摘　　要：按照“模式指导、岩心标定、动静结合、层次分析”的研究思路,综合应用丰富的岩心、测井、动态监测等资料,开展沉积微相、构型表征及储层精细评价研究,创新应用冲积扇7级体系沉积模式,剖析干旱型冲积扇优势构型单元空间叠置样式、差异化建立双物源5种单井相模式。在此基础上开展块状砂砾岩体有效储层识别,应用交会图聚类分析法,优选14项敏感评价参数开展储层分类评价,表征储层质量差异,明确优势储层空间分布特征。Following the research approach of“pattern guidance,core calibration,dynamic and static integration,and hierarchical analysis”,a comprehensive application of rich core,logging,dynamic monitoring and other data has been conducted to study sedimentary microfacies,configuration characterization,and reservoir fine evaluation.Innovative application of the 7-level system sedimentation model of alluvial fans has been carried out,analyzing the spatial stacking style of dominant configuration units in arid alluvial fans,and establishing five single well facies models with dual sources through differentiation.On this basis,effective reservoir identification of block shaped sandstone and gravel rock masses was carried out,and the intersection graph clustering analysis method was applied to select 14 sensitive evaluation parameters for reservoir classification and evaluation,characterizing the differences in reservoir quality and clarifying the spatial distribution characteristics of advantageous reservoirs.
