Specification of oil leakage points based on the operation data of pipelines

The paper deals with the analysis of negative effect of the complications in the operation of oil pipelines on environment and the analytical specification of oil leakages from the pipelines as well. An empiric expression for the approximation of oil leakage due to the failures based on the ratio of corresponding losses considering the changes of combined characteristics of pump station and pipeline before and after the leakage is offered. The paper presents the calculations on the definition of leakage points based on the data of chronicality of oil leakages from the pipelines due to the failures and the changes of operation parameters; good results have been obtained. Thus, it is possible to specify the leakage sites in the reference point by the values of rate and pressure at the moment of leakage, although in the practice it is an approximate value.
