(54) УСТРОЙСТВО ДЛЯ УСТАНОВКИ Гр 1 РИР ЖАННСаХ) ПЕРБКРЫВАТЕЛЯ В СКВАЖИНЕ(54) DEVICE FOR INSTALLATION Gr 1 RIR ZHANNSAH) PERSON IN THE WELL

новременного раскрыти  перекрывател . К конусу 4 выправл ющего узла, установленного на верхнем конце перекрывател  с одного конца навинчен ствол 7, на котором yctaHoe eH стакан 8, в полости которого помешена пружина 9, а на наружной поверхности установлена обойма 10 с выполненными радиальными окнами И, куда вход т хвостовики конусных плашек 2 и 3; а с другого конца - навинчен патрубок 12 с радиальными каналами 13 и оканчивающийс  шлипсовой головкой 4 под ловитель 15, соединенный с патрубком 16, снабженным клапаном 17, а также с установленными на нем башмаком 18 и выправл ющим узлом.modern opening overlap. A barrel 7 is screwed to the cone 4 of the straightening unit mounted on the upper end of the clapper, on which the yctaHoe eH cup 8, in the cavity of which the spring 9 is placed, and on the outer surface the holder 10 with radial windows installed and where the shanks enter conical dies 2 and 3; and at the other end, a pipe 12 with radial channels 13 is screwed on and terminated in a slip-head 4 under a safety device 15 connected to a pipe 16 equipped with a valve 17, as well as a shoe 18 and a straightening unit mounted on it.

Гидравлическа  камера 6 сообщена с центральными каналами ствола 7 и патрубка 16 через радиальные каналы 13 и 19. Устройство в верхней части снабжено защитным колпаком 20.The hydraulic chamber 6 communicates with the central channels of the barrel 7 and the nozzle 16 through the radial channels 13 and 19. The device in the upper part is equipped with a protective cap 20.

Устройство работает следующим образом. Его опускают в скважину на колонне бурильных труб. По достижении интервала установки в трубы закачивают промывочную жидкость, клапан 17 при этом закрываетс , давление в полости бурильных труб н в гидравлической камере повышаетс . Стенки гофрированного перекрывател  1, воспринима  давление, выправл ютс , плотно прилега  к стенке скважи ны. Одновременно происходит выправление концевых участков перекрывател . Так как принцип выправлени  обоих концов аналогичен, .опишем работу верхнего выправл ющего узла.The device works as follows. It is lowered into the well on the string of drill pipes. When the installation interval is reached, the flushing fluid is pumped into the pipes, the valve 17 closes at this time, and the pressure in the cavity of the drill pipes and the hydraulic chamber rises. The walls of the corrugated slab 1, perceiving the pressure, straightened tightly against the wall of the well. Simultaneously, the alignment of the end portions of the overlapping occurs. Since the principle of straightening both ends is similar, let us write the operation of the upper straightening unit.

Под воздействием давлени  в гидравлической камере 6 конус 4 перемещаетс  вверх, распира  плащки 2 и 3, что приводит квыправлению контактируемых с ними концевых участков перекрывател . После достижени  расчетного давлени  прекращают подачу промывочной жидкости и колонну бурильных труб подают вниз. При этом конус 4, перемеща сь вниз, выводит плашки 2 из зацеплени  с зубчатыми насечками перекрывате   и последние за счет пружины 9 и обоймы 10 перемест тс  в верхнее положение, предотвраща  заклинивание плащки 2 при подъеме устройства на поверхность. Далее инструмент опускают до захвата ловител  15 шлипсовой головкой 14. При нат жке бурильных труб нижний конус 4, двига сь вверх, освобождает нижние плашки 2 из зацеплени , с перекрывателем, после чего они также принимают транспортное положение и устройство поднимают на поверхность.Under the influence of pressure in the hydraulic chamber 6, the cone 4 is moved upwards, the sheathing of the cap 2 and 3, which leads to redirecting the end sections of the overlapters in contact with them. After reaching the design pressure, the supply of flushing fluid is stopped and the string of drill pipes is fed down. In this case, the cone 4, moving downwards, removes the dies 2 from engagement with the notched teeth and the latter, due to the spring 9 and the casing 10, moves to the upper position, preventing the closure 2 from jamming to the surface. Next, the tool is lowered to the catch by the catcher 15 with the slip head 14. When the drill pipes are tightened, the lower cone 4, moving up, releases the lower rams 2 from engagement with the interrupter, after which they also take the transport position and raise the device to the surface.

Предлагаемое устройство позволит исключить холостые рейсы по спуску и подъему устройства , быстро и надёжно устанавливать перекрыватель , что в конечном итоге ускорит изол ционные работы в скважинах и приведет к экономии материальных средств.The proposed device will allow eliminating idle runs on the descent and ascent of the device, quickly and reliably install a shutter, which ultimately speeds up the insulation work in the wells and leads to savings in material resources.
