摘　　要：地震属性主组分分析预测技术是一种精细测井约束反演技术,其最大优点是以测井资料为基础,地震资料为桥梁,最终得到的波阻抗体几乎接近或达到测井分辨率;除可以提供岩性参数外,还可提供油藏参数。该技术应用于玉门青西油田取得了良好的效果,为油田沉积相划分、井位论证、地质综合研究提供了一定的依据。2002年提供的6口井位已有4口井获工业油流,为油田的产能建设做出了贡献。Principal component analysis and prediction is a technique of detailed well log constraint inversion. Based on well log data and seismic data, it can be applied to provide the wave impedance as similar as well log resolution in accuracy, including lithology and reservoir rock parameters. Good results are obtained from its application to Qingxi oilfield in sedimentary facies classification, well location demonstration and integrated geological studies. Commercial oil flow has been found in four of six wells drilled in 2002, which contributes to Qingxi oilfield in its productivity construction.
