摘　　要：GeoEast地震资料处理解释系统作为功能齐全的一体化处理解释平台,经过近年来的持续完善和推广应用,已成为塔里木油田碎屑岩研究的主流平台。特别是通过多年生产科研一体化,优选出一系列实用性较强的特色技术,能较好地解决油气勘探开发中的一些复杂地质问题,有着广泛的适应性。以塔里木盆地桑塔木三维区为例,结合GeoEast系统的特点,针对该区碎屑岩开展保幅保真的井控叠前深度偏移处理,并应用GeoEast解释系统实现全流程解释,在提高目的层分辨率的同时保持了较高信噪比,保幅保真性好,地震特征明显,能够满足构造解释和储层预测需要,确定了独立断块11个,连续部署4口井,均获得高产,为该区后续滚动开发提供了资料保证。As an integrated seismic data processing and interpretation system, GeoEast has become a mainstream platform of clastic rock study in Tarim Oilfield after continuous improvements and applications for years. In the production and scientific researches,a series of effective approaches are selected, which can solve complex geological problems in the hydrocarbon exploration and development. Recently, we have worked on a 3 D seismic survey in the Sangtamu Area, Tarim Basin, with a few approaches provided by GeaEast. For data processing, the well-controlled and amplitude-preserving prestack depth migration is carried out. For the data interpretation, we complete the whole interpretation process and achieve obvious results. Both the resolution and the signal-to-noise ratio are greatly improved, clastic rock characteristics and deep targets are clear, which meet the needs for structure interpretation and reservoir prediction. Based on our study, 11 independent fault blocks are identified, and four wells deployed that all achieved high oil yield. Our study provides a good basis for the future subsequent rolling development in this area.
