中国西部山地地震资料非常复杂,地表静校正复杂和低信噪比是困扰处理人员的两大难题。本文在分析对比各种压制倾斜干扰的技术方法的基础上,提出采用静校正和叠前提高信噪比交互迭代的方法,有效地解决了这两个难题。对于各种干扰进行有针对性地压制与消除;在提高信噪比的基础上提高了资料的分辨率。
The seismic data of the mountainous areas in western China are very complicated. The complicated surface static correction and low signal-to-noise ratio are two major problems that plague the handling personnel. Based on the analysis and comparison of various technical methods for suppressing tilt interference, this paper proposes to solve these two problems by adopting static correction and pre-stack iterative method to improve signal-noise ratio. For a variety of interference in a targeted manner to suppress and eliminate; in improving the signal to noise ratio based on the improved data resolution.
