【摘要】 零偏或非零偏VSP测井资料具有在表层低降速带下激发和接收,以及地震波在地层中单程传播的特点,它极大地减少了表层低降速带的吸收、地震波在传播路径中的衰减以及地表各种噪音干扰对有效信号的能量和频率的影响。与地面地震采集资料相比,具有更强能量和更宽的频率成分。因此,综合利用微测井、VSP资料和地面地震资料,对地震波在不同埋深目的层中传播时的振幅和频率进行准确分析和研究,以确定地震采集中能获得的最高频率,这样能更合理地指导野外地震采集试验及评价试验资料效果。更多还原

【Abstract】 Because zero-or nonzero-offset VSP data has ability to reduce influence of low velocity layer,shorten propagating path of seismic wave and lessen disturb of surface noise,it can remedy some defects of surface data.After influence of disturb from surface is eliminated,frequency and amplitude of seismic wave which transmitted exploration target layer in different depth can be determined by VSP data.By comprehensive utilization of logging,VSP data and surface seismic data,we can get the highest frequency of seismic acquisition.So it can guide the test of seismic acquisition and evaluation test data.更多还原
