Abstract

En muffe for et akustisk loggeverktøy har en oppbygning med en vindusseksjon med færre staver enn på en vanlig muffe, samt adskilt fra et slisset område med tynne slisser i omkretsretningen og som er spenningsavlastet ved sine ytreender ("dombjelle"-formet). Mottakerholdere av stål er anordnet for hydrofon-trykkfølere, og dette sammen med aksialt orienterte hydrofoner gjør dette verktøy mindre følsomt for forstyrrende vibrasjoner.
