摘　　要：石南油田石南 21 井区,是 2003 年准噶尔盆地的重点评价区块,也是加快准噶尔盆地腹部油气勘探、增储上产最现实的区块之一.该区块实施了三维地震处理解释一体化,在以复杂地表条件综合建模静校正、针对岩性圈闭处理的振幅补偿、组合反褶积提高分辨率为关键技术的精细目标处理基础上,综合运用全三维解释、波阻抗反演、神经网络分析等多种地震技术方法和手段,对石南 21 井区河道砂体进行识别与描述,有效地指导了评价井的部署和实施,为在准噶尔盆地开展寻找岩性圈闭积累经验.Well SN21 area of the Shinan oilfield increased the reservoir in the Junggar basin in 2003. Studies of integrative 3D seismic data processing and interpretation were made in the area. Key techniques which are suitable for lithological trap of complex surface situations: integrative model static correction, amplitude compensated and compounding deconvolution for high solution, and fine target processing, seismic technique of true 3D seismic data interpretation and (audio) impedance inversion and nerve network are used to identify and depict channel sand body in the well SN21 area. The efficiency guided appraising well was deployed and implemented and led to the identification of a lithological trap in Junggar basin.
