The purpose is to increase the reliability of repair of the external column. For this, the expansion cone (RK) 4 is made at the top of the pulley. The base diameter of the RC 4 is smaller than the internal diameter d located on the RC 4 of the nozzle 1 in the working position by no more than the value determined in accordance with the dependence; Ad / d 5.7368 sin2 1.5 ", where Ad is the increment of the internal diameter of the pipe 1 in the working position above the base diameter of the RK 4, m. The RK 4 moves by means of a hydraulic actuator 9 connected by a rod 5 to the RK 4. the hydraulic actuator 3 its pistons move upwards and through the stem of 5 tons of chickpeas - eepv PK 4 Passage through pipe 1, RC 4 expands it to press against the walls of the casing and seals the crack 6 in the casing 2 or C / t
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
