I Изобретение относитс  к нефтедо&1вак1цей промлпленности, в частности к устройствам дл  ремонта обсад ной колонны в скважине. Известны устройство pj и способ 2J ремонта обсадных колонн. Наиболее близким к предлагаемому  вл етс  устройство дл  ремонта обсадной колонны, содержащее привод расшир ющей конус и про илыый патр бок з. Недостатком известного устройства  вл етс  мала  длина перекрываемого интервала из-за ограниченности рабочего хода поршн  привода. Цель изобретени  - упрощение тех нологии работ и увеличение длины пе рекрываемого интервала. Поставленна  цель достигаетс  тем, что устройство дл  ремонта обсадной колонны, содержащее привод, расшир кшщй конус и расшир емый патрубок, снабжено дополнительным расшир ющим конусом, размещенным внутри патрубка,выполненного с утолщенны м во внутрь концами,и св занным с основным. На 4мг . 1 показана схема устройства , привод не показан; на г.2отремонтированна  с помощью предлагаемого устройства обсадна  колонна . Устройство состоит из патрубка 1,внутри которого проходит шток 2 с верхним 3 и нижним 4 расшир ющиьшс  кону . Патру бок верхним концом упираетс  в упор 5, взаимодействующий с приводом. Расшир ющиес  конусы З.и 4 могут быть установлены на штоке 2 18,2 таК,чтобы одновременно расширить оба конца патрубка, или так, чтобы они проходили через концы патрубка поочередно „ В первом случае рассто ние между ними равно дпине патрубка, уменьшенной на длину первого конца;во втором случае рассто ние между концами увеличивают или уменьшают на длину первого конца. Устрорсство работает следующим образом . После спуска устройства в ремонтируемый интервал привод т в действие привод, который т нет вверх шток 2 вместе с расшир ющими конусаки 3 и 4. Последние, проход  через сужени  на концах патрубка расшир ют .внутренний диаметр концов до диаметра средней части патрубка . При этом наружный диаметр концов увеличиваетс  до внутреннего диаметра обсадной колонны. В результате ремонтируеьйт участок остаетс  между концаг«1 патрубка,которые прочно и герметично прижаты к стенкам обсадной колонны. Форма расшир емого патрубка и установка дополнительного расшир ющего конуса позвол ет сократить длину рабочего хода расшир к цего конуса до длины утолщенных концов расшир емого патрубка,тогда как в прототипе она равна,длине самого патрубка. Таким образом; длина рабочего кода расшир ющих конусов не зависит от длины расшир емого патрубка,поэтому последний может быть практически любой необходимой длины.I The invention relates to oil production & 1 production, in particular, casing repair devices in a well. The known device pj and method 2J repair casing. Closest to the present invention is a casing repair device comprising a cone expanding actuator and a sleeve side c. A disadvantage of the known device is the small length of the overlapped interval due to the limited stroke of the actuator piston. The purpose of the invention is to simplify the technology of work and increase the length of the overlapping interval. This goal is achieved in that the casing repair device, comprising a drive, an expanding cone and an expandable nozzle, is provided with an additional expansion cone located inside the nozzle, provided with thickened inside ends, and connected to the main one. At 4mg. 1 shows a diagram of the device, the drive is not shown; on c.2 a casing column repaired using the proposed device. The device consists of a nozzle 1, inside which a rod 2 passes with an upper 3 and a lower 4 expanding horse. The patra with its upper end rests against the support 5, which interacts with the drive. Expanding cones Z. and 4 can be mounted on the stem 2 18.2 such as to simultaneously expand both ends of the nozzle, or so that they pass through the ends of the nozzle alternately. In the first case, the distance between them is equal to the distance of the nozzle reduced by the length the first end; in the second case, the distance between the ends is increased or decreased by the length of the first end. The arrangement works as follows. After the device has been lowered into the repair interval, the drive is actuated, which does not have an upward stem 2 together with expansion cones 3 and 4. Lastly, the passage through the constrictions at the ends of the nozzle expands the inner diameter of the ends to the diameter of the middle part of the nozzle. In this case, the outer diameter of the ends increases to the inner diameter of the casing. As a result, the repair area remains between the end of the "1 nozzle," which are firmly and hermetically pressed against the walls of the casing. The shape of the expandable nozzle and the installation of an additional expanding cone can reduce the length of the working stroke expanding to its cone to the length of the thickened ends of the expandable nozzle, whereas in the prototype it is equal to the length of the nozzle itself. In this way; The length of the working code of the expansion cones does not depend on the length of the expandable nozzle; therefore, the latter can be practically any necessary length.
