This article is devoted to studying of problems, existence of a significant amount of gas-condensate deposits of Azerbaijan causes high prospects of use of condensate also as a thinner at pipeline transport high-viscosity flooded by the crude oil. Finds relevance of an assessment of influence of concentration and viscosity of a thinner – condensate on physical and chemical characteristics of petrowater condensate mixes at various temperatures and the modes of currents. It is well-known the facts that availability of the dispersed water in petrocondensate mix reduces efficiency of operation of pipelines. So, the increase in volume of water and raised viscosity leads to rise in price of transportation by petrowater condensate mix. Besides the high content of the connected water in mix causes intensive education by asfaltqamparafin postponed, increases oil hardening temperature. On it regular control for changes of noted parameters (degree of water content and density of mix) is of great importance. Considering the aforesaid, for an assessment of influence of the content of condensate on reophysics indicators transported bypass crude oil at various temperatures laboratory researches were conducted. On the basis of the obtained data on test various petrowater condensate mixes were offered empirical a formula for determination of their water content and density. The analysis showed that the offered empirical models in comparison with the rule of additivity yield more acceptable results from the point of view of practice and will well be coordinated with data experimental defined the distinguished parameters
