FIELD: physics. ^ SUBSTANCE: application: for survey of wells with the help of nuclear magnetic resonance. It consists in the fact that multiple measurements are carried out by method of nuclear-magnetic resonance (NMR) of nuclear spins system, NMR-data is registered, received in every of multiple NMR measurements, multidimensional multiplicity of data is calculated by execution of reverse transformation process on NMR-data, which does not depend on preliminary knowledge about the area, including determination of fluid response from three-dimensional measurement according to equation where: tau1, tau2, tau3 - three parameters of data registration, which characterise specific measurement; f(i,j,k) - amplitude of component i, j, k in three-dimensional distribution (i.e. every distribution corresponds to specific property), H(tau1, tau2, tau3; i, j, k) - response of this component to measurement, which is preset by parameters tau1, tau2, tau3; delta - accidental noise, at that response H(tau1, tau2, tau3; i, j, k) is determined at every value of i, j, k for every echo-signal (or, in case of compression with application of windows, for every sum of window echo-signals). ^ EFFECT: increase of validity of values that characterise composition of fluid. ^ 22 cl, 3 tbl, 7 dwg |
