摘　　要：随着勘探难度的增加和非常规油气层的出现,现场识别流体类型越来越困难,为了充分挖掘FLAIR实时地层流体分析录井在油气水层解释的数据优势,针对不同研究区块储层流体特征和FLAIR实时地层流体分析录井技术特点,共筛选出25个气测参数及其派生参数,通过特征权重算法,针对不同研究区分别优选出最优的解释参数,建立解释评价图版。在莱州湾凹陷的5口井的应用中,油水层解释符合率达到90.0%,应用效果较好,对于快速、准确地识别地层流体,发现油气显示效果显著,增强了流体录井的现场使用价值,具有良好的推广应用价值。With the increase of exploration difficulty and the discovery of unconventional oil and gas reservoirs,it is more and more difficult to identify fluid types on site.In order to fully exploit the data advantages of FLAIR real-time formation fluid analysis logging in oil,gas and water layer interpretation,25 gas logging parameters and their derived parameters are selected according to the reservoir fluid characteristics of different research blocks and the technical characteristics of FLAIR real-time formation fluid analysis logging.The optimal interpretation parameters are selected for different research areas through the feature weight algorithm,and interpretation and evaluation chart is established.In the application of 5 wells in Laizhouwan sag,the coincidence rate of oil-water layer interpretation reaches 90.0%,and the application effect is good.For the rapid and accurate identification of formation fluid,it is found that the oil and gas display effect is remarkable,which enhances the field application value of fluid logging and has a good popularization and application value.
