摘　　要：苏里格地区表层介质疏松、厚度大、表层结构及岩性复杂多变,导致静校正问题严重,使得地震资料分辨率降低,严重影响成像的质量,给储层识别增加难度。为了提升储层识别能力,本文研究了一种基于曲时面的初至统计迭代静校正技术。Surface media in Surige area is loose,thick,complex and changeable in surface structure and lithology,which leads to serious static correction problems,reduces the resolution of seismic data,seriously affects the quality of imaging,and increases the difficulty of reservoir identification.In order to improve the reservoir identification ability,this paper studies an iterative static correction technique based on first break statistics of curved time surface.
