【摘要】 从江汉平原海相地震资料特点出发,依据平原海相地震资料处理的原则与方法,提出了以叠前数据优化、振幅频率相位一致性处理、倾角时差(DMO)等为重点的处理方法。同时,还首次在江汉提出了广角反射信息提取、共中心点(CMP)超道集交互动态动校正切除等处理新方法,确定了合理处理流程。通过大量实际资料处理表明,该方法在江汉地震平原海相资料处理中,发挥了独特重要作用。更多还原

【Abstract】 Based on the characteristics of the marine strata seismic data of Jianghan plain, and the processing principle and the method of plain marine strata seismic data processing, new techniques of seismic data processing focused on data optimization, consistency management of amplitude frequency phase,dip moveout (DMO) etc,is brought forward. And the techniques such as wide angle reflection information extraction, interacted dynamic NMO correction muting in CMP super-gather, are first brought forward in Jianghan Oilfield , and a proper seismic data processing flow is confirmed . This method has a special effect in processing marine strata seismic data of Jianghan Plain, which is demonstrated with a great deal of practical data processing.更多还原
