【Abstract】 This article introduces mainly the theoretical basis and the interpretation of application on acoustic frequency spectrum. It applies for multiple frequencies to detect various radial depths as a new acoustic logging method. Firstly we introduce the concept of Acoustic Frequency Spectrum, and secondly we design three main frequency (10 K, 20 K, 40 K) acoustic transducers in acoustic sonde. We design basic interpretation scheme of acoustic frequency spectrum logging, and discuss various application, such as porosity, permeability, identify of hydrocarbon, crack, and mechanical parameter, application in cased-hole.更多还原
