Технология термохимического стимулирования добычи нефти и битумов с уменьшением количества воды в нефтяном пласте

Технология термохимического стимулирования добычи нефти и битумов с уменьшением количества воды в нефтяном пласте

Abstract

An oil recovery technology using binary mixtures (BMs) is compared with the leading technologies currently being used around the world: hydraulic fracturing (hydrofrac) and steam-assisted gravity drainage (SAGD). The key advantages of the thermochemical BM technology as a resourceand cost-efficient one are demonstrated. It is suggested to improve the hydrofrac and SAGD efficiencies by heating the formation by the heat produced in the binarymixture reaction zone. Metallothermic reactions of new highly energetic BMs and their potential for stimulation of natural bitumen production, heavy oil hydrocracking, and reduction of water cut are discussed. The prospects of the thermochemical BM technology are evaluated in terms of energy and cost efficiencies.

Проведено сравнение технологии добычи нефти с использованием бинарных смесей (БС) и применяемых в мире ведущих технологий: гидроразрыв пласта (ГРП) и паровая технология прогрева пласта (SAGD). Выявлены основные преимущества технологии БС как ресурсосберегающей и экономически выгодной. Предложено усовершенствование технологий ГРП и SAGD путём разогрева пласта теплом химических реакций бинарных смесей. Рассмотрено применение новых высокоэнергетических растворов БС на основе металлотермии и их вклад в стимулирование добычи битумов, гидрокрекинг нефти и уменьшение обводненности продуктивного пласта. Дана детальная оценка энергетических и финансовых возможностей БС.
