Numerical method of designing nuclear magnetic resonance logging device sensor
Optimal design of nuclear magnetic resonance (NMR) logging device sensor can enhance its detection performance and improve signal-to-noise ratio, and the accuracy of results from numerical method is absolutely critical for optimal design. In this paper, an eccentric NMR logging device static field distribution and radio frequency field distribution are simulated by the electromagnetic finite element method, and the influences of model shape, model size and element shape on simulation resultsdoi:10.7498/aps.61.149302 fatcat:nwyg6zumebaepalfaqqsee5i5q
