金属矿转换波地震勘查技术模拟
|
摘要
结合金属矿体地震地质数学模型,对多波多分量地震勘探的数据采集和资料处理方法进行了探讨和研究,主要针对多波资料的分离、去噪、共转换点道集选排、动校叠加、偏移等特殊技术进行了处理试验。在无法得到有效反射纵波资料的地区,可尝试采用转换波地震勘探方法技术;也可利用多波多分量地震勘探分析纵、横波速度以获得较多的岩性参数,降低多解性。模拟研究结果对今后开展金属矿转换波地震勘探方法技术的应用与研究有一定的借鉴作用。
With the development of converted-wave exploration technology,multi-wave multi-component seismic exploration methods have been applied more widely.According to the metal model research,the receiving and processing method of multi-wave and multi-component seismic data is discussed and studied in this paper,mainly aiming at such special technologies as separation and noise reduction of multi-wave data,common conversion point gathering,NMO and migration method.The data receiving methods and processing techniques are of great significance for further application of converted-wave seismic techniques to metal ore body exploration.
