Urgent requirement of oil-industry laboratories - is possibility for express-analysis of nano level physical-chemical parameters (PCP) of oil disperse systems (ODS): interproton distances (~ 0.15 nm) in water droplets dispersed in emulsions of oil (~ 0.26 nm), pollutions of soils and waters. Method of pulse nuclear magnetic resonance relaxometry (NMRR) has great opportunities over others - nondestructive and noncontact, short time of measurement.

For the NMRR measurements in Construction Bureau of Resonance Complexes Ltd. we have designed portable, easily transported relaxometers NMR NP [1,2] (fig.1) with weight less, then 12 kg, power supplied from accumulator and connected with Notebook through LPT-port (fig.1) and USB-port. Relaxometers are used for measurement of interproton distances, relaxation times and proton populations and express-analysis of PCP. It has no analogues. In Kazan State University NMR NP-2 is used for educational process. They does not need sample preparation. Time of measurement – less, 2 minutes. Sensibility К = ν²D³ [МHz²см³] = 2700-4150 МHz2см³ is near to “Minispec pc120” (Bruker, Germany).

Crude oils emulsions are formed previously during the oil mining and changing conditions in an oil-well. Interproton distances and so the size of droplets is affected by energy dissipation as well the coalescence. So we are faced with a necessity to control this parameters.

This problems we tried to solve using Constructed by us on-line explosive and fire safe NMR-analyser (fig.2) [3,4], which was tested in real conditions of oil-mining plant in “Tatneft” company and also can be used for determination of physical-chemical properties of crude oil: water content in the range 4 - 100% with standard deviation S = ± 1.5%, gas content in the range 6 - 94% (error ±6 %), droplets sizes distribution in the range 1000-15000 nm.
