摘要
在炸药震源激发的地震勘探作业中,激发井的深度准确与否是获取可靠地震资料至关重要的一环,但是井深的准确测定却一直缺乏科学有效的方法。本文介绍了一种新的基于金属导线电阻来测试地震激发井深的方法及配套设计的新型被覆线(炮线)——在专用炮线外附着一条专用测试线,随炸药下井,通过测量测试线的电阻,来计算测试线的长度,从而确定激发井的深度。这种方法比较方便实用地解决了困扰物探界多年的在野外精确测量物探井深的问题,成本不高、方法简便、非常实用,值得推广。
In dynamite source seismic exploration,the depth of well is the key data to obtain reliable seismic data from the crucial link,but how to get the accurate well depth has been lacking scientific and effective method for long time.This paper introduces a new kind of method which based on metal lead resistance test and supporting design new coating line(gun line).This new method not only can save cost but also is very simple and easy for application.Field operation proved that this method solved the problem of measuring the well depth which troubled the geophysical industry for many years.
