%X 针对Berkine盆地地震数据强烈的线性和随机噪声、不同类型的多次波、复杂的构造、尖灭和小断层等特点，分别采用线性噪声衰减技术去除干扰波，多次波压制技术压制多次反射波，叠前时间偏移技术提高地震数据的横向分辨率，以及叠后高分辨率处理技术进一步改善地震记录的品质。通过在Berkine盆地油田实际数据处理的应用，地震物探资料的分辨率和信噪比得到明显提高，特别是目的层同相轴品质明显改善。<br />
The seismic data in Berkine basin is characterised by strong liner interference, random noise and different multiple waves. The data quality is affected by complex underground structure, such as pinch outs, subtle faults and so on. We use linear noise attenuation technique to remove interference wave, multiple wave suppression technology to suppress multiple reflection wave, and prestack time migration technology to improve lateral resolution of seismic data. Besides, we use post-stack high resolution processing technology to further improve the quality of seismic record. Through the application of these effective data processing steps, the resolution and signal-to-noise ratio of seismic geophysical data have been significantly improved, especially the quality of the in-phase axis of the target layer.
