摘    要:由于地震资料分辨率较低,保真性和保幅性较差,原有技术难以满足研究区勘探开发的要求。针对此问题,通过地震资料重处理,尝试应用反Q滤波、谱整形技术和子波整形反褶积等方法进行提高分辨率的处理,以改善三维地震品质。研究表明,子波整形反褶积方法的效果明显最优,在不改变原始资料相对振幅、波形特征的情况下,拓频后低频和高频均有不同程度提高。同时,该方法可减少人为控制因素,满足保真保幅处理原则,较为实用。

关 键 词:珠江口盆地  惠州地区  提高分辨率  反Q滤波  谱整形技术  子波整形反褶积

Abstract:Because the resolution of seismic data is relatively low, fidelity, amplitude is poor, it is difficult to meetthe current requirements of the exploration and development block in seismic data processing. According to these,the application of inverse Q filtering, spectrum shaping technology and wavelet shaping deconvolution are used toimprove resolution method. All in all, wavelet shaping deeonvolution effect is the best method among the threemethods, without changing the original data of relative amplitude, waveform ehatacteristic case, extension of thelow and high frequency is improved at the same time, reduce man -made factors, meet the fidelity amplitude pre-served processing principle, and is a practical improved resolution method.
Keywords:Pearl River mouth basin  Huizhou area  improve resolution ratio  inverse Q filter  spectrum shaping  wavelet shaping deconvolution
