摘要(Abstract)：

为消除时移地震数据间由地震采集和处理等因素引起的差异,突出与油气藏内部流体变化有关的时移差异,需要对时移地震数据的监测测线与原始测线数据进行一致性处理。在时移地震数据互均衡处理、时差校正和分角度子波提取的基础上,对D气田时移地震的多个限角叠加地震数据进行叠前同时反演,得到纵波波阻抗、横波波阻抗、纵横波速度比和密度等属性的时移差异数据。反演的时移差异属性对D气田的开发动用区块表现清晰,能够进行气藏模型优化,预测剩余储量分布,对D气田的二次开发具有指导意义。

关键词(KeyWords)：时移地震技术;叠前同时反演;限角叠加地震数据;时移差异;气藏模型优化;剩余储量
