With the development of reserves of oil and gas condensate fields, there is a need to study oil and gas condensate in order to assess the possibility of pumping them in the form of a combined mixture. To this end, laboratory studies and bench tests of oil and oil-gas condensate mixtures with different content of gas condensate in the composition have been carried out. Basing on the results of laboratory study, It is established that the increase gas condensate content in oil leads to changes in its physical properties and fire and explosion hazard indices. It is shown that the optimal gas condensate content is up to 10 wt. %. The results of the study of asphaltene aggregates stability has not reveal the incompatibility phenomenon when mixing oil and gas condensate. It`s been determined by bench tests that the addition of gas condensate to oil leads to reduce the hydraulic losses of flow specific energy and the rate of growth asphaltene-resin-paraffin deposits. Thus, the mixing of oil with a content gas condensate is practically useful in the operation of the main pipeline.

The regularities of changes in energy consumption to reduce the viscosity of highly paraffinic oil during processing in an installation based on a rotary impulse apparatus (RIA) are experimentally investigated. The decrease in oil viscosity during processing in RIA exceeds 40%. An increase in the amount of oil supply to the RIA makes it possible to reduce the specific energy consumption for its processing at the same relative value of the decrease in viscosity. Specific energy consumption decreases with an increase in oil consumption through the RIA according to the dependence close to the logarithmetic one.
