Abstract

Un método para medición durante la perforación para cambiar momentáneamente la velocidad de un generador de señal acústica excitado por motor desde un régimen normalmente constante que provee una señal de frecuencia de portadora para efectuar un cambio de fase seleccionado para modular dicha señal de portadora, que comprende los pasos de: (a) cambiar la velocidad del generador apartándola del régimen normal para acumular una porción del cambio de fase seleccionado, y (b) hacer retornar la velocidad del generador al régimen normal para con ello acumular el resto de dicho cambio de fase seleccionado, caracterizado por: generar una señal de control cuando el cambio de fase acumulado en uno de los pasos (a) y (b) alcanza un valor prescripto; y ajustar dicho valor prescripto en respuesta al cambio de fase acumulado durante por lo menos un paso precedente del otro de los pasos (a) y (b).
