Acquisition footprints generated during the marine seismic streamer construction have a great impact on fine structural interpretation and description of reservoir properties. Residual static correction can effectively attenuate the influence from the acquisition footprints and improve image quality of the seismic profiles. In this paper, the principle of residual static correction and the method to suppress the acquisition foolprints are described briefly. An application of the residual static correction using marine seismic data shows that the residual static corfection plays an effective role in the attenuation of acquisition footprints.%在海上地震拖缆施工中产生的采集脚印,对地下精细地质构造解释和储层特征及物性的描述和刻画均影响甚大.剩余静校正可以有效衰减采集脚印带来的影响,大大提高地震剖面成像质量,进而真实地反映地下深部地质构造特征,为油气勘探开发部署及油气地质综合研究提供高质量的地震剖面.文章阐述了剩余静校正及其衰减采集脚印的原理,并以南海A工区地震资料处理为例,论证了应用剩余静校正方法在海上地震数据处理中衰减采集脚印的有效性和可行性.
