介绍了VSP计算时间 -深度关系的原理 ,从深度测量、初至拾取、观测系统 3个方面分析了计算误差的来源 ,并提出了在野外采集和处理解释过程中应采取的预防和校正措施。
The principle of VSP calculating time-depth relationship is introduced. The sources of calculation errors are analyzed from three aspects of depth measurement, initial pick-up and observation system, and the precautionary and corrective measures should be taken in field acquisition and processing interpretation.
