Модель растекания и поглощения нефти грунтами строится на основе уравнения неразрывности и закона фильтрации Дарси, а также уравнений состояния, учитывающих сжимаемость среды от давления. Область фильтрации - это граница между загрязненным нефтью грунтом и воздухом. Область фильтрации нефти снизу ограничена поверхностью почвы, а сверху - свободной поверхностью, уравнение которой заранее неизвестно и подлежит определению. Рассматривается сценарий загрязнения почв от точечного источника, в качестве которого выступает место разрыва трубопровода или скважина. Получены предельные и приближенные оценки радиуса разлива нефти в зависимости от различных типов подстилающих поверхностей и характеристик нефти, а также условий окружающей среды. Рассчитана и приведена динамика свободной поверхности нефти в зависимости от радиуса растекания. Сделаны оценки временной продолжительности фильтрации нефти грунтом в зависимости от фракций нефти и типа почвы. Была рассчитана толщина пленки и площадь разлива нефти при условии постоянной скорости истекания нефти, горизонтальности подстилающей поверхности и близости давления в среде к нормальному. Для численной реализации построенной модели были рассмотрены различные сценарии разлива нефти. При заданных значениях температуры воздуха, пористости почвы и скорости фильтрации рассчитан радиус загрязнения в зависимости от фракции нефти, времени с момента аварии до момента устранения течи, а также скорости истечения нефти.</p></abstract><trans-abstract xml:lang="en"><p>This article studies the elastic filtration oil drive of oil in a layer based on the estimation of risks of environmental oil pollution because of accidental releases. The model of oil spillage and resorption by the precoat is based on continuity equation and Darcy rule as well as on equations of state taking into account fluid compressibility due to pressure. Filtering area is a line between the precoat and air. Oil filtering area is limited by soil surface below and by free surface above, its equation is known beforehand and is to be defined. The case of soil pollution from the point source, which is the point of fracture of pipeline or borehole, is considered. Upper and approximate estimates of the oil pollution radius due to different types of underlying terrains and to oil characteristics as well as to environmental conditions. The dynamics of oil free surface depending on spillage radii is calculated and presented. The estimates of temporary duration of oil filtering by the precoat in terms of light ends and soil type are made. The thickness of the oil film and the square of the spill upon condition of constant speed of oil spillage, horizontal position of underlying terrain and the proximity of pressure to normal are determined. For the numerical implementation of the model different cases of oil spillage were considered. Under given values of air temperature, soil porosity and filtration speed the pollution radii according to light end, the time from the moment of accident till the leakage suppression and the speed of oil spillage was calculated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>модель растекания и поглощения нефти грунтами</kwd><kwd>упругий режим фильтрации</kwd><kwd>область фильтрации</kwd><kwd>пористость почвы</kwd><kwd>радиус и площадь загрязнения</kwd><kwd>фракции нефти</kwd></kwd-group><kwd-group xml:lang="en"><kwd>model of spreading and absorption of oil by soils</kwd><kwd>elastic filtration mode</kwd><kwd>filtration area</kwd><kwd>soil porosity</kwd><kwd>radius and square of pollution</kwd><kwd>oil fractions</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Polubarinova-Kochina P.Ya.
