| 摘 要： | 针对海上特稠油油田复杂油水界面在地质建模及数值模拟过程中的表征，提出一种非平衡输入建立饱和度场的等效方法。该方法通过油水界面三维分布模拟、油水分区属性场构建及含水饱和度模拟等构建准确表征复杂油水分布特征的含水饱和度场，利用该含水饱和度场替代油水界面，实现地质模型中储量拟合及油藏数值模拟模型中复杂油水界面的定义。在渤海LD油田，利用该方法解决了地质建模及数值模拟过程中复杂油水界面表征难题，为油田开发方案研究奠定了模型基础，同时也可为其他类似油田研究提供借鉴。

| Abstract: | A method to better identify the complicated oil/water interface in geological modeling and reservoir numerical simulation is proposed in this paper for extremely heavy oil. Via the simulation of 3d distribution of oil/water interface, the construction of oil/water partition property field and the simulation of water saturation, a final water saturation model is constructed, which can accurately define the complicated oil and water distribution pattern. The definition of complex oil/water interface in reserve fitting and reservoir numerical simulation may be realized by using the final water saturation model instead of oil/water interface. In the LD oil field, the complex problem of oil/water interface presentation was solved by using the method in geological modeling and numerical simulation for oilfield development planning. It can also provide a reference for other similar oilfields. |
