摘　　要：折射静校正和层析静校正方法是砂岩型铀矿地震勘探中2种常用的静校正技术。本文结合折射静校正与层析静校正2种方法对鄂尔多斯盆地北部砂岩型铀矿的地震资料进行静校正处理,综合对比2种方法的优缺点以及对该类地区的适用性。结果表明并非校正方法的算法越复杂解决问题的效果就越好,在满足折射静校正的条件下,使用折射静校正与层析静校正的混合静校正法处理所得的结果有较好的可靠性。Refraction static correction and tomographic static correction are two commonly used static correction techniques in seismic exploration of sandstone type uranium deposit.This paper summarizes and analyzes the key step and application condition of the two static correction methods.The practical application result of seismic data from sandstone type uranium deposits in the northern part of the Ordos Basin indicates that it's not that the more complex the algorithm,the better the problem-solving ability.The combination of refraction static correction and tomographic static correction can better solve the static correction problem on the premise of meeting the applicable condition of refraction technology.
