The degree of dispersity and the rheological properties of blended crudes from the Mangyshlak peninsula were studied. High-wax crudes from the Uzen' and Zhetybai fields and high-aromatic crudes from the Kalamkas and Karazhanbas fields were blended. The degree of dispersity was determined by laser correlation spectroscopy. Dynamic viscosity was determined under various shear stresses in a rotating viscometer. Variations of the ratios of components in the mixed crudes gave complex variations of viscosity. The transition from a highly aromatic crude to a waxy crude through a series of blends was accompanied by a change in the dynamic viscosity from monotonic to extremal.
