The invention discloses a continuous oil pipe operation pit bottom wireless data transmission system, relating to the petroleum and gas industrial continuous oil pipe operation pit bottom wireless data transmission equipment technical field. The system comprises an underground construction monitoring instrument acquiring underground data, a sound wave information coding device in charge of codingthe underground data and converting the underground data into a sound wave signal, a sound wave transmitting device transmitting the sound wave signal, a sound wave receiving device receiving the sound wave signal, an automatic program control amplifier in charge of amplifying the sound wave signal as well as a sound wave information decoding device in charge of adding code into the sound wave information. By adopting the system, the technical problem that the sound wave transmitting device in the existing continuous oil pipe operation pit bottom wireless data transmission system can not utilize a continuous oil pipe to propagate sound wave is solved, namely the fact that a sound wave vibration signal can be directly generated in solid material is realized.
