摘　　要：为准确预测鄂尔多斯盆地苏6加密试验区块盒8段有效储层的空间分布，利用苏6加密试验区块的地质、测井和生产动态资料，建立了包括地层格架、构造、沉积和储层属性等子模型在内的储层地质模型。研究表明，苏6加密试验区块盒8段为河流相沉积环境，储层砂体的成因类型包括点坝、心滩、河道等，呈南北向带状展布，横向尖灭快。储层孔隙度分布范围为3％～15％，渗透率为（0．1～2）×10^-3μm^2，是典型的低孔低渗储层，储层非均质性强。应用储层地质模型，可以直接预测有效储层的空间分布，为气田开发井网的部署和调整提供地质依据。In order to predict the effective reservoir sandstone distribution of He8 Member, Su6 infilling well experimental area, Ordos basin, a reservoir geological model is built with the geological, logging and production data, including 4 submodels （formation skeleton model, structure model, sedimentation model and property model）. According to the geological model, the depositional environment of He8 Member, Su6 infilling well experimental area is fluvial facies, nel, point bar and channel bar. The sandstone with the sandstone microfacies, which is composed of chanlace shape extends from north to south. The reservoir with porosity 3%--15% and permeability （0.1-2）× 10^3μm^2 is typically low-porosity and low-permeability. Using the geological model, the space distribution of the effective sandstone of the experiment area can be predicted directly and accordingly provides the geological basis for the gas field development.
