Problems solved by technology

[0002] In petroleum downhole instruments, circuit skeleton components in drilling and directional well instruments are required to be sealed, so there are multiple sealing rings on the circuit skeleton. When installing and removing the circuit skeleton, these sealing rings will be stressed at the same time, forming a large The resistance makes it generally difficult to install and disassemble by manpower. The special installation and removal tools currently used, as the circuit skeleton continues to penetrate or pull out the drill collar, because the axial length of the tool cannot be adjusted, it is necessary to constantly replace special tools with different strokes. Tools, this way of frequent tool replacement brings a lot of inconvenience to installation and disassembly, low efficiency, greatly consumes the physical strength and patience of assembly engineers, and is not conducive to carrying out a large number of disassembly and assembly work
