摘　　要：准噶尔盆地台13井区侏罗系八道湾组为辫状河沉积,河道砂体横向分布不稳定。本区波阻抗与沉积相间有很好的概率相关关系,因此提出一种以测井约束波阻抗反演数据体为约束条件,结合储层地质建模技术,对该区辫状河储集层进行三维地质建模的方法。优选出该区储集层岩相和属性建模的最佳方法分别是序贯指示模拟和序贯高斯模拟。建立的该区八道湾组地质模型能很好地反应地下地质体,为八道湾组油藏开发奠定了基础。The sedimentary environment of the Jurassic Badaowan formation in T13 zone in Junggar Basin features braided rivers. In this area, the sand in the stream channel varies greatly in transverse directions. The acoustic impedance and sedimentary facies have a good probabilistic dependency according to research, so a 3D logging-constrained inversion dataset is used as the constraintcondition. Geological modeling techniques are adopted to make an accurate estimation of the geological modeling of fluvial reservoir. Indicator simulation is the best method to model the sedimentary micro-facies, and sequential Gauss simulation gives the best results for attribute modeling. The modeling results are in agreement with the overall features of the subsurface geology and provide a good foundation for exploiting the Badaowan formation reservoir.
