电法勘探在新疆水文地质勘查工作中的应用

摘要

从物探方法在新疆干旱及半干旱地区水文地质勘查的应用角度较全面地论述了应用前提和使用效果.提出了使用电阻率参数快速在咸水分布区圈定淡水分布靶区的经验公式,总结出了使用直流激发极化法探测水位的方法,就瞬变电磁法消除浅部勘探盲区的技术方法进行了探讨.基于CSAMT电阻率参数,对电阻率断面与反射系数断面进行了对比分析研究,认为后者较前者在电阻率异常的反映方面具有较好的收敛性.%This paper discusses the application premise and application effect of geophysical prospecting method in the application of hydrogeological exploration in arid and semi arid areas of Xinjiang.The use of rapid resistivity parameters in the empirical formula saline water distribution area,summed up the method of using DC induced polarization method for detecting water level,the method to eliminate the shallow exploration area by transient electromagnetic method is discussed.Based on the resistivity parameter of CSAMT,the resistivity cross section and reflection coefficient cross section are compared and analyzed.The latter is better than the former in resistivity anomaly reflection.
