摘　　要：基于伊犁盆地南缘的地震资料,开展了地震数据的处理和解释,并在此基础上,结合测井的声波和密度数据开展了波阻抗反演,实现了含矿目的层的砂体识别。实际应用结果表明,结合地震数据和测井的声波、密度数据进行波阻抗反演,可以实现对地层的岩性解释,识别10m以上厚度的砂岩层,查明勘查区的砂体展布情况,为铀成矿地质环境研究提供依据。Seismic data processing and interpretation was carried out in the southern margin of Yili basin.Impedance of the seismic data was inversed with the logging data,and sand body was reorganized in the target layer.The practical application results shew that the inversed impedance of seismic can be used in lithological interpretation and to recognize the sandstones with thickness over 10 m,which can find out the sand body distribution characteristics and provide evidences for the condition research of uranium mineralization.
