| 摘 要： | 提出用布尔模拟与模拟退火结合的两阶段模拟方法模拟井间储层参数分布。第一阶段 ,利用布尔模拟方法模拟出井间的砂、泥岩分布 ;第二阶段 ,在布尔模拟结果的基础上 ,用模拟退火方法模拟井间储层参数的分布 ,退火时依据不同的岩性特征 ,分别建立各种岩性所对应的条件直方图和变异函数 ,使岩性对参数分布的控制作用真正得到了体现。研究中很好地解决了布尔模拟与模拟退火之间的耦合问题 ,可以直接应用布尔模拟的结果来指导井间储层参数分布的预测。实际应用效果表明 ,该方法模拟结果具有一定的准确性和可信性

| Abstract: | A two?_stage simulation method can be used in simulating the distribution of interwell reservoir parameters. At the first stage, the Boolean simulation method is adopted to establish the model of interwell sandstone and shale distribution, and at the second stage, the simulated annealing method is applied to characterize the distribution of interwell reservoir parameters on the basis of the model.The problem of linkage between the Boolean simulation and the simulated anneal has been satisfactorily solved in this paper, and the results of the Boolean simulation can be directly used to guide the prediction of interwell reservoir parameter distribution. A case study was given in this paper and the results show that this simulation method is quite accurate and reliable. |
