Description

technical field [0001] The invention relates to the technical field of oil exploitation, in particular to a modular acoustic wave receiving transducer device. Background technique [0002] At present, in acoustic instruments, there are generally only transmitting and receiving transducers in the sound system. Since the main medium in the sound system is oil, there is no circuit part. The advantage of this structure is that the structure is relatively simple, but the disadvantage is that since the circuit part needs to be separated, there will be a short section of the electronic circuit, which will cause the overall length of the instrument. In addition, the circuit part of the acquisition and processing receiving transducer is far away from the receiving transducer, and signal interference and loss may occur during acquisition and processing, which will eventually affect the quality of the logging curve of the acoustic wave tool. Contents of the invention [0003] The pu...
