%X 针对窄小河道含油砂体预测难、垂向分辨率和平面分辨率不能兼得的问题，形成了基于地震波形特征的全局寻优的非线性地震反演砂体预测技术，该技术能够充分利用非线性地震反演提高了纵向分辨率高，同时基于地震基于波形特征反演技术又提高了横向分辨率；利用该地震反演技术河道砂体预测精度由过去的76.3%提高到83%，取得了较好的效果，该技术对窄小河道砂体的精细预测具有较好的指导意义。<br />
In order to solve the problems of difficult prediction of oil-bearing sand bodies in narrow and small river channels, the non-linear seismic inversion sand body prediction technique based on global optimization of seismic waveform characteristics is formed, this technique can make full use of the nonlinear seismic inversion to improve the vertical resolution, and also improve the horizontal res-olution based on the seismic waveform feature inversion. By using this seismic inversion technique, the prediction accuracy of channel sand body has been improved from 76.3% to 83%, and good re-sults have been achieved.
