摘　　要：首先确定苏北盆地深凹带的凹中隆、近凹内斜坡深层和部分低凸起为深层勘探的有利区带,应用宽方位角采集技术获取该区的地震资料,采取的主要资料处理方法有振幅补偿、异常值及噪音压制、叠后去噪等,采用的综合解释技术为生油岩及储层特征研究、全三维解释方法、断层解释方法、相似图法地震属性分析技术。应用上述方法技术,完成了苏北盆地FM和HZB两个三维区块的深层资料采集、处理及解释研究工作,资料品质得到大幅提高,钻探效果明显。Wide azimuth seismic survey was shot in an attempt to delineate the structural features of deep targets in Subei basin. A series of techniques has been adapted to tackle the deep targets in seismic data processing and inter- pretation. The main data processing methods include amplitude compensation, noise suppression, and poststack denoising. Data interpretation methods include analysis of source rock and reservoir rock properties, true 3-D data interpretation, fault interpretation, and attribute analysis. These techniques have been used in the processing and interpretation on the 3-D data from blocks FM and HZB in Subei basin. The results are confirmed by drilling.
