The employment of the piezoelectric ceramic block capable of generating resonance as a medium for conversion between sound waves and electric signals, as well as the arrangement of the metal sheets with a certain level of elasticity on the two sides of the piezoelectric ceramic block, enables the utility model to effectively realize the conversion between the sound waves and the electric signals.
Description
Technical field
The utility model relates to a kind of cementing imaging logging instrument transducer.
Background technology
At present, in cementing imaging logging instrument well logging process, when instrument signal is launched, the high-voltage pulse signal of telecommunication of peripheral circuit need be changed the acoustic signals of fixed frequency, measure as the sound wave emissions signal of cementing imaging logging instrument.In addition, when the instrument received signal, acoustic signals need be converted to the signal of telecommunication with this acoustic signals frequency dependence, measuring-signal as the cementing imaging logging instrument, and after through instrument it being handled,, offer logging system and carry out imaging as the measurement achievement of instrument.This just need add the energy conversion device of the sound wave and the signal of telecommunication in the cementing imaging logging instrument.At present, domestic still do not have a this energy conversion device.And the external disclosure that does not also have correlation technique makes the logging effect of domestic cementing imaging logging instrument be subjected to serious puzzlement.
The utility model content
The technical problems to be solved in the utility model provides a kind of device that can carry out sound wave and electrical signal energy conversion.
In order to address the above problem, the utility model provides a kind of cementing imaging logging instrument transducer, comprise: the piezoelectric ceramics block of the produced resonance of being made up of at least two video discs and be arranged on the sheet metal of described piezoelectric ceramics block both sides, described sheet metal is provided with first interface and second interface that is used to carry the signal of telecommunication.
Further, described piezoelectric ceramics block is made up of four video discs.
