EnKF assimilation of simulated spaceborne Doppler observations of vertical velocity: impact on the simulation of a supercell thunderstorm and implications for model-based retrievals
EnKF velocity

Recently, a number of investigations have been made that point to the robust effectiveness of the Ensemble Kalman Filter (EnKF) in convective-scale data assimilation. These studies have focused on the...
EnKF整合三维地震数据和动态数据的应用
集合卡尔曼滤波 油藏描述 历史拟合
2009/11/5
主要介绍集合卡尔曼滤波EnKF在更新油藏储层静态参数方面的应用。根据集合卡尔曼滤波产生的必要条件，介绍了集合卡尔曼滤波整合动态数据和三维地震数据的基本原理。通过实例分析，验证了集合卡尔曼滤波在整合动态数据和三维地震数据更新油藏参数方面的有效性，更新后的油藏模型能够较好地反映储层非均质性，并且与三维地震数据有较好的一致性。还比较了利用三维地震数据和四维地震数据进行更新油藏模型的差别。通过EnKF方法...
