The critical analysis of current technology of onshore oil pipeline sections releasing from product for theirs repair are undertaken. Its shortcomings are established. The overview of modern plugging devices for oil pipelines sections localization while being repaired is provided, in particular the advantages and disadvantages of each considered one were analyzed. On the basis of this review an optimal plugging pig construction for oil pipeline sections isolation is proposed.The advantages and disadvantages of the proposed device are given. The necessity of simulation of plugging pigs motion in the pipeline is proved. The mathematical model of the plugging device movement along the main oil pipelines is formulated. The methodology of transient flow calculation during plugging pigs motion and stopping in the oil pipeline was proposed.
