The article considers the influence of a number of external and internal factors, mainly temperature disturbances affecting the change in flow resistance at certain stages of development of oil fields operated for many years. It was found that with a decrease in temperature, the viscosity of oil increases as a result of the formation of asphaltene, resin-paraffin compounds. These associations deposit into the pores, causing a decrease in permeability, a decrease in the inner diameter of the lifting pipes, and an increase in hydraulic resistance. Although the resin was absorbed by the reagent after the nanostructured coordination polymer technique, an increase in oil viscosity was observed. To eliminate the problem, part of the waste of the alkaline diesel fraction included in the composite pumped into the well was replaced by condensate. At the same time, high efficiency was achieved.
