针对辽河盆地深层地震资料反射不清，信噪比及偏移成像精度低的情况，采用振幅补偿、叠前去噪、剩余静校 正、多次波压制及叠后去噪等技术提高信噪比；采用ＤＭＯ、偏移速度场平滑、叠前深度偏移等技术提高偏移成像精度。使 信噪比及偏移成像精度均有明显提高，极大地提高了深层地震资料的质量。
In view of the low reflection of deep seismic data in Liaohe Basin and low signal-to-noise ratio and offset imaging accuracy, the techniques of amplitude compensation, pre-stack denoising, residual static correction, multiple suppression and post- The techniques of DMO, smooth migration velocity field and pre-stack depth migration are used to improve the accuracy of migration imaging. So that the signal-to-noise ratio and imaging accuracy are significantly improved, greatly improving the quality of deep seismic data.
