【摘要】 东营城区高精度三维为重复采集资料。受城区极为复杂的地表条件限制,资料采集时采用了炸药震源和可控震源,造成了资料在频率和相位方面的较大差异,严重影响了资料的同相叠加,也影响了资料的信噪比和分辨率。为此,在资料处理中开发并应用了相位匹配处理技术,有效地解决了资料间的相位不匹配问题,很好地实现了同相叠加。更多还原

【Abstract】 The high precision 3D seismic data acquired from the city zone of Dongying are re-acquired data. Limited bycomplex surface of the zone, so two kinds of sources,dynamite and vibroseis,were taken during acquiring, it causedrelatively big difference in the frequency and amplitude, exerted a serious influence on the in-phase stack of data,and the signal-noise ratio and resolution of data too. For this reason, the phase matching technique were developed andintroduced during processing, the mismatching problem of phase between data were solved efficiently and realizedin-phase stack.更多还原
