介绍了随机模拟技术中模拟退火方法的一般原理。根据多井试井信息，应用模拟退火方法对渗透率的平面展布情况进行了模拟预测。利用模拟预测的结果可将地质认识的不确定性定量化，这样有利于研究和评价渗透率分布的随机性和不确定性，并可为未来生产动态等各种风险分析和决策提供可靠的依据。%Stochastic modeling is being increasingly used to generate the numerical models of reservoir parameters. The basic principle of simulated annealing method is described. The simulated annealing method is used to simulate the 2-D pemeability distribution from multi-well test information. The permeability simulation realizations provide a solid foundation for reservoir simulation, which is helpful to performance prediction and risk-conscious reservoir management.
