核磁共振方法在湖北某地找水的效果

EFFICIENCY OF GROUNDWATER DETECTION IN THE LACK WATER AREA BY NUCLEAR MAGNETIC RESONANCE METHOD

应用核磁共振技术找水是核磁共振技术应用的新领域，核磁共振找水是一种直接探测地下水的地球物理方法。介绍了是在贫水地区一个指定范围内探测地下水的例子。比较所做的三个核磁共振测点的工作结果，确定出含水情况较好部位；配合做了电阻率对称四极测深，其工作结果指示出一低阻区域，是地下水富集带。在设计的钻井位置钻探打出了优质地下水，验证了核磁共振找水方法的推断结果。在对核磁共振找水方法研究和实践的基础上，指出：核磁共振找水方法和其它的找水方法相比，具有分辨率高、效率高、投资小、见效快等优点，在工作中配合使用电阻率法勘探可以提高钻探成功率，这一点在探测和构造、破碎带、风化带有关的地下水时显得更为重要。

To utilize the Nuclear Magnetic Resonance (NMR) method in detecting groundwater is one of the new application areas of NMR technique. The NMR detecting groundwater is one of the geophysics exploration methods, and can directly detect ground water.This paper gives an example on detecting groundwater in a lack water area which is designated.To compare the result by NMR sounding on three positions,ascertained the better aquifer position.In addition the Vertical Resistivity Sounding (VES) shows a conductive zone,which is the accumulated water.The drilling successfully found good quality groundwater.The result validate the interpretation of NMR.Based on the research and practice on the NMR method,the paper indicates that this NMR method has the character of high resolving power,high effciency,low cost and good nesuet in comparison with other geophysical methods in the groundwater detection.To assist with the VES one can increase the successiveness nesuet in comparison,especially in detecting the groundwater that is relate to the structure,of ruptured zone and efflorescent zone.
