摘　　要： 由于中国东部地区陆相砂岩油藏岩性变化快,构造特征比较复杂,精细油藏描述地层对比研究中常常出现较多的油水关系矛盾现象。通过分析认为,造成油水关系矛盾的主要原因有岩性变化或尖灭、构造特征认识不清晰、地层对比存在问题、测井综合解释对油水层的认识存在错误以及储层损害等,由此提出通过高精度构造解释、精细地层对比、单井井史分析及储层保护、试油试采资料分析以及油藏动态分析等方法来解决精细油藏描述研究中存在的油水关系矛盾现象。 The continental sandstone reservoirs in eastern China are characterized by drastic lithology changes and complex structural features.Contradictory oil-water relationship is often seen in fine reservoir description and stratigraphic correlation.Analysis indicates that the main reasons for contradictory oil-water relationship include lithologic change or pinchout,unclear recognition of structural features,questionable stratigraphic correlation,incorrect logging interpretation of oil and water layers,reservoir damage and so on.Hence it is proposed to solve the problem of contradictory oil-water relationship in fine reservoir description through methods such as high accuracy structural interpretation,fine stratigraphic correlation,single well history analysis and reservoir protection,and analyses of production test data and reservoir performance.
