Description
до забо имеютс рабочие выступы 3, производ щие доразрушение породы. Виутри корпуса над насадками расположен вращающийс диск 4 с приводом. В качестве привода диска может быть использована турбина, установленна на пути потока жидкости. В этом случае на валу 5 устанавливаетс ротор 6, а в корпусе неподвижно закреплен направл ющий аппарат 7.before the bottom there are working protrusions 3, which produce additional destruction of the rock. In the case of the housing, a rotating disk 4 with a drive is located above the nozzles. As a disk drive can be used turbine installed in the path of fluid flow. In this case, the rotor 6 is mounted on the shaft 5, and the guide device 7 is fixedly mounted in the housing.
Диск имеет дугообразные прорези 8, длина дуги которых равна длине дуги между ос ми насадок. Такое выполнение прорезей в диске и соответственное расположение насадок обеспечивает посто нство нроходного сечени прн вращении диска над насадками. Дл центровки на нижней его стороне вынолнен выступ 9, размещенный в пазу на нижней торновой поверхности корпуса. С помощью уплотнений 10 и 11 уменьшаетс возможность перетока жидкости.The disk has arcuate slots 8, the arc length of which is equal to the arc length between the nozzle axes. Such an implementation of the slots in the disk and the corresponding location of the nozzles ensures the constant cross section of the rotation of the disk above the nozzles. To center on the lower side, a protrusion 9 is placed, which is placed in a groove on the lower torn surface of the hull. Seals 10 and 11 reduce the possibility of fluid flow.
Устройство работает следующим образом.The device works as follows.
Жидкость через колоину бурильных труб подаетс к забойному устройству и приводит во вращение диск 4, который нопеременно открывает и закрывает соответствующие насадки . Однако, ввиду того, что длина дуги прорезей равна длине дуги между смежиыми насадками , обща суммарна площадь открытого сечени остаетс носто нной. Таким образом , жидкость поступает то в одни, то в другие насадки, осуществл струйное импульсное воздействие на забой при ирактически посто нном нерепаде давлени на устройстве .Fluid through the drill pipe coloin is supplied to the downhole tool and spins the disk 4, which alternately opens and closes the corresponding nozzles. However, due to the fact that the length of the arc of the slots is equal to the length of the arc between the adjacent nozzles, the total total area of the open section remains standing. Thus, the liquid enters one or another of the nozzles, having produced a jet impulse effect on the bottomhole at an almost constant pressure non-pressure on the device.
