摘要
本文介绍了深井井间纵、横渡资料的层析成像方法。该方法利用正演模型识别波场，用交互法拾取走时，采用界面网最小走时射线追踪法进行射线追踪，并用反演样条系数代替反演慢度，最后合成速度场。实际资料处理结果表明，反演结果与测井曲线的相关性较好，几套高速砂层反映得比较清楚。
We recommend the tomography method for P and S-waves of deep crossholeseismic survey. This method involves forward modeling wavefield identification,interactive travel time pickup,minimum travel time ray tracing in the interface net,spline coefficient inversion instead of slowness inversion and final velocity field synthesising. Real data processing result shows that the inversion result correlates withlogging data desirably,several high velocity sand beds being seen distinctly.
