- Abstract
The process of oil leakage in case of seal failure of long operated underground oil pipeline is suggested. For diagnosing of leakages of oil and their liquidation the problem of regularities of oil filtering in the porous medium as a result of appearance of a source is solved. Oil filtering in the soil is described by the linear equations of Darci. The task is reduced to determination of influence of a point source on process of filtering by means of Dirac function. By means of mathematical transactions the equation allowing to predict change of pressure in the porous medium in time due to growth of the filtrational resistance caused by oil leakage from the pipeline is obtained. For determination of expense of a leakage it is suggested to use iterative method which assumes time splitting of leakage into discrete time periodsΔt , during each of which leakage flow can be considered as a constant. For the end of intervalΔt the size of pressure of external resistance to the expiration is predicted and the leakage expense is determined. The results obtained have practical value for forecasting of oil leakage expenses from the underground oil pipeline in time taking into account soil resistance.
