Abstract

Un método de medición durante la perforación para cambiar momentáneamente la velocidad de un generador de señal acústica desde su régimen normalmente constante para efectuar un cambio de fase apropiado en dicha señal acústica. Incluyendo el paso de cambiar la velocidad del generador apartándola del régimen normal, caracterizado por: generar un par de señales digitales en respuesta a dicho paso de cambio de velocidad del generador, siendo indicativa la diferencia entre dichas señales digitales del cambio en la fase de la señal acústica causado por el cambio en el motor del generador y apartandola del régimen normal, caracterizado por: generar un par de señales digitales en respuesta a dicho paso de cambio de velocidad del generador, siendo indicativa la diferencia entre dichas señales digitales del cambio en la fase de la señal acústica causado por el cambio en el motor del generador y detener dicho cambio de velocidad del generador que lo aparta de su régimen normal cuando la diferencia entre dichas señales digitales alcanza un valor predeterminado indicativo de una variación de fase predeterminada.
