核磁共振地下水勘查的模拟退火反演
GROUND WATER DETECTION BY NUCLEAR MAGNETIC RESONANCE METHOD BASED ON SIMULATED ANNEALING INVERSION
【摘要】 简要地介绍了NMR找水的理论方法,分析了核磁共振找水对于不同含水层的正演计算方法,并用模拟退火反演方法对一维含水模型进行反演,给出了三个不同含水层模型的模拟退火反演效果图。经对比验证,该方法在技术上是可行的,在理论上给出了对NMR反演进行改进的可行性方法。
【Abstract】 The paper briefly introduces the theory of Nuclear Magnetic Resonance (NMR) and analyze its forward modeling and 1D inversion algorithms using the simulated annealing for layered aquifers. Then, the algorithms are verified by three models with various aquifers and the results show the feasibility and potencial application of the NMR data inversion in the ground water detection.
