摘　　要：华北油田留楚构造带地质条件复杂、储集层非均质性强,不同层位、不同深度的油气水性质差异,加大了地层流体准确识别难度,录井、测井的解释效果均不理想。为探索该区储集层流体性质评价的有效方法,使用SPSS统计软件,将多种录井、测井技术结合应用,通过参数优选,从35个参数中优选5个,对留楚构造带已有试油资料42口井147层的各项录井、测井参数进行因子分析,在保留大部分信息的情况下,提取少数几个因子,用于建立因子分析解释图板,进而对储集层产能进行评价。模型的回判验证符合率达到93.9%,该模型在留楚构造带应用35口井,经试油验证,解释符合率达到78.2%,提高了近6个百分点。The geologic conditions of Liuchu structural belt in Huabei Oilfield are complex,the reservoir heterogeneity is strong,the oil,gas and water properties of different horizons and depths are different,which increases the difficulty of accurate identification of formation fluid,and the interpretation effects of mud logging and well logging are not ideal.In order to explore the effective method of reservoir fluid property evaluation in this area,SPSS statistical software is used to combine various mud logging and well logging techniques.Through parameter optimization,5 out of 35 parameters were selected.The factors of mud logging and well logging parameters in 147 layers of 42 wells with well test data in Liuchu structural belt were analyzed.In the case of retaining most of the information,a few factors are extracted to establish the factor analysis interpretation chart,and then the reservoir productivity is evaluated.The coincidence rate of back judgment verification of the model was 93.9%.The model has been applied to 35 wells in Liuchu structural belt,and well test proves that the interpretation coincidence rate reaches 78.2%,increasing by nearly 6 percentage points.
