RESEARCH OF PHYSICO-CHEMICAL IMPACT ON THE RHEOLOGICAL PARAMETERS OF HIGH-PARAFFIN OIL

Abstract

The presented article is dedicated to the separate and joint effect of magnetic field and the new composition prepared in the ratio of Difron-4201 + BAF = 1:1 on the rheological properties of highly paraffinic, emulsion oil. The sample taken from well number 208 of field May 28 of SOCAR has been used as high paraffin oil. Separate and joint impact of the magnetic field and composition on the freezing temperature, effective viscosity and amount of asphaltene-resin-paraffin deposits of high-paraffin oil has been studied. It was determined that the combined effect of the magnetic field with the composition is more effective. Thus, while the magnetic field and composition reduce the freezing temperature of oil from +17 °С to + 4˚C and + 2 °С, respectively, the freezing temperature of oil drops to -2 °С during the joint impact. The effective viscosity of oil under the impact of the magnetic field is 0.66 Pa·s, under the impact of the composition it is 0.44 Pa·s, and during the joint impact it is 0.003 Pa·s. The impact of the magnetic field, composition and the combined impact of magnetic field with composition on the amount of paraffin deposits has been studied and their effect has been determined by “Coldfingertest” method. It has been determined that the effect of the magnetic field on paraffin deposits accumulated on the surface of the Coldfingertest is 52%, the effect of the composition is 74%, and the effect of the combined form is 90%.
