在一个工区同时开展了浅层纵横波折射、纵横波微测井的野外勘探,并取得较为丰富的野外资料以及处理和解释成果。本文着重介绍野外采集方法及最终解释成果。在横波微测井观测过程中,灵活性地解决了一些施工难题,并取得了较为理想的资料。在对比纵横波折射和纵横波微测井所求数据的基础上,首次用地震方法获取了该工区浅水面的高程,并得出了一些有意义的结论。获得了低速带的纵横波速度,低速带的高程以及低速带的层厚度。通过对比微测井和小折射求得的速度,最终给出了整个工区的纵波及横波低速带校正值。
At the same time, field exploration of shallow longitudinal-shear wave refraction and longitudinal-shear-wave micro-logging was carried out simultaneously in a work area, and abundant field data and processing and interpretation results were obtained. This article focuses on field acquisition methods and the final interpretation. In the process of transverse well micro-logging observation, some construction problems are flexibly solved, and the ideal data are obtained. On the basis of comparing the data of longitudinal-shear wave refraction and longitudinal-shear-wave micro-logging, the elevation of the shallow water surface is obtained by seismic method for the first time, and some meaningful conclusions are obtained. The longitudinal and shear wave velocities of the low velocity belt, the elevation of the low velocity belt and the layer thickness of the low velocity belt were obtained. Comparing the velocities obtained from the micro-logging and the small refraction, the correction values of the longitudinal wave and the low-velocity zone of the transverse wave are given.
