【摘要】 在岩性油气藏勘探中,为了能有效地对岩性油气藏进行识别,考虑到高分辨率和高信噪比的处理会造成保真度变差,因此,采用相对保真处理方法.但是,忽略地震资料采集方式对地震处理的影响.为此,基于准噶尔盆地石东地区一条长8km的高分辨率数据采集试验测线,通过分析剖面的反射特征和频谱特征,分别对地震采集震源和观测方式对高分辨率高信噪比地震资料处理的剖面和对相对保真地震资料处理剖面进行了分析和讨论.炸药震源的处理剖面,无论单深井还是组合井剖面的目的层反射波组特征信息都比可控震源的处理剖面丰富;无论单深井还是组合并,接收道距不同,目的层反射波组纵、横向分辨率也不同.小道距(5m道距)接收,目的层反射波组纵、横向分辨率最高.更多还原

【Abstract】 Facing problem of high resolution or relative fidelity seismic processing in exploration and development of lithologic oil traps seismic data processing method effected by the method of acquisition is neglected.Therefore,one 8Km seismic profile from Shidong area in Zhunger Basin is processed by high resolution or the relative fidelity of seismic data processing method.To analyzing seismic profile and frequency of sand bed from high resolution、high S/ N ratio or relative fidelity seismic processing,seismic profile of single shooting (or pattern shooting) is better than seismic profile of vibrator shooting.Small geophone interval is higher resolution than big geophone interval in method of acquisition.更多还原
