DEVELOPMENT OF ASYMPTOTIC METHODS FOR SOLVING THE TASKS OF OIL THERMOHYDRODYNAMICS
O.V. Akhmetova, A.I. Filippov

A brief history of the development of analytical methods for solving problems of non-stationary heat exchange of well fluid, among which are asymptotic, is considered. A scheme is given for the asymptotic method of «spatial-by-coeffi cient averaging », which makes it possible to find approximate solutions to the problems of conjugation of nonstationary heat exchange containing parameters depending on spatial coordinates.
Keywords: asymptotic method; application steps; variable coefficients; non-stationary heat exchange; well thermodynamics.
