地面核磁共振方法在马海钾矿区卤水勘查中的应用效果分析

Analysis of the Application Effect of the Surface Nuclear Magnetic Resonance Method in the Brine Exploration of the Mahai Potash Mine

摘要: 马海钾矿区位于柴达木盆地台坳陷中，钾矿区内卤水绝大部分为晶间卤水和孔隙卤水。地面核磁共振物探方法在该区具有物性前提，为合理布置勘探工程寻找卤水提供依据。地面核磁共振方法在该区的应用，取得较好的效果。本文在简要介绍地面核磁共振方法原理的基础上，以马海钾矿区卤水勘察为例，着重对该方法的资料解释和应用效果进行了分析讨论。

Abstract: The Mahai Potassium Mining Area is located in the basin of the Qaidam Basin. Most of the brine in the potash mining area is intercrystalline brine and pore brine. The surface nuclear magnetic resonance geophysical method has a physical property premise in this area, and it provides a basis for the reasonable arrangement of exploration projects to find brine. The application of SNMR method in this area has achieved good results. Based on a brief introduction of the principle of the surface nuclear magnetic resonance method, taking the brine exploration in the Mahai potash mine area as an example, this paper focuses on the analysis and discussion of the data interpretation and application effect of this method.
