【摘要】 本文根据苏丹沼泽地区的地震资料采集特点,利用BGP苏丹地震资料处理中心现有的处理系统,通过水中检波器与陆上检波器地震数据的匹配、可控震源资料的最小相位化处理、不同类型震源所获地震数据的匹配处理等关键技术的试验处理,确定了有效而实用的处理流程:①对可控震源资料进行最小相位化处理,以炸药震源激发的数据为标准对其做匹配滤波处理,使得可控震源资料与炸药激发的资料获得最佳匹配;②将两种震源激发的数据做CMP道集分选,再进行地表一致性振幅处理和地表一致性反褶积处理。利用上述处理流程最终获得了用户满意的偏移剖面。更多还原

【Abstract】 Based on the characters of seismic data ac quired in Sudan swampy area, and in combination with available processing system for BGP seismic data processing center in Sudan, the paper determined effective and practical processing flow through the experimental processing of such key techniques as match of seismic data of hydrophone with land geophone, minimum phase processing of vibroseis data and matching processing of seismic data acquired by different type of sources:①minimum phase processing of vibroseis data,taking the data acquired by blasting powder source as standard to do match filtering processing, making the data acquired by vibroseis and blasting powder a-chieve optimal match;②sorting CMP gathers from data acquired by two sources,then the surface-consistent amplitude processing and surface-consistent deconvolution processing are carried out. Using abovementioned-processing flow can finally achieve the migrated sections that are satisfactory to the users.更多还原
