摘要:
点坝是渤海湾盆地的重要储油单元,随着油田开发进入高含水阶段,点坝内部构型对油水运动和剩余油分布的影响愈加显著,挖潜难度逐步提高。海上油田由于井距大,井间对比难以实现侧积层刻画。为解决这一问题,提高地质模型精度,提出了基于曲流河演化模拟、井数据拟合的点坝内部构型建模新方法。该方法通过曲流河演化模拟获取具有真实形态特征的点坝三维构型初始模型,并通过搜索域与逻辑筛选的方式实现与井数据的拟合,从而实现点坝内部构型的三维建模。这一方法应用于渤海湾盆地A油田曲流河相储层点坝内部构型建模,结果显示,该方法不仅能够构建具有真实形态的构型模型,同时能够忠实于井数据,为点坝内部构型精细研究提供了一套新的思路与方法。
Abstract:
Point bar is one of important oil units in Bohai Bay Basin. As the oilfield development entered the high water stage, the internal architecture of point bar has more and more significant effects on oil-water movement and oil remaining distribution, and the difficulty in tapping the potential is gradually increased. However, due to limited to large well-spacing in offshore oilfields, the lateral accretion layers are hardly depicted by the well-to-well correlation. To solve this problem and improve the precision of geologic model, it was proposed a new modeling method for the internal architecture of point bar based on evolution simulation of meandering river and well data fitting. Based on the evolution simulation of meandering river, it is obtained real morphological characteristics of initial model of 3D point bar architecture. And then the well data fitting is realized by the means of searching domain and logical judgment. So it is obtained the 3D modeling of internal architecture of point bar. This method was applied for modeling the internal architecture of point bar of meandering river facies reservoirs in A Oilfield of Bohai Bay Basin. The application results showed that the method can be used to not only model the real morphology of architecture, but also agree with actual well data, providing a set of new idea and method for studying on fine depiction of the internal architecture of point bar.
