摘　　要：伊通盆地是吉林油田近十年来勘探并初现储量规模的复杂性断凹盆地,其中构造解释和砂砾岩储层预测一直是攻关的难点。在探索适合伊通盆地地震资料解释的过程中,在已有的多种适用地震技术中,通过对这些技术的优化与组合,利用瞬时相位属性技术实现了盆地目的层底砾岩与基底花岗岩的识别;利用时间切片与三维可视化技术的结合实现了盆地老资料有效的构造解释;通过地震属性分析技术与波阻抗反演技术的结合实现了岩性圈闭的有效识别。Yitong Basin is a complex fault depression basin with large-scale reserves explored in Jilin Oilfield in the past ten years. Structural interpretation and glutenite reservoir prediction are always difficult in the basin. During the process of probing into seismic data interpretation applicable to the basin, by optimizing and combining multiple applicable seismic technologies, basal conglomerate and basement granite of the target layer of the basin are identified by using instantaneous-phase attribute technologies. Effective structural interpretation of old data of the basin is fulfilled by combining the technology of time slice with the 3-D visualization technology. Lithologic traps are identified effectively based on the combination of seismic attribute analysis and wave impedance inversion.
