Целью статьи является максимизация добычи нефти путем формирования эффективных решений по вводу в разработку трудноизвлекаемых запасов месторождения Т. Основную часть трудноизвлекаемых запасов (52 %) занимает пласт ЮС2, ввод которого в разработку запланирован на 2022 год. ЮС2 характеризуется низкой проницаемостью 0,6 мД, нефтенасыщенная толщина составляет 9,8 м. Основным методом разработки трудноизвлекаемых запасов месторождений Западной Сибири является горизонтальное бурение с многостадийным гидроразрывом пласта. В статье проводится анализ конструкций скважин с разной длиной горизонтального ствола и с разным количеством портов ГРП. Выполнены расчеты стартовых дебитов и профилей добычи для различных вариантов скважин для типовой скважины. Оценка оптимального решения проводилась с использованием комплексного критерия NPV и накопленной добычи.

The article objectives are developing hard-to-recover reservoirs and how to maximize oil production by formulating effective solutions for putting hard-to-recover reserves. US2 is planned to be put into development in 2022 and contains 52% of the initial reserves of the entire field. US2 reservoir complicated by low permeability 0.6 mD, saturated intervals are 9.8 m. The main method of developing hard-to-recover reserves in Western Siberia fields is horizontal drilling with multi-stage hydraulic fracturing. As a matter of course, well designs were analyzed with different lengths of horizontal shaft and with a different number of hydraulic fracturing ports. Calculations of starting flow rates and production profiles for various well options for a typical well have been performed. The optimal solution was evaluated using the complex parameter NPV and cumulative production.
