CONTROL OF ACOUSTIC TRANSMITTERS FOR DOWNHOLE MEASUREMENT OR LOGGING |
摘要 |
The acoustic energy induced by a transmitter module of an acoustic logging tool is dependent on several factors. In some implementations, the induced acoustic energy is dependent on the electromagnetic energy input into the transmitter module, the response behavior of the transmitter module, and the operating conditions of the transmitter module. Variation in one or more of these factors can result in a corresponding variation in the induced acoustic. Thus, a desired acoustic signal can be produced by applying an appropriately selected input signal to the transmitter module, while accounting for other factors that influence the output of the transmitter module. |
