Information while drilling sound wave transmission relay transmitting device

Abstract

The invention relates to the technical field of devices for transmitting information while drilling of petroleum and natural gas drilling engineering, in particular to an information while drilling sound wave transmission relay transmitting device. The information while drilling sound wave transmission relay transmitting device comprises a transducer connector, a sound wave receiving connector, a sound wave receiving sensor, an instrument cabin body, an instrument cabin sealing assembly, an underground power module, an underground circuit module and a sound wave transducer assembly. The sound wave receiving connector is fixedly installed at the lower portion of the transducer connector. The information while drilling sound wave transmission relay transmitting device is reasonable and compact in structure and convenient to use, receives a sound wave signal transmitted by a lower-portion drill column through the sound wave receiving sensor, converts the sound wave signal into an electrical signal and transmits the electrical signal to the underground circuit module, and the electrical signal is disposed by the underground circuit module and then transmitted to the sound wave transducer assembly. The information while drilling sound wave transmission relay transmitting device can greatly increase an effective transmission distance of the sound wave signal, accordingly reduces drilling risk, improves the well drilling benefit and has the advantages of being good in overall strength, flexible in use, good in adaptability and accurate and quick in transmission.

Description

technical field [0001] The invention relates to the technical field of an information transmission device while drilling for oil and natural gas drilling engineering, and relates to a relay and forwarding device for acoustic wave transmission of information while drilling. Background technique [0002] At present, in order to adapt to the future development direction of drilling technology informatization, automation, and intelligence, and to meet the needs of the current drilling speed increase and the popularization and application of drilling technologies such as gas drilling, underbalanced drilling, managed pressure drilling, and risk-free drilling, it is necessary to break through the current downhole drilling technology. Information identification lag, low transmission rate and other technical bottlenecks, timely understanding of engineering and geological parameters in the drilling process is an important guarantee to reduce the occurrence of complex situations in the ...
