APPROCHES TO MODELING PROCESS OF TRANSPORTING FUEL BY A FIELD MAIN PIPELINE IN CASE OF LEAKPROOFNESS

A problematic issue in the use of collapsible pipelines is the loss of the pumped product due to leakage of the pipeline line caused by accidents and damage. It is possible to reduce the amount of losses of the pumped product when using collapsible pipe- lines by reducing the time it takes to detect pipeline damage and eliminate oil product leaks. Various methods and techniques based on variable physical phenomena and principles and using various techniques for describing hydrodynamic processes during the outflow of oil and petroleum products are widely known and used to determine the coordinates of the leak location on the main pipelines of the oil and gas complex. However, for collapsible pipelines there are a number of design features and operating modes that require scientific and technical studies. For engineering evaluation, one of the methods can be classical mathematical modeling of the transportation process. The paper proposes a method for detecting leaks in a collapsible pipeline based on a mathematical and electrohydraulic description of the process of transporting fuels through a dismountable pipeline in caset of leakproofness using refined calculated dependencies of the hydraulic resistance coefficient.
