摘要
针对惠州凹陷不同年度二维地震老资料存在的问题,提出了精细匹配处理方法。在匹配处理过程中,以精细频率补偿和精细振幅补偿为主要手段,结合震源信号反褶积处理、DMO处理、速度精细解释、叠前时间偏移处理以及去噪处理等手段,普遍突出了有效反射信息,提高了不同年度地震剖面之间的闭合精度。
In order to solve problems that exist in old 2D data acquired in various years from Huizhou sag, a technique of subtle matching processing is developed. During the matching processing, subtle frequency compensation and amplitude compensation are major methods, and several tools such as source signal deconvolution, DMO processing, refined velocity interpretation, pre-stack time migration and noise attenuation, etc. are combined. Thus effective signals are widely emphasized, and closure accuracy is increased among seismic sections acquired in various years.
