地震反射波CDP叠加技术在台山核电海域花岗岩孤石探测中的应用

摘要

介绍海域地震反射波多次覆盖CDP叠加技术,阐述海上单道地震与CDP叠加技术的差别,从方法原理、震源选择、观测系统等方面分析探测小尺寸异常体的关键技术,通过钻探验证说明该技术在探测风化残留体中孤石的良好效果。%The multichannel CDP stacking technology in marine seismic reflection is presented,the difference between the CDP stacking technology and the single-channel seismic detection technology are described,and the key technologies in the detection of small geological bodies are analyzed in terms of principle,seismic source selection and observation system.The results of the drilling investigation show that the mentioned technology is satisfactory in detecting the boulders in weathered granite.
