特低渗油田储层宏观非均质性研究

Research on Macroscopic Heterogeneities of Ultra-low Permeability Reservoir

储层宏观非均质性研究是进行油藏描述时重要的工作,特别是对特低渗油田的开发有着重要的意义。通过对鄂尔多斯盆地某油田延长组长6储层的层内非均质性、层间非均质性和平面非均质性三个方面的分析研究,对储层宏观非均质性的分析方法进行了阐述。

Research on macro heterogeneity of reservoirs is an important job in reservoir description,especially development of the ultra-low permeability reservoir.Based on analysis and study of in-layer heterogeneity,interlayer heterogeneity and plane heterogeneity of one oilfield in Ordos basin,analysis methods for macro heterogeneity of reservoir were discussed.
