Among them, one of the most promising seems to be Simulation Annealing that aims to reach the optimization of an objective function by physically analogizing to an annealing process of malerial at high temperature.

为此，目前主要采用三种基于随机搜索策略的鲁棒技术，其中模拟退火算法是最有希望的一种，该算法的核心思想是随机模拟物理上的物质退火过程，它主要涉及将连续域优化问题转换为离散的组合优化问题，以及合理地选择各种控制参数、迭代时间等。

According to the geological property of the research area, we apply sequence indicator simulation method if the reservoir type is discrete variable. Sequence Gauss simulation method is used if the type of reservoir property is continuous variable. Structural model (single well model, fault model and bedding model) and property model are built. The 3D distributions of reservoir parameters are established based on structural model. Three advantage oil distribution of the oil field are pointed out through overlap of the reservoir parameters distributions.
