三维地震资料连片的一致性处理技术

三维地震资料连片处理是一套复杂而精细的数字处理工作。根据各区块三维地震资料的频率、相位、时差、信噪比等的特殊性和差异性，采用叠前能量一致性、相位一致性和振幅一致性处理方法，对能量、振幅、相位等有效地进行一致性补偿和校正，使各区块资料在保持原有品质的前提下，既提高了信噪比和分辨率，又保证了资料整体拼接的一致性。应用该方法处理胜利桩海地区23块共1500km^2三维资料，取得了良好的效果。

Consistency processing technology of 3D seismic data jointing

3D seismic data joining processing is a set of complex and fine digital processing. According to the particularity and differentia of the frequency, phase, moveout, signal-to-noise ratio and so on in different blocks, the methods of prestack energy consistency, phase consistency and amplitude consistency are applied to making the consistency compensation and correction effectively for the energy, amplitude, phase etc. Signal-to-noise ratio and resolution are enhanced, and the consistency of the whole data joining is ensured predicated on keeping the original data quality in each block. We have got good results in the 3D data consistency processing of the 23 blocks ( 1500km2 ) in Shengli Zhuanghai area.
