Description

мыьаетс шар 6 верхнего клапана и устанавливаетс шар 7 ннжнего клапана в седло 8. Затем по колонне труб 12 подают газ, который , выход из насадок 4, замепдает жидкость из-под пакера 9 до нижнего уровп отвод пдего патрубка 2. Вытеснение жидкости из зоны перфорации можно контролировать по по влению газа на выкидной липни в затрубное пространство скважины. После этого производ т закачку жпдкости с абразивом в насосно-компрессорную трубу 12. Разруша стенку обсадной колонны ГЗ, жидкость с абразивом стекает вниз до нижнего конца патрубка 2 н манжеты 11, котора не дает возможности осаждатьс абразиву ниже манжета и по мере иакоплени он вместе с жидкостью выводитс по патрубку 2 вверх в затрубное пространство. Манжета 10 предотвращает возможное осаждение абразива и шлама неносредственно па пакер 9.A ball 6 of the upper valve is mounted and a ball 7 of the lower valve is installed in the saddle 8. Then a gas is supplied through the string of pipes 12, which, coming out of the nozzles 4, dries the liquid out from under the packer 9 to the lower level and removes the pipe 2. It is possible to control the occurrence of gas on the flow in the annulus of the well. After that, the injection fluid with abrasive is pumped into tubing 12. Destroying the wall of the GZ casing, the liquid with abrasive flows down to the lower end of the 2 n sleeve of the cuff 11, which prevents the abrasive from being deposited below the cuff and as it accumulates along with fluid is discharged through pipe 2 upward into the annulus. The cuff 10 prevents the possible deposition of abrasive and cuttings directly on the packer 9.
После окончани процесса перфорации производ т подачу жидкости без абразива дл полного удалени твердой фазы из колонны труб 12 и затрубного пространства. По окончании процесса устройство извлекают из скважины .After completion of the perforation process, a liquid without an abrasive is supplied to completely remove the solid phase from the string of pipes 12 and the annulus. At the end of the process, the device is removed from the well.
В случае необходимости нерфорироваиио пового интервала производ т без спуско-подъемиой операции, при этом клапан 7 удал ют из скважины обратной промывкой, устройство устанавливают в задапиом интервале и цикл операций повтор ют.If necessary, the non-perforated pressure interval is performed without a trip operation, the valve 7 is removed from the well by backwashing, the device is set at a predetermined interval, and the cycle of operations is repeated.
