摘　　要：渤中凹陷太古界潜山储层因受岩性和构造等多重因素影响,油气分布不均,储层非均质性强,流体性质复杂,录井过程中面临着流体性质难判断、储层含水不确定等难题。通过分析渤中M构造太古界潜山录井特征,建立了渤中M构造太古界潜山裂缝型储层流体性质随钻识别方法,采用气测组分纵向趋势法及图板法、裂缝含油气丰度交会图板法及图谱法,结合荧光显示情况,综合判断油层和水层,切实提高了太古界潜山流体性质识别的准确率。该方法在渤中M构造潜山储层流体性质评价中应用效果明显,能够为勘探决策提供重要依据,具有推广意义。The buried hill reservoir in Bozhong Sag is affected by multiple factors such as lithology and structure,with uneven distribution of oil and gas,strong reservoir heterogeneity and complex fluid properties.It is difficult to judge fluid properties and uncertain reservoir water cut during logging.Based on the analysis of logging characteristics of Archean buried hill in Bozhong M structure,the identification method of fluid properties while drilling in fractured reservoir of Archean buried hill in Bohai Sea is established in this paper.The vertical trend method and plate method of gas logging composition,cross plate method and atlas method of oil and gas abundance of fractures are adopted to comprehensively judge oil layer and water layer combined with fluorescence display,which effectively improves the accuracy of fluid properties identification of Archean buried hill.The application of this method in reservoir fluid evaluation of buried hill in M structure in Bozhong is obvious,which can provide important basis for exploration decision-making and has popularization significance.
