摘　　要：剩余静校正属于地震资料处理过程中的关键步骤,为了全面提高剩余静校正工作的开展质量,本次研究对静校正技术的原理以及目的进行深入分析,在此基础上,对地震资料剩余静校正工作开展过程中的关键步骤进行研究,为推动该领域的进一步发展奠定基础。研究表明:在进行地震勘探作业的过程中,由于获取的地震资料中干扰因素相对较多,因此,需要对地震资料进行静校正工作,尽管一次静校正可以在一定程度上提高地震资料的应用效果,但是地震资料中仍然含有大量的高频信息,剩余静校正工作主要是对数据资料中的高频信息进行处理。在对地震资料进行剩余静校正的过程中,需要做好地震资料叠前去噪以及偏移成像处理等多个方面的工作,进而全面提高地震资料剩余静校正技术的应用效果。Residual static correction is a key step in the process of seismic data processing.In order to comprehensively improve the development quality of residual static correction,this study makes an in-depth analysis of the principle and purpose of static correction technology.On this basis,it studies the key steps in the process of seismic data residual static correction,laying a foundation for promoting the further development of this field.The research shows that in the process of seismic exploration,due to relatively many interference factors in the acquired seismic data,static correction is required for the seismic data.Although one static correction can improve the application effect of seismic data to a certain extent,the seismic data still contains a lot of high-frequency information,and the remaining static correction is mainly to process the high-frequency information in the data.In the process of residual static correction of seismic data,it is necessary to do a good job in many aspects such as pre stack noise removal and migration imaging processing of seismic data,so as to comprehensively improve the application effect of residual static correction technology of seismic data.
