摘要
针对张家湖地区由于多种因素造成的原始资料能量不足、信噪比低等现象,结合该区的地震地质条件,在分析现有资料的基础上提出了如下处理成像方法:1)采用叠前去除该区发达的规则线性干扰,提高资料信噪比;2)采用地表一致性振幅补偿远偏移距及深层地震记录能量,突出弱相位,提高信噪比;3)针对构造高点进行精细的速度分析和剩余静校正迭代处理,提高叠加剖面品质。
Influenced by many factors, problems of energy shortage of source data and low SNR are obvious in Zhangjiahu. In response to them, imaging processes are proposed： The first is to improve data SNR by using pre-- stack to remove well--developed regular linear disturbance from the work zone. The second is to highlight weak phase position and improve SNR by using surface uniformity amplitude to compensate offset distance and deep seis- mic recording energy. The last is to improve the quality of stacked section through careful velocity analysis of high spot of structure and iteration process of 3D residual static eorreetion.
