贝叶斯序贯高斯模拟方法

各种静态数据约束下的三维储层模型是指可以同时满足地震和测井数据的模型。研究了整合中等垂向分辨率地震数据的方法。引入贝叶斯定理的序贯高斯模拟方法,即贝叶斯序贯高斯模拟,用来整合中等垂向分辨率的地震数据,在给定地震频率的条件下,提高模型的分辨率。模拟结果表明,该方法能很好地整合中等垂向分辨率的地震数据,解决整合地震和测井数据存在的“体支撑”难题,生成高于地震垂向分辨率、低于或等于测井分辨率的三维储层模型。

Bayesian sequential Gaussian simulation method

The models constrained by many kinds of static data are representative as the models constrained by seismic data and well log data.The methods used to integrate seismic data of intermediate vertical resolution were studied.Sequential Gaussian simulation with Bayesian upgrading can be used to incorporate seismic data of intermediate vertical resolution into 3-dimensional reservoir models.Given a specific seismic frequency,the resolution of model by this method can be improved.The results of model show that the volume support problem can be addressed,and generate a model whose vertical resolution is higher than that of seismic data and lower than or equal to that of well log data by this method.
