摘　　要：本文针对吐哈重点探区目标区块的地质任务和资料处理主要难点,采用GeoEast处理系统的精细目标处理特色技术系列,主要包括GeoEast处理系统多方法组合静校正技术、组合去噪提高信噪比技术、组合反褶积提高分辨率技术以及叠前时间偏移成像技术。通过这些特色技术的应用,同时加强处理解释一体化研究,资料保真及处理时效得到提高,及时为落实圈闭及井位提供处理成果资料,提高了勘探效率及准确率。To meet the requirements of the hydrocarbon exploration and development in Tuha Basin, seismic data should be well processed and its quality should be much improved. For this purpose we use GeoEast target-oriented processing technology to process seismic data of some surveys in Tuha Basin, which includes mainly combined static corrections, combined de-noising approaches to improve the signal-to-noise ratio(SNR), combined deconvolutions to improve data resolution, and prestack time migration(PSTM).Then we adopt integrated processing and interpretation approaches. Finally we carry out reservoir identification and provide well deployment proposal for the future exploration.
