The need to increase the capacity of the pipelines is increasing with the growth of oil and gas production in Russia. Russian and foreign scientists, who carry out numerous experiments and develop additives to oil and petroleum products that reduce hydraulic resistance and head loss from friction in the near-wall area of the pipeline, are working to solve the problem of oil pipeline capacity [1]. This paper considers the actual task of increasing the throughput capacity of oil product pipelines by the use of antiturbulent additive “CDR” and “M - FLOWTREAT” [2]. In the course of solving the task: an analytical review of methods to increase the throughput capacity of pipelines was carried out; a mathematical model of the additive effect on the conditions of oil flow in the pipeline was constructed; the effect of the additive on hydraulic resistance and oil flow velocity was investigated; a comparative assessment of the effectiveness of different additives on the throughput capacity of oil pipelines was given; the optimal concentration of the antiturbulent additive was selected [3]. The mathematical model proposed in this work, taking into account hydraulically smooth pipes and limitation, gives good results of capacity increase of up to 20%. Also, during the research it was found that the additive “M - FLOWTREAT” is more effective than “CDR” and from the point of view of capital investment is more favorable as to achieve the required performance, the amount of the additive is required less [4].
