Emphasis is placed on an inseparable triad: model -- algorithm -- computer code. An analysis of new and traditional filtration problems from the point of view of both their numerical implementation and the reproduction of one or another technological characteristics of the processes under consideration is given. The basic principles which underlie the construction of efficient numerical methods taking into account the filtration problems are discussed: non-evolutionary nature, degeneration, strongly varying coefficients, the (temporal) duration of the processes involved, etc. Also attention is paid to the splitting method in terms of the physical processes involved, the method of fictitious domains and the method of front separation in grid solution. A modular analysis is performed with computational algorithms, making it possible to set up simultaneously the structure of the algorithms themselves and the structure of programs to implement these algorithms on a computer. In conclusion, the author discusses issues concerning the possibility of constructing a model of an oil deposit on a computer.Contents: Basic Notions of Multiphase Incompressible Fluid FiltrationFormulation of the Two-Phase Incompressible Fluid Filtration Problem with Capillary ForcesTwo-Phase Incompressible Fluid Filtration Problems without Taking into Account Capillary ForcesBuckley-Leverett ModelTwo-Phase Filtration ModelsMethod of Fictitious DomainsDifference Schemes for Model Linear Filtration ProblemsElliptic ProblemDifference Schemes for Model Linear Filtration ProblemsParabolic ProblemDifference Schemes for Model Linear Problems of Two-Phase Incompressible Fluid Filtration in Terms of PotentialsDifference Schemes for Two-Phase Incompressible Fluid Filtration ProblemsSplitting Method in Terms of Physical Processes in Two-Phase Incompressible Fluid Filtration ProblemsDiscontinuity Localization in Solutions of Difference EquationsTechnology of Computational Experiment in Filtration ProblemsComputer-Assisted Model of an Oil DepositReferencesReadership: Applied mathematicians and computer scientists.
