Abstract

Способ регулирования давления в кольцевом пространстве в скважине во время скважинной операции, которая содержит закачивание флюида вниз по колонне труб, расположенной в скважине, и извлечение флюида, который протекает обратно через кольцевое пространство в скважине и окружает колонну труб. Способ содержит определение заданного давления p, определение желаемого расхода qфлюида при его извлечении из кольцевого пространства в зависимости от заданного давления pи расхода при закачивании флюида в кольцевое пространство и формирование пути извлечения флюида из кольцевого пространства для достижения желаемого расхода при извлечении.
