摘　　要：文南油田文33断块地质条件复杂,现有的三维地质模型已不能满足其开发的需要,需建立新的地质模型。针对此问题,综合利用研究区的地质、测井资料,采用隔夹层模型与沉积相模型镶嵌的方法,分别建立不同级次的隔夹层模型和单砂层沉积相模型,并以构型模型为约束条件建立属性模型。所建立的构型模型能够反映储层外部形态(微构造)和内部成因差异(沉积微相),构型模型约束下的属性模型能反映不同相带下的储层物性变化特征。Due to the complex geological conditions of Wen33 fault block in Wennan Oilfield,the existing 3D geological model cannot meet the development needs and a new geological model is needed.Based on the comprehensive geological and logging data of the study area,the models of interlayer and single sand layer sedimentation of different grades are established respectively,with the mosaic method of inlaying interlayer model and sedimentary facies model.Finally,the attribute model is established with architecture model as constraint.The results show that the model can not only reflect the external morphology(microstructure)of the reservoir,but also reflect the internal genetic differences(sedimentary microfacies).The attribute model under the constraint of the model can reflect the change physical characteristics of the reservoir in different facies zones.
