【摘要】 本文分析了三维转换波时距方程,并由该方程介绍了三维三分量数据坐标旋转理论和旋转方程。通过理论模型和实际数据的处理表明,选择正确的坐标旋转方法对于获得较高信噪比的转换波数据至关重要;将纵波静校正量应用于转换波数据处理,在共检波点域计算检波点静校正量,是取得较好转换波静校正结果的一种方法。更多还原

【Abstract】 The paper analyzed the 3D converted wave time-distance equation, and from that introduced 3D3C data coordinate rotation theory and rotation equation. It is showed by theoretical model and practical data processing that selecting correct coordinate rotation method is important to acquire converted wave data with higher S/N ratio; using P-wave statics for converted wave data and computing statics at receiver points in common-receiver-point domain is a method achieving good static corrections result of converted wave.更多还原
