INTEGRATION OF DATA SEQUENCES OF ECHO SIGNALS IN TIME INTERVAL WITH DIFFERENT VALUES OF GRADIENT AND TIME BETWEEN ECHO SIGNALS

摘要

FIELD: physics; measurement.;SUBSTANCE: present invention pertains to the method of obtaining parametres of rocks using a nuclear magnetic logging device. During magnetic-nuclear measurements of spin echo with one or more differences, related to (i) time intervals between echo signals, (ii) static field gradient, (iii) polarisation time, or (iv) noise level, defined by diffusion coefficient of fluid, integration of measurement results of spin echo is not an easy task. Nevertheless, using a correction coefficient, that integration is possible and provides for better integration of rock properties.;EFFECT: increased efficiency of logging analysis and evaluating rock strata using combined signals, obtained from series of echo signals in different ranges of magnetic field gradient.;32 cl, 9 dwg
