Item type:Article, Access status: Open Access , The usage of mathematical MLT model for the calculation of thermal filtration(2006) Danayev, Nargozy T.; Ahmed-Zaki, Darkhan Zh.During the research we used a well-known mathematical MLT model - Muskat-Leverett Thermal for the numerical calculation of the thermal filtration of a biphasic liquid in a porous space. The mathematical theory of thermal influence on filtration of the biphasic liquid for MLT model was offered by V.N. Monakhov and O.B. Bocharov. The influence of temperature on the character of liquid motion is possible through the change of viscosity and capillary properties of different liquid components which depends on their temperature and temperature of skeleton in a porous space. The characteristic feature of the thermal model of biphasic filtration is all equalizations which are necessary for making biphasic filtration, except the laws of Darcy and Laplas, are the results of saving laws of the continuous environment mechanics. In addition, a MLT model is technological in sense that for its description only the functions-parameters are used, which are defined experimentally. The computational analyses of the influence of thermal processes of joint motion of many-fazed liquids allows to describe the process of filtration of two and more liquids with different physical properties in a porous environment adequately, which represents a large interest in planning and development of gas and oil fields.
