METHOD FOR CLEANING OF HEAVY OILS USING COORDINATION POLYMERS

The effect of synthesized composite materials BAF-1 and BAF-2 (conditional names) based on coordination polymers on improving the rheological properties of oil was studied. The mechanism of action of nanostructured coordination polymers was studied by X-ray and electron microscopic methods. These composite materials form non-valent compounds with self-construction and self-organization due to their porous structure. When interacting with oil, they are capable to destroy the asphaltene-resin-paraffin deposits (ARPD), which ensures their equal distribution in oil. In this way, oil recovery from wells increases, and ARPD are effectively washed out of cavitation zones that form in the pipeline, which in turn ensures the cleaning of oil reservoirs from oil and oil product deposits. The proposed composites are capable of solving many problems associated with ARPD, in particular, they improve oil recovery from wells, reduce the viscosity of heavy oils and increase the transportation of such oils, i.e. the technology based on the indicated reagents is multifunctional.
