摘要

Method to determine a property of the geological formation from measurements of nuclear magnetic resonance and method to determine a property of geological formations surrounding a fUro pit ".Method for the determination of a property of a geological formation from measurements of magnetic resonance imaging includes applying functions of suppression to spin echoes in at least one groupsTo measurements of "burst" to produce a data set of "burst" modified.The functions of suppression to suppress the contribution of echoes - sipn with correction of polarization is not negligible; reversing the data set of "burst" modified and at least one set of M.Editions of echoes - pin pattern to produce a distribution of parameter of nuclear magnetic resonance.The at least one set of measurements of the spin echo pattern and the at least one set of measurements of "burst" being purchased on a sample of the geological formation, and compute the ownership of the formau00e7u00e3From the geological distribution of parameter of nuclear magnetic resonance.The parameter of magnetic resonance imaging includes at least one selected from relaxation time longitudinal, transverse relaxation time.A comparison of longitudinal relaxation time for the transverse relaxation time and diffusion constant.
