Abstract
Способ добычи углеводорода, такого как битум/сверхтяжелая нефть, из содержащего углеводороды пласта, в котором расположены верхняя нагнетательная скважина и нижняя продуктивная скважина, при этом способ содержит этапы предварительного подогрева области вокруг скважин и между ними путем осуществления циркуляции горячего растворителя через законченный интервал каждой из скважин до достижения достаточной гидравлической связи между обеими скважинами; нагнетания одного или нескольких растворителей углеводородов в верхнюю нагнетательную скважину при критической или более высокой температуре растворителя или растворяющей смеси, в результате чего побуждают смесь углеводорода и растворителя стекать под действием силы тяжести в нижнюю продуктивную скважину и доставляют углеводород на поверхность через нижнюю продуктивную скважину.
