Description

Изобретение относитс  к нефтедобыва ющей промышленности а именно к капитальному ремонту скважинThe invention relates to the oil industry, namely to workover of wells.

Цель изобретени  - повышение надежности ремонта обсадной колонныThe purpose of the invention is to improve the reliability of casing repair

На фиг 1 изображено устройство дл  ремонта обсадной колонны после спуска его в скважину, на фиг 2 - то же, в процессе работыFig. 1 shows a device for repairing a casing string after its descent into the well; Fig. 2 shows the same during operation.

Устройство дл  ремонта обсадной колонны включает патрубок 1, на верхнем торце которого расположено переходное кольцо 2 упирающеес  в гидропривод 3 В нижний конец патрубка вставлен расшир  ющий конус 4 св занный штоком 5 с гидро- приводом 3 предназначонным дл  перемещени  конус Конус выполнен с . г- лом при псришн 2Ь 60 и с д/ы 1 трог- ч новани  меньшим внутреннего дитметр патрубка в рабгнрм положении но CHJ/UJO чем на величину определ емую в СОШРОГ ствии со следующей члвиг ипостыоThe casing repair device includes a nozzle 1, the upper end of which has an adapter ring 2 abutting the hydraulic actuator 3 In the lower end of the nozzle an expansion cone 4 is inserted connected by a stem 5 with a hydraulic actuator 3 designed to move the cone Cone C. with glasm at psychosis 2L 60 and from d / s 1, the trogchny is smaller than the internal diameter of the nozzle in the working position but CHJ / UJO than by the value determined in the trick with the following iposti
