Beschreibung
Zusammenfassung:	The utility model discloses a near-bit measurement while drilling sound wave short distance transmission device which is designed for realizing real-time collection and uploading of near-bit measurement data and obtaining reliable data for stratum evaluation. The upside of a drill bit is connected with a near-bit measuring apparatus, a screw drill and a wireless while drilling instrument successively. Measurement and real-time transmission of near-bit underground work data are performed by a sensor set, underground computer modules, power packs and sound wave transmitting and receiving transducer sets. The near-bit measurement-while-drilling sound wave short distance transmission device is capable of realizing communication between the near-bit measuring apparatus and the while-drilling instrument, guaranteeing the real-time collection and uploading of the near-bit measurement data, and providing reliable underground drilling parameter data for real-time stratum evaluation. The near-bit measurement-while-dril
