The article presents the results of the study of the influence of the composition and temperature of heating on the flow of the mixture of oil of West Kazakhstan/Mangyshlak/Aktobe fields (transported through the main pipeline «Kenkiyak-Kumkol») and oil fields of Kumkol group (treated with depressant); degree of rheological reduction depends on heating temperature, wax and asphalt-resin content and cooling conditions, and paraffin oils have an optimal heating temperature, where the heat treatment effect is greatest. This temperature is always higher than the melting point of the paraffins in the oil. At the same time, the most favorable conditions are created for dendritic crystallization of paraffin with the formation of the least stable structure. When heating high-frozen oil below the melting point of paraffins, there may be a sharp deterioration of the rheological parameters of the oil due to the formation of a solid fine-crystalline structure; the results of the physical-crystalline research are obtainedthe chemical and rheological properties of the oil mixture of ZKNS-Kumkol formulations 30-70 and 40-60% have shown that the negative effect from heating to 35 and 45oC must be taken into account when deciding on the use of oil heating technology to improve transmission modes, because this will lead to deterioration of rheological properties of oil and will reduce the effectiveness of the depressant additive (which is used to process the Kumkol component of the oil mixture). In order to improve the flow of the oil mixture ZKNS-Kumkolskaya can consider the possibility of heating the oil up to 55oC, or increasing the share of the West Kazakhstan component along with the absence of heating of the oil mixture (mixing of components at actual temperatures).
