随机模拟技术在彩10区块油藏描述中的应用

Application of Stochastic Simulation in the Reservoir Description of the 10th Wellblock of Cainan Oilfield

提出根据测井解释成果,结合对油藏沉积原模式的分析,应用截断高斯模拟方法定量地开展沉积微相的研究;然后应用沉积微相约束测井储层参数的分布,应用序贯高斯模拟方法建立储层参数模型。应用与该方法相适应的平方平均值的平方根(root mean square,RMS)软件成功实现了彩10井区的沉积微相模型和储层参数模型。

The geological modeling with sedimentary microfacies form is proceeding at the base of the Truncated Gaussian Fields modeling method. Applying the sedimentary microfacies form research can produce rather exact geological model which reservoir simulation need and solve the disfigurement which sedimentary research outcome disconnect with reservoir parameter distribution. The Sequential Gaussian simulation is choosed to model the facies model of the interest region. Applying RMS software being on speaking terms with the method realize successfully the exact sedimentary microfacies of Cai10 Block oilfield in sinking municipality.
