要取决于封盖面的状态、砂体的分布及横向封堵面，位于与油源相接的汇聚路径上的圈闭有利于捕集到油气，发散路径导致油气的散失。在地史、生排烃史计算的基础上，利用计算机来恢复地质历史时期封盖面的空间几何形态，并识别分析运移路径的性质，模拟不同时期油气的运移方向和强度，并最终计算圈闭聚集量，指出油气聚集的有利区带，对指导油气勘探具有现实意义。在辽河滩海地萄应用验证了现有勘探成果,并提出了下一步勘探方向。

| Abstract: | Pathway of hydrocarbon migration and accumulation is controlled by sealing surface,sandstone distribution and lateral change of porous layer.It is favorable for hydrocarbon accumulation that the trap is located on a focus pathway connected to area of hydrocarbon generation.Based on structural deformation,hydrocarbon generation and expulsion simulation,we can rebuild the three dimensional shape of sealing surface in the period of geological history in virtue of computer,analyze and recognize pathway of migration,simulate direction and intensity of hydrocarbon migration in different periods,calculate accumulation quantity of traps,and indicate favorable region.It is useful to guide oil exploration.The simulation technology applied to the beach of Liaohe Oilfield,shows that exploration results well tally with simulation. |
