Abstract
Abstract Deep well exploration of oil and gas resources requires acoustic transducers that can withstand temperatures above 200 degrees. It is particularly important to overcome the key technology of high-temperature dipole transmitters. The bonding strength of the dipole transmitters with a tri-laminar structure is studied numerically and experimentally. Transducers were prepared using structural adhesives. The aging and fatigue test is conducted at a high temperature of 200 degrees. The aging lasted for 15 hours and the strong electric field fatigue cycle number reached up to 36000. The conductivity curve remains almost unchanged after the high-temperature test. The work provides an application basis for deep acoustic logging technology.
