模拟上下源、上下缆地震资料配套处理

A seismic data processing approach associated with simulated over/under source and over/under streamer acquisition

本文对模拟上下源、上下揽地震资料进行了处理,在处理过程中对不同震源激发、电缆接收深度数据进行合并处理,将浅层电缆接收到的高频成分和深层电缆接收到的低频成分进行叠加,并对虚反射进行压制,达到拓宽地震资料频带、提高地震资料品质的目的。

The paper presents a seismic data processing approach associated with simulated over/under source and over/under towed-streamer acquisition,which is a merging processing technique for the data acquired with different source depth and towedstreamer depth.Stacks merge high frequency data acquired in shallow streamers with low frequency data acquired in deep streamers.This data merging can not only suppress ghosts and broaden frequency band,but also improve data quality.We have simulated seismic data acquired by over/under source and over/under towed-streamer based on test data with different source depth and towedstreamer depth,and processed the simulated seismic data.The processing result proves the validity of the proposed approach.
