发明名称 Method and computer program product for estimating true intrinsic relaxation time and internal gradient from multigradient NMR logging
摘要 A method and a computer program product for estimating the true intrinsic relaxation time T2 and the internal gradient Gint for a multi-frequency nuclear magnetic resonance imaging tool for well logging includes providing at least two frequencies in a plurality of echo trains, evaluating the signal decay in each echo train, quantifying the signal decay and correlating the signal decay to the internal gradient.
