The article is devoted to the selection of optimal solvents for the removal of asphaltene-resin-paraffin deposits. The efficiency of various solvents in relation to asphaltene-resin-paraffin deposits (ARPD) of the Ozen deposit is considered. According to the results of the experiments, it was revealed that the most effective composite solvent is a composition containing 50% of the gasoline fraction and 50% of the kerosene fraction. This compositional composition for 5 hours showed a loss of mass of deposits of 97.7%, a dissolving capacity of 93.5 g/cm3. The effectiveness of the compositional composition is confirmed by the paraffinic type of deposits, which is explained by the high content of paraffins in the oil composition of the Ozen field. Aromatic solvents showed a relatively low dissolving power compared to aliphatic solvents, which also confirms the low content of resins and asphaltenes in the ARPO composition.
Keywords: asphaltene-resin-paraffin deposits, solvent, asphaltenes, paraffins, resins.
