【摘要】 高密度地震资料具有高信噪比、高分辨率和高保真度的明显优势,也对静校正的精度提出了更高的要求。基于高密度地震资料波场信息丰富和初至波信息清晰的特点,本文提出了一套适合高密度地震资料且能够满足高精度处理要求的剩余静校正方法。通过依次应用多域迭代折射波剩余静校正、分频模型迭代剩余静校正和非地表一致性剩余静校正方法,有序地计算高密度资料的剩余静校正量,进一步解决中、短波长静校正问题。实际资料的应用表明,该方法能够有效地解决高密度地震资料的剩余静校正问题。更多还原

【Abstract】 With high S/N ratio,high resolution,and high fidelity,high-density seismic data need better static corrections to be processed than conventional seismic data.The widely used tomographic inversion statics can properly solve the problem of long wavelength corrections,but cannot solve the problem of short wavelength corrections.Based on theoretical analysis and field data study,we propose in the paper comprehensive static correction approach including multi-domain iteration residual refraction statics,sub-frequency-band model iteration residual statics,and nonsurface-consistent residual statics to calculate residual statics for highdensity seismic data in order solve both long wavelength corrections and short wavelength corrections.Applications to field data show the effectiveness of the proposed approach.更多还原
