摘　　要：胜利西部银川盆地发育巨厚的新生界地层,但由于资料相对较少,盆地内古近系清水营组是否具有良好的生烃潜力一直是制约该盆地勘探的主要因素。针对这一主要问题,本文从地震资料入手,利用地震剖面、速度谱资料,结合野外地质、已钻探井,开展地震相、沉积相分析并结合层速度分析方法进行了烃源岩的研究与预测,该综合研究方法对西部其他低勘探程度区烃源岩预测具有重要借鉴意义。Yinchuan Basin,one of Shengli western prospect,developed very thick Cenozoic formation,but due to relatively less data,whether there are qualified source rocks in Cenozoic Qingshuiying Group has been a critical factor that restricts exploration of Yinchuan Basin.In view of this critical problem,seismic facies and sedimentary facies were analyzed beginning with seismic data,using seismic sections and velocity spectrum,combining field geology and drilled exploration wells,and source rock research and prediction were carried out combining horizon velocity analysis method.The comprehensive research method can be used for significant reference in source rock prediction for other area with low exploration degree in the western.
