CHANGE IN THE RHEOLOGICAL PROPERTIES OF HIGH-PARAFFIN PETROLEUMS UNDER THE ACTION OF VIBROJET MAGNETIC ACTIVATION
Yu. V. Loskutova, I. V. Prozorova, N. V. Yudina, S. V. Rikkonen, and V. A. Daneker UDC 662.276.7 The influence of the method of vibrojet magnetic activation on the rheological properties of high-paraffin petroleums has been investigated. The maximum decrease in the rheological characteristics of the petroleums was obtained in 20-min vibrojet treatment. It has been noted that the maximum effect of vibroaction is observed for petroleums with a higher-than-average content of paraffins. The role of the magnetic component contributing to the decrease in the congelation point and the amount of the basic sediment in the petroleums under study has been shown.
