摘　　要：使用双Lelel set方法来重新表示油藏模型特征,渗透率可以通过解无限制的Lagrangian最优化问题得到.对Lagrangian范函加上Level Set函数的限制之后,鞍点就可以通过算子分裂格式得到.数值模拟表明新算法是稳定高效的.In this paper, bilinear level set method was used to represent the characterization of reservoir model. The permeability estimation can be solved by the augmented Lagrangian optimization method. After adding the constraint function to the augmented Lagrangian optimization functional, the saddle point can be found by operator splitting scheme based on the essence of binary level set method. Numerical Shows the algorithm stability and efficiency.
