【摘要】 采用复地震道技术可以提取瞬时相位,瞬时相位参数对地震资料解释、油藏描述和获取岩性信息有重要意义。由于小波具有良好的时频局部特征,因此可以利用小波变换求取不同尺度下的瞬时相位参数。本文对地震波在小波变换下的相位特性进行了初步探索。试验表明,本方法可有效地确定断层和追踪地震层位信息更多还原

【Abstract】 Complex seismic trace technique may be used to obtain instantaneous phase; and the instantaneous phase parameter is of great importance to seismic data interpretation, reservoir description and lithologic information obtainment. The wavelet transform may be taken to have instantaneous phase parameters of different scales because wavelet has good partial time and frequency characters. Authors have made initial research on phase characteristic of seismic wave under wavelet transform. It is shown that the method can be used to locate faults and to trace seismic horizons.更多还原
