| 摘 要： | 利用突出泊松比变化的Shuey简化方程推导出逐点计算泊松比的反演公式.在泊松比反演之前，对地震数据进行剩余时差校正，可以使振幅随炮检距（或入射角）的变化趋势更明显，可以提高反演的精度.通过对理论模型及实际资料的处理，说明这种反演方法是可行的，由反演结果可以预测低泊松比异常，寻找天然气.

| Abstract: | The Poisson's ratio inversion formula is derived from Shuey reduced equation which stresses Poisson's ratio change. Residual moveout correction to seismic data will make the change trend of the amplitude versus offset (or incident angle) more obvious before Poisson's ratio inversion. It can improve the precision of inversion. Though the treatment to theory models and real data, this inversion method is proved practicable. Low Poisson's ratio anomalies can be predicted and natural gas can be found from inversion results. |
