Description
двигател и жестко соединенное с втулкой 9. Переводники 3 и 5 соединены между собой посредством резьбового соединени , нанример нри помощи левой резьбы.motor and rigidly connected to the sleeve 9. Subs 3 and 5 are interconnected by means of a threaded connection, using a left-handed thread.
Устройство работает следующим образом.The device works as follows.
В случае прихвата забойного двигател в скважине в бурильные трубы бросают шар б, который потоком промывочной жидкости перемещаетс до кольца И, перекрыва проходное отверстие. Под действием гидравлического усили , действующего на верхний торец кольца 11, полый цилиндр 10 разрываетс и перемещаетс с нижней полумуфтой 8, втулкой 9 и кольцом 11 вниз до посадки последнего на вал 2 забойного двигател 1. Направление потока промывочной жидкости показано стрелками на фиг. 2. Затем, враща бурильные трубы вправо, переводник 3 отсоедин ют от переводника 5. В случае отсутстви возможности циркул ции промывочной жидкости внутри бурильной колонны разрыв полого цилиндра 10 осуществл етс посредством бросового щтока.In the event that a downhole motor is stuck in the borehole, a ball b is thrown into the drill pipes. Under the action of the hydraulic force acting on the upper end of the ring 11, the hollow cylinder 10 is broken and moved with the lower coupling half 8, sleeve 9 and ring 11 down until the latter is seated on the shaft 2 of the downhole motor 1. The direction of flow of the flushing fluid is shown by arrows in FIG. 2. Then, rotating the drill pipes to the right, the sub 3 is disconnected from the sub 5. In the event that the flushing fluid does not circulate inside the drill string, the hollow cylinder 10 is ruptured by means of a waste rod.
