Abstract: A simulation method of facies-controlling parameter field was proposed to predict the planar distribution of reservoir property parameters.The basic simulation principles of facies-controlling parameter field were studied. In the complete consideration of influence of sedimentary microfacies on reservoir property parameters,the simulation method of sedimentary microfacies was applied to the simulation of reservoir property parameter field.The linkage of sedimentary microfacies simulation and sequential gaussian simulation has been satisfactorily realized.The simulation result of sedimentary microfacies model can be directly used to control the distribution of reservoir property parameters.Consequently,an idea of microfacies controlling parameters is realized.The application results show that this method is prior to Krigging method in prediction of heterogeneous characters of reservoir planar parameters.

摘要： 提出了采用相控参数场方法模拟储层参数平面分布的方法,探讨了相控参数场的基本原理。在充分考虑沉积微相的基础上,利用沉积微相的模拟结果进行参数场的模拟,解决了沉积微相模拟与序贯高斯模拟之间的耦合问题,可以直接应用微相模拟的结果来处理储层参数的分布问题,充分利用了微相对参数分布的控制作用。实际应用结果表明,该方法的模拟结果在预测储层平面非均质性方面大大优于克里格估计。
