Description

Technical Field

[0001] The utility model relates to the technical field of drill bits, and in particular to an intelligent drill bit with a microstructure sensor. Background Art

[0002] Measurement while drilling and intelligent drilling are the development trends of drilling in the future. Among them, the intelligent drill bit can automatically sense the formation pressure and downhole temperature, measure the dynamic parameters of the drill bit, and provide the working conditions at the drill bit to the personnel on the well in real time, so as to adjust the drilling parameters and improve the drilling efficiency. After searching, a Chinese patent with the authorization announcement number CN217681701U discloses an intelligent drill bit with a detachable measuring pup joint. The drill bit is mainly composed of a drill bit body, a measuring pup joint and a measuring device fixed in the measuring pup joint. During the process of rock crushing by the drill bit, the data acquisition module in the measuring device can collect the actual working data of the drill bit such as rotation speed, acceleration, temperature, pressure, etc., and feed it back to the drilling site at the same time. The implementation manner of the present application can directly and accurately reflect various actual working condition data on the drill bit by setting the data acquisition module in the flow channel inside the drill bit body, effectively avoiding data distortion caused by other interferences; by relatively fixing the measuring device to the drill bit body or to the measuring short section, the reliability of the collected data is guaranteed, and at the same time, it is ensured that there is no relative movement between the measuring device and the drill bit or the measuring short section, and the measuring device is easy to disassemble, so that the measurement data can better reflect the actual working conditions.
