利用直达波提取低速带参数进行静校正

THE RESEARCH OF THE METHOD FOR GETTING THE PARAMETERS OF LOW-VELOCITY ZONES BY USING DIRECT WAVE

摘要: 介绍了初至拾取方法和提取低速带参数的方法、原理及静校正的应用效果。在煤田地震勘探中，大部分激发井深都在低速带界面以下，用直达波求取低速带参数，既准确又经济。

Abstract: In coal seismic prospecting,the mejority of shot-hole are under the low-velocity zones. The Parameters of low-velocity zones can be obtained from direct wave and the statics of these parameters can be done. The method of picking up the primary waves, the principle and method of getting the parameters of lowvelocity zones and the effect of statics are introduced.
