[0002] Rotary steerable drilling technology is widely used in oil and gas exploration, especially in high temperature and high pressure environments. In order to ensure the efficient and stable operation of rotary steerable drill bits under these extreme conditions, high temperature resistant shock absorbing tools are indispensable. These tools can reduce vibration during drilling, protect drilling equipment and improve drilling efficiency.

[0003] When using the existing rotary guided high temperature resistant shock absorbing tool, it is necessary to use a tool to install the rotary guided high temperature resistant shock absorbing tool between the drill rod and the drill bit. The rotary guided high temperature resistant shock absorbing tool can rotate synchronously with the drill bit and buffer the vibration and impact force generated by the drill bit. The installed rotary guided high temperature resistant shock absorbing tool is exposed to the inside of the borehole, which makes it easy for a large amount of gravel and mud generated by the borehole to enter the protective cover of the rotary guided high temperature resistant shock absorbing tool, which not only easily causes friction damage to the outer surface of the rotary guided high temperature resistant shock absorbing tool, but also affects the buffering and shock absorbing effect of the rotary guided high temperature resistant shock absorbing tool, thereby reducing the service life of the rotary guided high temperature resistant shock absorbing tool.
