Claims (9)

1. Инструмент для скважин, предназначенный для подачи жидкости к разным уровням внутри скважины, содержащий трубопровод, предназначенный для соединения посредством жидкости с нижним концом рабочей колонны, при этом упомянутый трубопровод имеет множество открытых в радиальном направлении выходных окон, отстоящих друг от друга в осевом направлении вдоль упомянутого трубопровода, множество выходных труб, каждая из которых одним концом подсоединена к соответствующему одному из упомянутых выходных окон, при этом каждая из упомянутых выходных труб имеет участок, который по длине фактически параллелен продольной оси упомянутого трубопровода.
2. Инструмент для скважин по п. 1, в котором упомянутый параллельный участок выходной трубы находится внутри упомянутого подводящего трубопровода, а упомянутый один конец выходной трубы, который подсоединен к выходному окну, образует выпускной конец упомянутой трубы.
3. Инструмент для скважин по п. 1, в котором упомянутый параллельный участок выходной трубы находится снаружи от подводящего трубопровода, а упомянутый один конец выходной трубы, который соединен с выходным окном, формирует впускной конец упомянутой трубы.
4. Инструмент для скважин по пп. 1, 2 или 3, в котором упомянутый подводящий трубопровод содержит: множество соединений, множество соединительных средств, при этом каждое из упомянутых соединительных средств предназначено для подсоединения двух смежных соединений друг к другу, причем в каждом из них имеется по меньшей мере одна из упомянутых выходных труб.
5. Инструмент для скважин по п. 4, в котором каждое из упомянутых соединений содержит отрезок трубы или отрезок фильтра скважины.
6. Инструмент для скважин по п. 4 или 5, в котором каждое из упомянутых соединительных средств содержит две детали, соединенные друг с другом и относительно подвижные между первым и вторым положением, а также тем, что по меньшей мере одна выходная труба открыта для потока, когда упомянутые детали находятся в первом положении, и закрыты для потока, когда детали находятся во втором положении.
7. Инструмент для скважин по п. 6, в котором упомянутые две детали каждого соединительного средства соединены друг с другом по резьбе, а также тем, что по меньшей мере одна выходная труба содержит канал через каждую из упомянутых двух деталей, при этом канал в одной из двух деталей совпадает с каналом в другой из двух деталей при нахождении в упомянутом первом положении, чтобы таким образом обеспечить поток через совпадающие каналы, и не совпадает с каналом в другой из деталей при нахождении во втором положении, чтобы таким образом блокировать поток через несовпадающие каналы.
8. Инструмент для скважин по любому из предшествующих пунктов, включающий в себя средства для закрывания упомянутой по меньшей мере одной выходной трубы при завершении подачи через нее упомянутой жидкости.
9. Инструмент для скважин по любому из предшествующих пунктов, включающий в себя средства для выгрузки упомянутого инструмента.
