线性动校正方法检测炮点偏离设计点的原理及应用

The Application and Principle of Detecting the Deviated Source with LMO

在地震资料采集过程中,经常出现炮点偏离设计点的现象。因此,对当天采集的地震数据及时进行检查并作初步处理,实施现场质量监控尤为重要。本文详细分析了基于水平层状介质线性动校正方法识别炮点偏离设计点的方法原理,并结合实际地震资料,验证了该原理的正确性。

During seismic data acquisition,the deviated source often occurs.Therefore,it is important to implement on-site QC（Quality Control） by examining and pre-processing the seismic data timely.This paper analyzed the principle of detecting the deviated source with LMO method based on horizontal layered media in details,and verified the correctness of the theory combined with the actual seismic data.
