Accelerating the development of hydrocarbon deposits, improving their technical and economic parameters, maximum
extraction of the products of the old oil and gas reservoirs require complex investigations involving mathematical tools.
In this paper we consider a mathematical model and software tool designed for the study of the filtration process a
mixture of the "oil-gas-water" in a porous medium for concrete practical recommendations and administrative
decisions. In the course of the numerical calculations were the main parameters of the process and its change ranges,
allowing to determine the operation of the reservoir depending on the length and capacity, also the number of wells and
production rates. The suitability of the developed algorithm and program for calculation of fields of pressure and
saturation are demonstrated, as well as field development indicators in the "Oil-Gas" systems, the "oil-water", "oil-gaswater". Results of numerical experiments on computer are presented as graphics.

Ускорение разработки углеводородных месторождений, повышение их технико-экономических показателей,
максимальное извлечение продуктов из старых нефтегазовых залежей требуют проведения комплексных
исследований с привлечением математических инструментов. В настоящей работе приведены описания
математической модели и программного средства для исследования процесса фильтрации смеси «нефть-газ-
вода» в пористой среде с целью принятия конкретных практических рекомендаций и управленческих решений.
В ходе проведенных численных расчетов установлены основные параметры исследуемого процесса и
диапазоны их изменения, позволяющие определять время эксплуатации пласта в зависимости от его длины и
мощности, числа скважин и их дебитов. Показана пригодность разработанного алгоритма и программы для
расчетов полей давлений и насыщенностей, а также показателей разработки месторождений в системах «нефть-
газ», «нефть-вода», «нефть-газ-вода». Результаты проведенных вычислительных экспериментов на ЭВМ
представлены в виде графических объектов.
