Description
Изобретение относитс к бурению и эксплуатации нефт ных и газовых скважин и может использоватьс при наращивании цементного кольца и создании экранов из тампонажных материалов за обсадной колонной с последующей герметизацией обсадной колонны металлическим пластырем в нефт ных, газовых и вод ных скважинах.The invention relates to the drilling and operation of oil and gas wells and can be used when building a cement ring and creating screens from cementing materials behind the casing with subsequent sealing of the casing with a metal patch in oil, gas and water wells.
Целью изобретени вл етс расширение технологических возможностей устройства путем обеспечени одновременного с установкой ремонтного патрубка тампонировани эаколонной зоны.The aim of the invention is to expand the technological capabilities of the device by providing plugging of the ecolonic zone simultaneously with the installation of the repair pipe.
На фиг. 1 изображено устройство дл ремонта обсадной колонны в скважине, спущенное в скважину, в момент закачки тампонирующего материала; на фиг. 2 - то же, при установке пластыр .FIG. 1 shows a device for repairing a casing string in a well, lowered into a well, at the time of injection of a plugging material; in fig. 2 - the same when installing the patch.
Устройство дл ремонта обсадной колонны в скважине состоит из кор 1, служащего дл опоры устройства на колонну, гидравлического домкрата в виде корпуса с последовательно установленными в нем гидроцилиндрами 2 с герметичными перегородками 3 между ними. В корпусе телескопически установлен полый шток 4 с поршн ми 5, расположенными в гидроцилиндpax , и радиальными отверсти ми А дл св зи полости штока с полост ми гидроцилиндров . Радиальные отверсти А перекрыты в исходном положении герметичными перегородками между цилиндрами. В нижней части полого штока установлена гидравлическа дорнирующа головка 6.A device for repairing a casing string in a borehole consists of a core 1, which serves to support the device on a column, a hydraulic jack in the form of a body with successively installed in it hydraulic cylinders 2 with hermetic partitions 3 between them. A hollow rod 4 with pistons 5 located in hydraulic cylinders and radial openings A for connecting the cavity of the rod with the cavities of hydraulic cylinders is telescopically mounted in the housing. The radial holes A are closed in the initial position with hermetic partitions between the cylinders. A hydraulic dorning head 6 is mounted in the lower part of the hollow rod.
Между корпусом и гидравлической до- рнирующей головкой расположен ремонтный патрубок 7. В нижней части полого штока под гидравлической дорнирующей головкой установлен с возможностью ограниченного осевого перемещени цилиндрический перекрывателъ 8 с фрикционным фонарем, а под цилиндрическим перекры- вателем в полом штоке выполнены радиальные отверсти 9 дл циркул ции в исходном положении тампонажного материала. В верхней части полый шток 4 жестко св зан с транспортной колонной труб (насосно- компрессорными трубами) 10.A repair nipple 7 is located between the housing and the hydraulic trailing head. In the lower part of the hollow rod under the hydraulic dorning head there is a limited axial movement of a cylindrical locking device 8 with a friction lamp, and under the cylindrical locking device in the hollow shaft there are radial holes 9 for circulating in the initial position of the grouting material. In the upper part, the hollow rod 4 is rigidly connected to the transport column (tubing) 10.
Устройство дл ремонта обсадной колонны в скважине работает следующим образом .A casing repair device in a well operates as follows.
После спуска его на транспортной колонне труб в скважину радиальные отверсти 9 располагаютс напротив зоны нарушени обсадной колонны. Открываютс радиальные отверсти 9 перемещением устройства вниз. В исходном положении радиальные отверсти А перекрыты. При таком расположении радиальных отверстий А и открытых радиальных отверсти х 9 производитс закачка тампонажного материала в зону нарушени обсадной колонны и задав- ливание его за обсадную колонну.After lowering it on the transport string of pipes into the well, the radial holes 9 are located opposite the casing disturbed zone. The radial holes 9 are opened by moving the device down. In the initial position, the radial holes A are blocked. With this arrangement of the radial holes A and the open radial holes 9, the grouting material is pumped into the area of the casing disturbance and crushed by the casing.
После закачки и продавки тампонажного материала располагают ремонтный патрубок напротив зоны нарушени обсадной колонны. Перемещением устройства вверх перекрывают радиальные отверсти 9 цилиндрическим перекрывателем 8. Затем в устройстве создают рабочее давление, при этом корь 1 входит в зацепление с колонной .After injection and displacement of the grouting material, a repair nipple is located opposite the casing disturbance zone. Moving the device upwards, block the radial holes 9 with the cylindrical shutter 8. Then, the device creates a working pressure, and the bark 1 engages with the column.
Перемещением транспортной колонны труб вверх прот гивают гидравлическую до- рнирующую головку внутрь ремонтного патрубка , отверсти А штока выход т из герметичных перегородок и жидкость поступает в цилиндры гидравлического домкрата (фиг. 2). При дальнейшей закачке жидкости гидравлический домкрат прот гивает головку б внутри ремонтного патрубка на длину, равную ходу поршней. Одновременно осуществл ют подъем транспортной колонны труб на величину хода поршней домкрата. Оставшуюс часть ремонтного патрубка расшир ют прот гиванием головки 6 с помощью транспортной колонныBy moving the transport string of pipes upward, the hydraulic locking head is pulled inside the repair nozzle, the stem holes A come out of the hermetic partitions and the liquid enters the cylinders of the hydraulic jack (Fig. 2). Upon further fluid injection, the hydraulic jack pulls the b-head inside the repair pipe for a length equal to the stroke of the pistons. At the same time, the pipe transport column is lifted by the stroke of the jack pistons. The remaining part of the repair pipe is expanded by the head 6 being pushed through the transport column.

После расширени и прижати ремонтного патрубка по всей длине устройство спускают в крайнее нижнее положение, открывают радиальные отверсти 9, промывают скважину до вымываpipes and talevy system. After expanding and pressing the repair pipe along the entire length, the device is lowered to the lowest position, the radial holes 9 are opened, the well is washed before washing
