Claims

1. A drilling measurement instrument with a vibration damping structure, comprising a first connecting pipe (1), characterized in that: One end of the first connecting pipe (1) is connected to a second connecting pipe (3) via a buffer shell (2). The two ends of the buffer shell (2) are screwed to the first connecting pipe (1) and the second connecting pipe (3) respectively. Fixing members are installed on the outside of the buffer shell (2) near both ends. The fixing members are used to fix the first connecting pipe (1) and the second connecting pipe (3). Two sets of shock absorbers for energy absorption and buffering are installed on the inside of the buffer shell (2). The shock absorber includes a damping ring (4) fixedly installed on the inside of the buffer shell (2). A plurality of fixed cylinders (5) arranged in a circle are fixedly connected to one side of the buffer shell (2). A support rod (6) is slidably connected to the inside of the fixed cylinder (5). A shock absorber (7) is fixedly connected to the inside of the fixed cylinder (5). A first spring (8) is fitted on the outside of the shock absorber (7). The other end of the support rod (6) is fixedly connected to the buffer shell (2). The shock absorber also includes a buffer... A fixed rod (9) is fixedly connected to one side of the shell (2) near the center, and a fixed frame (10) is fixedly connected to the other side of the buffer shell (2) near the center. An energy-absorbing ring (11) is fitted on the outside of the fixed rod (9). The fixed rod (9) and the fixed frame (10) are slidably connected. A second spring (12) is fixedly installed between the fixed frame (10) and the fixed rod (9). The fixing component includes two movable cavities (13) respectively opened at both ends of the buffer shell (2). A sliding plate (14) is slidably connected to the inside of the movable cavity (13). A locking rod (15) is fixedly connected to the bottom of the sliding plate (14). A screw (16) is screwed to the inside of the movable cavity (13). The screw (16) is rotatably connected to the sliding plate (14) through the fixing part (161) and does not detach. Two locking grooves (17) are opened at one end of the first connecting pipe (1) and one end of the second connecting pipe (3).

2. The MWD tool with a shock-absorbing structure according to claim 1, characterized in that: Two guide rods (18) are fixedly installed inside the active cavity (13). The guide rods (18) pass through the sliding plate (14) and are slidably connected to it.

3. The MWD tool with shock-absorbing structure according to claim 1, characterized in that: The damping ring (4) has multiple arc-shaped parts (401) evenly arranged on both sides.

4. The MWD tool with shock absorbing structure according to claim 1, characterized in that: A third spring (19) is fitted on the outside of the support rod (6), and the two ends of the third spring (19) are fixedly connected to the fixed cylinder (5) and the support rod (6) respectively.
