摘　　要：针对常规纵波地震资料在断层检测、岩性判别和流体识别等方面有局限性的3D3C地震技术增加了转换波信息，提高了气层及流体边界检测的可靠性。2006年在大庆喇嘛甸油田开展的3D3C地震技术研究表明，利用3D3C地震资料提供的纵波、转换波资料及由此联合反演导出的泊松比、纵横波速度比等弹性参数能够直接预测气层和岩性，预测结果与实际情况吻合很好，提高了地震预测油气藏储层的可靠性和精度。In the light of the limitations of conventional P-wave seismic data in fault detection, lithologie ＆ fluid i- dentifications and so on, 3D3C seismic technology adds the converted wave information and enhances the tested re- liability of the gas reservoirs and fluid boundary. In 2006, 3D3C seismic technique was conducted in Daqing Lama- dian Oilfield. The research resuhs show that the interpreted P-wave ＆ converted wave by 3D3C seismic data and the following elastic parameters： the Poisson ratio, P-S wave velocity ratio and so forth jointedly inverted by the a- bove data can directly predict the gas reservoirs and lithology, and moreover the predicted results are very accordant with the facts, thus the reliability and accuracy of the seismic prediction of oil and gas reservoirs are improved.
