摘　　要：录井过程中准确识别油气显示对油气勘探具有重要意义。渤海潜山储层录井油气显示识别一直面临着流体性质难判断、油气丰度难评价、油气性质难鉴别等难题。通过分析渤中19-6太古界潜山储层含油气荧光录井特征,建立了细分岩屑荧光颜色法,将岩屑荧光颜色分为5类:蓝白色类、亮黄色类、暗黄色类、无荧光类和浅白色类,对应划分了Ⅰ—Ⅴ类储层。结合前人对潜山内幕油气运移研究成果,建立了岩屑荧光颜色与潜山裂缝型储层中含油品质的关系,佐证了岩屑荧光颜色与油气充注的关系。细分岩屑荧光颜色法在渤中19-6潜山评价中应用效果好,为后续潜山勘探中裂缝型储层油气快速准确识别提供了借鉴。It is of great significance for oil and gas exploration to accurately identify oil and gas displays during logging. The identification of hydrocarbon display in Bohai buried hill reservoir logging is always confronted with difficult problems such as fluid property judgment, hydrocarbon abundance evaluation and hydrocarbon property identification. By analyzing the characteristics of oil and gas fluorescence logging in BZ19-6 Archaean buried hill reservoir, the fluorescence color method of subdivided cuttings has been established, the cuttings fluorescence colors are divided into 5 categories: blue white, bright yellow, dark yellow, non fluorescent and light white, and the corresponding type Ⅰ—Ⅴ reservoirs are divided. In combination with previous research results on hydrocarbon migration inside buried hills, the relationship between the cuttings fluorescence color and the oil quality in buried hill fractured reservoirs has been established, which proves the relationship between the cuttings fluorescence color and oil-gas filling. The subdivided cuttings fluorescence color method has been applied to the evaluation of BZ19-6 buried hill with good results, which provides a reference for rapid and accurate oil and gas identification of fractured reservoirs in subsequent buried hill exploration.
