摘　　要：鄂尔多斯盆地DS气田J58井区下石盒子组气藏为典型致密岩性气藏,储层非均质性强,砂体多为纵向多期叠置且横向变化快,制约了高质量水平井的部署。综合运用地质认识、测井数据、物探层位数据及地层对比,建立J58井区三维构造模型;以地震振幅平面属性为软约束和单井数据为硬约束条件,建立工区下石盒子组三维岩相模型,为井位部署及开发方案编制提供技术支撑。A typical tight sandstone gas reservoir is developed in The Lower Shihezi Formation of the J58 well block,DS gas filed,Ordos Basin,the reservoir has a strong heterogeneity,the sand body is multi-stage superimposed in the vertical and changes rapidly in the lateral,it restricts the deployment of high-quality Horizontal Wells.Based on the geological information,logging data,seismic horizon data and stratigraphic correlation,a three-dimensional structural model of J58 well blofdck is established.Taking the seismic amplitude attribute as the soft constraint and the well data as the hard constraint,the threedimensional lithofacies model of The Lower Shihezi formation in the work area is established to provide technical support for the well deployment and the development plan.
