Problems solved by technology

There is no need to open stepped holes in the gun body, and the tool end of the EDM directly extends into the perforating gun body and punches holes at the corresponding positions on the inner wall, which solves the problem of poor pressure bearing capacity of the externally blocked inner blind hole perforating gun, and reduces Blocking, welding and other processes to avoid the impact of high temperature welding on the performance of the gun body

Embodiment 1

[0026] Referring to each figure, a processing device for processing blind holes in a perforating gun in pairs, the processing device includes a worktable 1, a moving and rotating mechanism 3, a spring guide wheel mechanism 5, a flow regulating device 6, a connecting frame 7, an electric spark Pulse power supply 15, electric discharge machining mechanism 8, supporting and fixing mechanism 9, power transmission mechanism 11 and working fluid circulation filtering system; the workbench 1 is fixed on the ground, and it plays a load-bearing role for the entire processing device; the moving and turning mechanism 3. Installed and fixed on the workbench 1, the mobile rotary mechanism 3 clamps and fixes the perforating gun frame 4, and can make it rotate; the mobile rotary mechanism 3 includes an indexing plate 31, an indexing plate hand wheel 32, and The blue plate 33, the three-jaw chuck 35 and the three-jaw chuck rocker 34, the index plate 31 are fixed on the workbench 1 by bolts, th...

Embodiment 2

[0028] A processing method for processing blind holes in perforating guns using a pair of processing devices for processing blind holes in perforating guns, the processing method includes the following steps:

[0029] The first step is to clamp the lower end of the perforating gun body 4 on the three-jaw chuck 35, and fix the upper end of the gun body through the supporting and fixing mechanism 9; the starting motor 111 moves the lifting screw 116 longitudinally through the power transmission mechanism 11, and connects The frame 7 and the EDM mechanism 8 extend vertically into the perforating gun body 4, and at the same time, the spring guide wheel mechanism 5 below the connecting frame 7 supports the righting EDM mechanism 8 until the paired tool electrodes 83 and the inner blind to be processed Turn off the motor 111 when the hole position reaches the same horizontal position;

[0030] The second step is to rotate the perforating gun frame 4 by moving the rotary mechanism 3,...

Abstract

The invention belongs to the technical field of mechanical processing equipment, and specifically relates to a processing device and a processing method for processing blind holes in perforating guns in pairs. Connecting frame, EDM pulse power supply, EDM mechanism, supporting and fixing mechanism, power transmission mechanism and working fluid circulation filtering system; the perforating gun body is clamped on the workbench, and the lead screw is driven by the cooperation of the worm gear and the lead screw Carry out longitudinal movement, and extend the electric discharge machining mechanism into the gun body of the perforating gun through the spring guide wheel device on the connecting frame. The paired tool electrodes are aligned with the two inner blind holes to be processed on the inner wall of the gun body by using the moving and turning mechanism. The working fluid flowing into the perforating gun body through the working fluid pump and catheter tube, the tool end is connected to the anode of the EDM pulse power supply, and the perforating gun body is connected to the cathode of the EDM pulse power supply to form an EDM discharge circuit to realize internal blindness. Pair processing of holes.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a processing device and a processing method for processing blind holes inside a perforating gun in pairs. Background technique [0002] Perforating guns are widely used in the production and development of oil and gas wells for completion or cementing. In recent years, external blind hole perforating guns have been used more often in the domestic market. This method has certain limitations in increasing the blast height. As the requirements for drilling technology become higher and higher, more stringent requirements are put forward for perforation technology. At present, internal blind hole perforating guns are used in China to gradually replace external blind hole perforating guns. Compared with the external blind hole perforating gun, the inner blind hole perforating gun has the advantages of increasing blast height, facilitating jet exten...
