Investigation of Electrohydraulic Effect on Physicochemical Characteristics of High-Resinous Oil “Karazhanbas”

In order to change the viscosity of high-resinous oil of the “Karazhanbas” field (Kazakhstan), the effect of electrohydraulic action on it was studied. The effect of adding an organic solvent xylene on the rheological properties of oil is investigated. A comparative study of the hydrocarbon composit...

description In order to change the viscosity of high-resinous oil of the “Karazhanbas” field (Kazakhstan), the effect of electrohydraulic action on it was studied. The effect of adding an organic solvent xylene on the rheological properties of oil is investigated. A comparative study of the hydrocarbon composition of oil before and after electrohydraulic impact was carried out by the method of gas chromatographymass spectrometry. Fragment composition of oil hydrocarbons before and after electrohydraulic treatment was determined by 1H and 13C NMR spectroscopy. It is shown that the conversion of heavy oil fractions to light ones begins with a five-time electrohydraulic impact. It is determined that 20‒25 electric discharge pulses are sufficient for the quantitative process of splitting hydrocarbons. It was found that the addition of xylene to high-viscosity oil leads to an increase in the conversion of hydrocarbons under electrohydraulic action. The content of paraffins and naphthalenes in high-viscosity oil is slightly reduced during electrohydraulic processing. In oil, after electrohydraulic action, a decrease in the proportion of protons of long alkyl terminal СН3-groups of hydrocarbons is observed, which indicates the process of decomposition of heavy oil fractions into light fractions.
