摘　　要：根据潜山油藏岩性分布复杂、非均质性强的特点,提出了变质岩潜山油藏相控建模方法,即依据"优势岩性"理论,利用录井资料中的岩性分析数据,建立变质岩相分布模型;以变质岩相为约束条件进行储层建模,实现了相控条件下基质的孔渗模拟。针对该类油藏裂缝发育、存在裂缝渗透率各向异性的特点,将各向异性建模方法引入潜山裂缝性油藏建模中,建立裂缝渗透率各向异性的定量表征模型。该方法考虑了裂缝和基质渗流特征,建立了双重介质模型,更便于与油藏数值模拟结合应用。Proceed with the characteristics of complex lithology and strong heterogeneity for buried hill reservoir,this paper proposed the method of facies controlled modeling for buried hill reservoir with metamorphic rock.The distribution model was established based on the advantage lithology theory and using the analysis data in logging information.The porosity and permeability of matrix was simulated under the facies-controlling condition.Aimed at the characteristics of fracture development and fracture permeability anisotropy for this kind of reservoir,the anisotropy modeling method was introduced to the modeling of fractured buried hill reservoir and the quantitative representation model of permeability anisotropy was established.Taking into account the difference of permeability between matrix and fracture,the aim of this method is to establish dual porosity model,which can be easily used in reservoir simulation.
