Abstract

En fremgangsmåte for overføring av trykkimpulser fra en nedhulls lokalitet gjennom et strømmende fluid i et borehull omfatter bruk av en lineær aktuator for styrbart å bevege et frem- og tilbakegående element aksielt frem og tilbake mellom en første posisjon og en andre posisjon for i det minste delvis å begrense strømningen av det strømmende fluid for å generere trykkpulsene. En frem- og tilbakegående impulsgiver for å generere trykkimpulser i et fluid som strømmer i et borehull omfatter en fluidpassasje som tillater strømningen av fluidet gjennom impulsgiveren, og et frem- og tilbakegående element. Den lineære aktuator er koplet til det frem- og tilbakegående element slik at den lineære aktuator beveger det frem- og tilbakegående element i en første aksiell innretning og deretter i en motsatt retning. For i det minste en delvis å begrense strømningen av fluidet gjennom impulsgiveren for å generere trykkimpulser i det strømmende fluid.
