Embodiment Construction
[0011] The content of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0012] Such as figure 1 As shown: the fracturing device is composed of an ignition device 2 , an output joint 3 of the ignition device, a fracturing bomb 4 , an intermediate joint 5 and a tail plug 6 connected in sequence. In order to facilitate cleaning the bottom of the well after fracturing, a T-shaped fishing head 1 is connected to the upper end of the ignition device 2, and the T-shaped fishing head 1 can be grasped by movable claws, thereby taking out the wreckage.
[0013] Such as figure 2 Shown: ignition device 2 is cylindrical, is mainly made up of shell 7, T-shaped salvage head 1, the pilot valve 8 that opens with spring control, the striker piston 91 that is contained in striker barrel 9 and ignition core seat 10 etc. composition. Among them, the pilot valve 8 and the striker cylinder 9 are respectively connected to the up...
