FIELD: apparatus for displacing, setting, locking, releasing or removing tools, packers or the like in boreholes or wells, particularly releasable borehole perforator connection units and methods of usage thereof. ^ SUBSTANCE: releasing device for perforator separation of tubing string inside well bore comprises sealing mechanism arranged between tubing string and perforator to isolate well bore. Device also has equalizing mechanism to establish communication between flow string and well bore. Method for automatic perforator releasing involves connecting perforator to flow string comprising pressurized fluid; providing perforator detonation to separate thereof from flow string; equalizing pressure inside flow string and in well to remove perforator from flow string. ^ EFFECT: provision of automatic releasing after detonation and increased safety for well structure. ^ 19 cl, 7 dwg |
