【摘要】 在地震资料连片处理中,能量不均严重影响叠前时间偏移成像质量。为了解决这个问题,采用了CMP域逐点自动调整法。该方法综合每个CMP位置的覆盖次数和信噪比,给该CMP中每一个接收道一个覆盖次数和信噪比权值,根据CMP中每道加权值的大小,等比调整该道振幅值,以达到能量调整的目的。用该方法得到的桩海潜山资料质量得到明显提高。更多还原

【Abstract】 The energy inconsistency seriously affect the quality of pre-stack time migration In the merge processing.The automatic adjustment of CMP domain point by point method was used to solve this problem.This method synthesizes the coverage and the signal to noise ratio of each CMP location,and gives one coverage and signal to noise ratio weight of each trace in the CMP.According to the weighted value size in the CMP,the amplitude of the trace is adjusted geometrically to fulfill the purpose of energy adjustment.The quality of the buried hill data acquired from Zhuanghai had been improved dramatically.更多还原
