Abstract

Ловильный инструмент для извлечения на тросе оборудования (1) из ствола скважины содержит установочный конус (10), внутреннюю пружину (11), создающую нагрузку на установочный конус, блокировочный конус (12), расположенный снаружи установочного конуса и нагружаемый внешней пружиной (13), и по меньшей мере один фиксатор (14), поворачиваемый в положение захвата оборудования (1) перемещением установочного конуса и блокировочного конуса посредством соответствующих пружин.The fishing tool for extracting equipment (1) from the wellbore on a cable contains a mounting cone (10), an internal spring (11) that creates a load on the mounting cone, a blocking cone (12) located outside the mounting cone and loaded by an external spring (13), and at least one latch (14) pivotable to the equipment gripping position (1) by movement of the mounting cone and locking cone by means of respective springs.
