EXPRESS-METHOD AND APPARATUS OF PROTON MAGNETIC RESONANCE RELAXOMETRY FOR MEASUREMENT OF DENSITY AND MOLECULAR MASS OF OILS
Abstract
Performed the analysis of the calculation methods of mean molecular mass MM determination using density values. Experimentally determined the dependence of density r from proton spin-lattice Т1H and spin-spin Т2Н relaxation times of oil. Using obtained correlations calculated dependences of MM from relaxation times Т1,2Н. Examination by compare experimental and theoretical dependences ММ(Т2Н) showed, that relaxation times allows expressly determine ММ.
