戈壁地区可控震源线性干扰波衰减方法探讨

Discussion of Falloff Method of Vibroseis Linear Interference Wave in the Gobi Desert

柴窝堡工区地震测线线性干扰大,尤其是浅层的干扰。去除干扰、优化叠前数据是保证地震剖面成像效果的关键。经对比研究后认为,"开时窗道组合+面波衰减"处理方式适宜用于柴窝堡工区及相似地区地震资料的叠前处理,处理后的叠加剖面,在同相轴的连续性和能量上都有所改善和提高。

Seismic line in Chaiwobao work zone suffers from large linear interference, especially from that in superficial zone. Wiping off interference and optimizing pre--stack data is the focus of guaranteeing imaging effect of seismic section. Comparative study concludes that process mode of windowing trace arrays plus ground roll attenuation is suitable for pre--stack processing of seismic data from Chaiwobao work zone or the regions similar to it. All the stacked sections processed have improved in the event＇s continuity and energy.
