摘　　要：基于流体识别因子敏感性的分析,有助于认识储层流体特征和分布规律。岩石物理参数实验测量是提取饱含不同流体时的岩石物理弹性参数最为直接的方法,为满足大港油田岐口地区油气勘探开发的需要,选取该区主力产能系板桥组14口井28块岩心样品进行岩石物理参数测量,利用高温高压条件模拟地层环境,通过驱替方法测出岩心样品在饱气饱水状态下的各种弹性参数,综合定性描述交会图技术和定量计算流体识别因子,得出储层流体的识别效果组合比单个流体识别因子更为显著,其中组合流体识别因子ρf对储层的气水识别最为敏感,为该区后续地震资料叠前反演该流体识别因子识别储层流体类型提供了重要的依据。Based on the sensitivity analysis of fluid recognition factors,it is helpful to cognize the characteristics and the distribution law of reservoir fluid.The experimental measurement of petrophysical parameters is the most direct method to extract petrophysical elastic parameters of rock with different fluid.According to the demand of oil and gas exploration in Dagang Qikou area,the 28 pieces of core samples of the 14 wells in the Banqiao Formation were selected for petrophysical parameters test.Formation environment under high temperature and high pressure was simulated.Various elastic parameters of core samples saturated gas and saturated water were measured with displacement method.Through qualitative analysis of crossplot and quantitative calculation of identification ability,it is concluded that combinatorial fluid recognition factors are more significant than individual fluid recognition factors in the reservoir fluid identification.Among them,the combinatorial recognition factorρf is the most sensitive to gas and water recognition.It provides important basis for pre-stack inversion of seismic data and reservoir prediction.
