Abstract
Изобретены способы выполнения техобслуживания и эксплуатации ствола скважины в системе стволов скважин, используемые для усовершенствованной добычи нефти. Совокупность стволов скважин бурят и перфорируют для приема текучих сред добычи из коллектора. Стволы скважин сообщаются текучей средой с эксплуатационной скважиной, пробуренной до глубины ниже отметки перфорационных каналов стволов скважин. Текучие среды добычи дренируются и собираются в эксплуатационную скважину для подачи на поверхность. Для подачи текучих сред добычи из эксплуатационной скважины можно использовать насос. Во время текущего ремонта и техобслуживания и эксплуатации текучую среду нагнетают в эксплуатационную скважину для безопасного удаления компонентов насоса. Текучая среда уравновешивается давлениями в сообщающихся стволах скважин, так что текучая среда не поднимается над перфорационными каналами в сообщающихся стволах скважин.
