【摘要】 对致密砂岩而言,确定优质储层和有效砂体的展布规律是气田开发的关键;而储层地质建模可从三维角度直观地实现储层精细描述,在油气田开发中得以广泛应用。在地震、测井、测试、钻井等各方面的资料基础上,遵循从点-面-体的步骤建立了鄂尔多斯盆地苏里格气田ZT1示范区的构造模型、沉积相模型和储层属性模型。构造模型描述了研究区北东高而南西低的西倾单斜构造的空间格架;沉积相模型展示了研究区盒8段辫状河三角洲平原和山1段曲流河三角洲平原的沉积相展布特征;属性模型直观地展示了研究区的低孔、低渗的物性特征。更多还原

【Abstract】 It is a keystone of gas field development to confirm the distribution of high quality reservoir and effective sand bodies in tight sandstone gas field.Geological modeling is extensively used in gas field development for accurate and intuitive description of the space frame and geometry of tight sandstone reservoirs.This study taking advantage of seismic,well logging,testing and drilling data established the tectonic model,sedimentary facies model and reservoir model in the ZT1 demonstration area of eastern Sulige Gas field in the Ordos basin with 3D perspective,following the steps of point-face-body.The tectonic model describes the space frame of west dip monoclinal structure,high in northeast and low in southwest in the study area.The sedimentary facies model shows that the He 8 section develops braided river delta plain subfacies and Shan 1 section mainly develops meandering river delta plain subfacies respectively.The attribute model has intuitive expression of physical characteristics with low porosity and low permeability in the study area.更多还原
