多级相控建模在B区块的应用

Application of multi-phase control modeling in B block

随着对油藏模型精确度要求的不断提高,运用可掌控的约束条件,在常规建模流程的基础上,采用多级相控建模技术,以储层地质数据库为基础,建立沉积微相模型。在其严格约束下,采用序贯指示算法建立岩相模型,再用优选出的岩相模型约束,建立储层属性模型。多级相控建模技术,提高建模精度,减少随机建模的不确定性,较精准地刻画储层砂体内部非均质性,为油藏开发方案设计提供更好的地质模型,实现井间储层多学科一体化、三维定量化及可视化预测[1]。

With the continuous improvement of the accuracy requirements of the reservoir model,using the controlledconstraints,based on the conventional modeling procedure,using multi-phase controlled modeling technology,we establish thesedimentary microfacies model based on reservoir geological database. In the strict constraints,we establish rock facies model usingsequential indicator algorithm,then,under the constraints of the optimized rock facies model,we establish reservoir propertymodels. The technology of the multi-phase control modeling improves the modeling accuracy,reduces the uncertainty of the randommodeling,more precisely describes the reservoir sand body heterogeneity,provides the geological model for the scheme design ofreservoir development,realizes the prediction of the multi discipline integration,3D quantification,visualization of reservoir interwell.
