砂控约束条件下的多参数协同建模

以构造特征、砂体展布、测井解释等研究为基础,建立Y井区的构造模型和砂泥岩相模型,进一步采用砂控约束条件下的多参数协同建模.建立了该井区储层孔、渗属性横型及油水分布模型.并结合储层四性关系确定的储层物性下限标准建立了有效储层模型.通过模型检验证明了砂控建模的合理性,为后继的油藏数值模拟及方案调整提供了良好的三维储层模型.

Multi-parameter Collaborative Modeling Under the Constraint of Sand-controlled Environment

On the basis of structural features,sand body,log interpretation and other researches,the structural model and sand-shale facies model of Y well area were established,then through multi-parameter collaborative modeling under the constraint of sand-controlled environment,properties models of the reservoir were established,such as porosity model,penetration model and oil-water distribution model.Combined with the reservoir properties minimum standard which determined by four-property relationship of the reservoir,the effective reservoir model was built.By examining the model,it’s prove that the model established under the control of sand is reasonable,which can provide a fine 3D reservoir geologic model for the further reservoir numerical simulation and oilfield development program adjustment.
