摘　　要：为提高苏里格气田苏西区盒8段气藏的开发效率,综合运用测井、录井、岩心、压汞等资料,重点研究该区水平井资料,明确了苏西区盒8段沉积相、储层空间分布规律。结合地质认识,采用井点约束、横向属性概率约束、相控约束、协同模拟约束多种约束方法,对变差函数特征值进行优选与调整,建模结果显示,多约束条件的粗化数据结合序贯模拟方法能够建立较为准确的岩相模型与物性模型,实现储层参数的定量化,为寻找优质储层以及甜点区提供依据。In order to improve the development efficiency of He 8 gas reservoir in Suxi area of Sulige gasfield,the spatial distribution laws of the sedimentary facies and reservoir of the He 8 member were determined according to the comprehensive analysis of well logging,mud logging,core,mercury pressure and other data of horizontal wells in the area.Combined with geological knowledge,the characteristic values of variogram are optimized using the multiple constraint methods such as wellpoint constraint,lateral attribute probability constraint,facies constraint,collaborative simulation constraint.The modeling result shows thatthe modeling results show that to use the coarsening data with multiple constraints and sequential simulation method can establish a more accurate lithofacies model and physical property model so as to realize the quantification of reservoir parameters and provide a basis for finding high-quality reservoirsand dessert areas.
