高密度宽方位地震资料处理技术研究进展

The new progress of high-density and width azimuth seismic data processing

随着可控震源滑动扫描、独立同步扫描、高保真采集、点激发接收等高效采集技术的推出,高密度、宽方位地震勘探变得越来越经济可行,但随之也带来了高效采集噪声干扰、高保真采集数据分离等问题。这里着重论述了相关预测减去法谐波压制、多域压制邻炮干扰、线性反演拆分混叠数据等方法,同时展示了拟全三维和宽方位数据的处理成果。通过运用以上技术取得了较好的信噪分离效果,体现了宽方位数据在解决成像和方位各向异性问题上的优势。

With the development of high-- productivity vibrate, techniques such as slip-- sweep, independent simultaneous sweep, high fidelity vibrator seismic acquisition method, seismic exploration with width azimuth and high--density data has be- come viable economically. This paper introduces key processing techniques of these vibrate is acquisition methods, which are harmonic attenuation for slip--sweep, interfered shots de--blend for ISS, and separation of high fidelity acquisition data. This paper also discusses targeted processing techniques according to different geologic demands and gives results.
