转换横波合成记录制作方法
|
摘要
对转换波地震剖面的解释过程中转换横波的合成记录标定问题进行研究,提出转换横波合成记录制作方法,即将纵横波声波测井曲线相加,得到伪转换波声波测井,从而得到伪转换波反射系数,再用常规的制作合成记录的手段制作转换波合成记录,可以得到时间准确、振幅特征近似准确的结果。该合成记录制作方法简单、快捷,实际资料的应用结果证明了制作方法的有效性和良好的应用前景。
The synthetic seismic correlation of conversion S-wave for the interpretation of P-S wave seismic data was researched,and a method of making P-SV shear wave synthetic seismic record was proposed. According to deduction and statistics,pseudo P-S wave sonic log can be gotten by the P-wave sonic plus S-wave sonic,and good pseudo reflection coefficient of P-S wave can be gotten.Then,synthetic P-S seismic record can be made by conventional ways,and a synthetic P-S seismic record with correct time and approximate amplitude can be obtained. The method is characterized by simplicity. The application results of real data proved the validity and the foreground of the method.
