Description
К верхней резьбе патрубка 7 присоедин ютс трубы, и пакерное оборудование снускаетс в скважину. При этом обратный клапан 11 пакера закрыт и жидкость поступает в трубы через отверсти 9 в цилиндре и отверсти в муфте 3, отжима манжету 4. После достижени места установки в трубы заканчиваетс жидкость. Манжета 4 под действием перепада давлений прижимаетс к стенке цилиндра 2, поршень со штоком 1 перемещаетс вверх, а цилиндр 2 - вниз. Конусы сжимают 19 и пакер уплотн етс в скважине. После этого шлипсы раскрываютс и заклинивают конусы в обсадной колонне скважины.Pipes are attached to the upper thread of the pipe 7, and the packer equipment is discharged into the well. At the same time, the check valve 11 of the packer is closed and the liquid enters the pipes through the holes 9 in the cylinder and the holes in the sleeve 3, pressing the cuff 4. After reaching the place of installation in the pipes the liquid ends. The cuff 4 is pressed against the wall of the cylinder 2 by the pressure differential, the piston with the rod 1 moves up, and the cylinder 2 moves down. The cones compress 19 and the packer is compacted in the well. Thereafter, the slips open and the cones jam in the well casing.
Фиксатор 13 удерживает ствол пакера от перемещени относительно щлипсов. При дальнейщем повыщении создаваемого инструментом осевого усили щпилька 10 разрываетс и инструмент отсоедин етс от пакера. После этого можно производить закачку жидкости под пакер или откачку жидкости из-под пакера. Дл откачки необходимо спустить колонну труб со щтоком дл открыти обратного клапана пакера.The latch 13 keeps the packer barrel from moving relative to the clips. As the axial force generated by the tool is further increased, the pin 10 is broken and the tool is disconnected from the packer. After that you can pump the liquid under the packer or pump the liquid out from under the packer. For pumping, it is necessary to lower the pipe string with the stem to open the packer check valve.
Применение предложенного пакерного оборудовани позвол ет значительно упроститьThe use of the proposed packer equipment allows to significantly simplify
ремонтные работы в скважинах, сократить врем установки разбуриваемых пакеров, повысить надежность их посадки и уллотнени , а также обеспечить безаварийное автоматическое отсоединение посадочного инструмента от пакера после посадки.repair work in wells, reduce the installation time of drilled packers, increase the reliability of their planting and packing, as well as ensure trouble-free automatic disconnection of the landing tool from the packer after planting.
