摘要
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。胜利桩海地区23块共1500km2三维地震资料一致性处理取得了良好的效果。
3D seismic data merge process is a set of fine and complex digital process. According to the particularity anddiffrentia such as the frequency, phase, move out, signal-to-noise ratio of each 3D seismic data, processing methodssuch as prestack energy consistency, phase consistency and amplitude consistency are used to make the consistencycompensation and correction for their energy, amplitude and phase, which assure the consistency of the data mergeg,with an aim in maintaining its original quality each 3D block while some improvement on its signal to noise ratio canbe seen. We have got good results in the 3D seismic data consistency processing of the 23 blocks (1500km2) inZhuanghai area of Shengli Oil Field.
