Description
Устройство дл ремонта обсадной колонны труб в скважине (фиг. 1) состоит из полого корпуса с последовательно установленными в нем силовыми гидравлическими цилиндрами, расположенными в гидроци- линдрах телескопически установленного в полости корпуса полого штока 1 с поршн ми , пластыр 3, дорнирующей головки Д, упорного патрубка 2, который телескопически установлен в нижней части полости кор- пуса и имеет секторы с зубчатой насечкой, один из которых Б расположен на внутренней поверхности в верхней части упорного патрубка, а остальные - последовательно в продольной плоскости на наружной повер- хности упорного патрубка на рассто ни х I один от другого, равных рабочему ходу поршней полого штока. Длина упорного патрубка должна быть не менее длины пластыр .A device for repairing a casing pipe string in a well (Fig. 1) consists of a hollow body with successively installed hydraulic power cylinders arranged in hydraulic cylinders telescopically mounted in the hollow body of a hollow rod 1 with pistons, plaster 3, dorning head D, the thrust pipe 2, which is telescopically mounted in the lower part of the body cavity and has sectors with a notched notch, one of which B is located on the inner surface in the upper part of the thrust pipe, and the rest are edovatelno in the longitudinal plane on an outer pover- ited thrust nozzle at distances I from one another equal to the stroke of the hollow piston rod. The length of the stop pipe must be at least the length of the plaster.
Упорный патрубок имеет узел его фиксации , выполненный с возможностью поочередной фиксации упорного патрубка на корпусе и полом штоке в виде секторов 4 с зубчатой насечкой, последовательно распо- ложенных в продольной плоскости на наружной поверхности полого штока на рассто ни х I один от другого, равных рабочему ходу поршней полого штока, дл фиксации упорного патрубка при рабочем ходе полого штока и сектора В с зубчатой насечкой, расположенного в нижней части полости корпуса с возможностью поочередного взаимодействи с секторами упорного патрубка при осевом перемещении корпуса.The thrust nipple has a fixing unit made with the possibility of alternately fixing the thrust nipple on the housing and the hollow stem in the form of sectors 4 with a notched notch, successively located in the longitudinal plane on the outer surface of the hollow rod at distances x i from one another, equal to the working to the piston stroke of a hollow rod, for fixing the stop pipe during a working stroke of a hollow rod and sector B with a notched notch located in the lower part of the housing cavity with the possibility of alternating interaction with sectors molecular nozzle by axial movement of the housing.
Корпус устройства крепитс в верхней части к транспортной колонне труб 5 дл спуска устройства в колонну труб 6. Секторы Б и В расположены в окнах 7 обойм 8, свободно перемещаютс в окнах и поджаты плоской пружиной 9.The housing of the device is attached in the upper part to the transport string of pipes 5 for lowering the device into the column of pipes 6. Sectors B and C are located in windows 7 of the sleeves 8, move freely in the windows and are preloaded by a flat spring 9.
Устройство работает следующим образом .The device works as follows.
На транспортной колонне компрессорных труб 5 устройство спускают к месту по- вреждени обсадной колонны 6. После спуска на заданную глубину в устройстве создают избыточное давление наземной насосной установкой. Рабоча жидкость по колонне труб 5 и каналам 10 полого штока поступает под поршни силовых гидравлических цилиндров.On the transport string of compressor pipes 5, the device is lowered to the site of damage to the casing 6. After descending to a predetermined depth, the device is pressurized with a surface pump unit. The working fluid through the pipe string 5 and the channels 10 of the hollow rod enters the pistons of the power hydraulic cylinders.
Поршни гидравлической донирующей головкой начинают перемещатьс , расшир пластырь 3 на длине I, равной ходу пор- шней силовых гидравлических цилиндров (фиг. 2), при этом секторы Б упорного патрубка вход т в зацепление с секторами 4, после чего давление сбрасывают и колонну труб 5 поднимают на высоту I хода поршнейThe pistons of the hydraulic dosing head begin to move, expanding the plaster 3 over a length I equal to the course of the piston of the power hydraulic cylinders (Fig. 2), while the sectors B of the stop pipe engage with the sectors 4, after which the pressure is released from the column of pipes 5 raise to the height of I stroke
п -,P -,
силовых гидравлических цилиндров (фиг. 3). При этом упорный патрубок 2 остаетс на месте,поскольку фиксируетс секторами В.power hydraulic cylinders (Fig. 3). In this case, the thrust pipe 2 remains in place, since it is fixed by sectors B.
Устройство готово дл совершени следующего рабочего хода с фиксированием пластыр . Количество рабочих ходов и соответственно количество секторов 4, а также число секторов на наружной поверхности упорного патрубка 2 определ ютс из соотношени L Г где п - количество рабочих ходов;The device is ready for the next working stroke with a fixing plaster. The number of working strokes and, accordingly, the number of sectors 4, as well as the number of sectors on the outer surface of the thrust pipe 2 are determined from the ratio L G where n is the number of working strokes;
L - длина пластыр ;L is the length of the patch;
I - величина хода поршней силовых гидравлических цилиндров.I - the stroke of the pistons of the power hydraulic cylinders.
Устройство обеспечивает установку пластыр в призабойной зоне и в обсадных колоннах малых типоразмеров (140,146 мм).The device ensures the installation of a plaster in the bottomhole zone and in casing strings of small sizes (140.146 mm).
