Abstract: High-temperature dipole transducer is one of the main key technologies needed to be tackled in
the research and development of the 200 C multipole array sonic logging tools. Focusing on this shortcoming,
◦
this paper carries out technical researches from the following two aspects: material selections and process
improvement, and finally a 200 C dipole transducer sample is successfully developed. The results of sample
◦
temperature test show that it can work continuously at 200 C more than 12 hours without damage. The
◦
transmitting voltage response is up to 124 dB, which is nearly the same as that of current dipole transducer
at room temperature. The dimension of the sample is totally the same as that currently used in logging
instrument, so it is very convenient to upgrade current instrument. Now the sample carried in the instrument
has passed the test of GUGU8 experimental well, and also has obtained high quality data in the nearly 9000 m
deep well of the ShunBei oilfield in Xinjiang province, which achieves the beginning design purpose. This paper
provides a new research thinking for developing higher temperature transducer.
