摘　　要：采用三分量微测井技术调查地表岩性,可以获得纵、横波2种波场信息。描述了微测井资料采集,纵、横波波场分离处理以及初至时间的几何校正,计算出纵、横波速度,最后结合测区露头剖面对松散黄土岩性进行了划分。结果表明,纵、横波速度界面与地层界面对应良好,横波对岩性划分更为精细。Three-component micro-logging technique is used to investigate the surface lithology, and the information of P-wave and S-wave data can be obtained. The micro - logging data acquisition, the P-wave and S-wave separation process and the geometric correction of the first time are described. P- wave velocity, S-wave velocity are calculated. Finally, the outcrop profile of the loose loess is divided. The results show that the interface between the P-wave and S-wave velocity and the stratigraphic interface is well, and S-wave is more fine.
