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.
The dual Lelel set method is used to re-express the characteristics of the reservoir model, and the permeability can be obtained by solving the Lagrangian optimization problem without constraint. After adding the limit of the Level Set function to the Lagrangian normal function, the saddle point can be obtained by the operator split form. Numerical simulation shows that the new algorithm is stable and efficient.
