摘　　要：在4D地震监测中,储层特性的变化主要是通过拉梅常数的变化才最终表现为地层速度和实际地震响应的变化,因此,在一定条件下,拉梅常数应当是储层特定变化最直接和灵敏的标志。本文详细叙述了拉梅常数反演的方法,并将其应用于实际4D地震资料的反演和解释中。良好的反演结果表明拉梅常数反演用于4D地震监测是切实可行的。In 4D seismic monitoring, the variation of reservoir features is mainly indecated by the changes of Lame constant, and eventually represented as velocity of layer and seismic response. Hence, Lame constant should be the most direct and sensitive indication for the variation of reservoir features under certain condition. In the paper, inversion methods of Lame constant are introduced and used actually in the inversion of 4D seismic monitoring data. The results show that it is feasible to use Lame constant inversion into 4D seismic monitoring.
