摘　　要：元坝地区须二气藏属于典型的致密砂岩储层,孔隙结构复杂、储层物性差、非均质性强,通过对岩心资料统计研究表明,元坝地区须二段储层裂缝以低角度缝与水平缝为主;根据裂缝的成像测井与常规测井资料对储层进行了识别,判别模型法与R/S分形法相结合对裂缝识别效果较好,可以为进一步的勘探开发提供依据。The 2rd member of Xjiahe formation belongs to a typical tight sandstone reservoir,with characteristics of complex pore structure,poor physical properties and strong heterogeneity.Through statistical study on core data,the fractures in 2rd member of Xujiahe formation are mainly of low angle fractures and horizontal fractures.According to imaging logging and conventional logging data,the reservoirs identification has been carried out.In combination with R/S fractal method,the identification method is good and can provide guidance for exploration and development in the next step.
