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。
Because of the rapid change in lithology of continental sandstone reservoirs in the eastern part of China and the structural characteristics of the reservoirs, the structural characteristics of the reservoirs in the fine reservoirs are often complicated and often contradicted. Through analysis, it is suggested that the main causes of the contradiction between oil and water are lithology change or pinch-out, unclear understanding of structural features, stratigraphic contrast, faulty understanding of well logging interpretation and reservoir damage, etc., The contradiction between oil and water existing in the study of fine reservoirs is solved by means of high-precision structural interpretation, fine stratigraphic correlation, single-well well history analysis and reservoir protection, test-oil production data analysis and reservoir dynamic analysis.
