东营凹陷油气运聚古地下水动力场剖面数值模拟

Numerical simulation for the section of palaeogroundwater hydrodynamical field during migration and accululation of oil and gas in Dongying depression

本文对东营凹陷油气运聚古地下水动力场剖面数学模型的建立、古水文地质参数的再造、模拟初始值的恢复进行了阐述。在此基础上，进行了东营凹陷油气运聚古地下水动力场剖面数值模拟。模拟结果与已知油田的分布具有较好的一致性。推断的东营凹陷油气聚集有利地段，可以作东营凹陷油气田进一步勘探开发的依据。

The setablishment of mathmatical model of palaeogroundwater hydrodynamical field and the reconstruction of palaeohydrogeogical parameters and simuiation original value for Dongying are described in the paper.Based on above is given the numerical simulation for the section of Palaeogroundwater hydrodynamical field during migration and accululation of oil and gas in the depression.The result of simulation is well consistent with the distrabution of known oil fields.The predicted area for accumulation of oil and gas in Dongying Depression may be prospected and exploited in future as a result.
