摘　　要：对于陆相沉积的薄砂岩储层,其地震储层预测的可信度与油气勘探开发的关系十分密切。采用近几年发展起来的地震非线性随机反演方法,以测井、地质信息作为约束条件,通过拾取有效的地震波振幅、相位和频率信息,对胜利油田孤岛南区馆陶组薄砂岩储层进行了钻前预测。对26口新钻井的统计结果表明,预测与实钻吻合。这表明该地震储层预测方法具有较高的可信度,在油气田勘探开发中具有良好的应用前景。The seismic prediction creditability of reservoir in the thin sandstone of continental deposits is intimately related with oilgas exploration and development. The seismic nonlinear random inversion method developed in recent years was used to predict the thin sandstone reservoirs of Guantao Formation in the south part of Gudao area in Shengli Oilfield by taking the logging and geologic data as the constrained conditions and by extracting the effective information of amplitude, phase and frequency of seismic wave. The prediction results of 26 newly drilled wells have matched well with the actual drill situation,which shows the seismic prediction method has good creditability and applicability in the process of oil and gas exploration and development.
