剩余静校正问题一直制约着地震资料分辨率的提高，进而影响到基于高分辨率地震资料的低幅度构造解释、岩性油气藏描述及储层物性研究。目前长垣油田已进入高含水后期，在剩余油挖潜研究中对地震资料的品质要求极高，剩余静校正的精度问题也越显突出。以长垣油田高密度工区地震资料处理为例，提出了一种基于低频模型道的剩余静校正方法。该方法利用振幅属性对地震道进行处理，形成振幅包络道集并构建低频模型道。采用互相关法求出地震道与模型道间的时移量，在地表一致性剩余静校正的基础上，进一步提高剩余静校正的精度。该方法在长垣油田高密度地震资料采集区取得较好应用效果。%Residual static correction problem has restricted the improvement of seismic data resolution, thus affecting the low am-plitude structural interpretation, lithologic hydrocarbon reservoir descriptions and reservoir property research, which based on high resolution seismic data. At present, Changyuan oilfield enters the later high water cut period. The quality requirement of seismic da-ta is extremly high in the remaining oil potential tapping research, and the issues of the accuracy of residual static correction is more remarkable. Taking the seismic data processing of high density work area in Changyuan oilfield for example, residual static correction method based on low frequency model trace was proposed. This method processed the seismic trace by amplitude attri-bute, formed amplitude envelope trace gather and established the low frequency model trace. The time shifting value of the seismic trace and model trace was determined by cross correlation method. On the basis of surface-consistent residual statics, the accuracy of residual static correction was further improved. This method is well applied in the high density seismic data collection area of Changyuan oilfield.
