摘要
本文实现了基于三维τ-p变换的鬼波压制技术,对南海文昌A凹陷区三维地震资料进行鬼波压制,偏移数据体中紧随一次波信号的鬼波旁瓣得到明显压制,地层反射更加清晰、信噪比显著提高。实际数据处理结果证明了三维τ-p域鬼波压制技术对浅水区常规拖缆三维地震鬼波剔除的有效性。
This paper implements the deghosting technique based on 3Dτ-p transform and conducts the ghost elimination for the 3D seismic data of the Wenchang-A depression in the South China Sea.The ghost-event sidelobes near the primary events are effectively suppressed in 3D migrated data volume.The reflection of strata is clearer and the signal-to-noise ratio is improved remarkably.This field data experiment verifies the effectiveness of the 3Dτ-p domain deghosting technique in shallow water area.
