Abstract
Operation of an oil pipeline with heating has its own specifics and is manifested, first of all, in the influence of pipeline heat exchange conditions with the environment on oil properties. Oil pipeline condition largely determines the technology, design and engineering solutions of oil pipeline, preservation of natural environment, as well as the choice of operating regimes. At the same time, it is required to actively manage the thermal condition of oil pipeline. Approximate formulas are known for solution of a great number of such tasks as prediction of heat and hydraulic regimes in conditions of changing operating parameters, which does not reflect the real situation accurately enough and does not satisfy the solution of the tasks set. The proposed forecasting methods most fully meet the temporal requirements.
