Description
Summary:Petroleum produced in different regions and fields differ significantly in quality. The organization of pipeline transport of petroleum streams of a various quality produced in different geographic regions, according to a system with a complex topological structure, is possible only when controlling the quality of petroleum in traffic flows, in particular, controlling such property of petroleum as viscosity. Petroleum viscosity has a decisive influence on the performance of pumping and power equipment. The characteristics of the main petroleum pipelines depend on content’s viscosity. By influencing petroleum viscosity, it is possible to change the results of hydraulic calculations of main petroleum pipelines and pumping and power equipment without changing the equipment themselves, therefore, the task of changing the rheological characteristics of the pumped petroleum is timely. In this work, for the first time, thermal, super-high-frequency electromagnetic (SHF EM), high-frequency electromagnetic (HF EM) methods of treating the Siberian Devonian commercial petroleum and commercial petroleum of the Timan-Pechora province – Yaregskaya are studied. Both petroleum were exposed to thermal, high-frequency and super-high-frequency electromagnetic treatment on unique laboratory benches assembled at the Bashkir State University. As a result of the carried out studies, it was discovered that electromagnetic treatment affects the rheological properties of these petroleum in the temperature range corresponding to the operating temperatures of main petroleum pipelines. The most effective was the EM HF method of exposure. The relaxation time of the rheological properties of Devonian and Yaregskaya petroleum after EM treatment is 5 days, which is substantial compared to the currently popular thermal heating. The results of preliminary heat treatment with subsequent cooling on the Devonian and Yarega petroleum showed less efficiency compared to the results of electromagnetic treatment. When temperatures reach 30 degrees ...
