Based on the theoretical background, this paper firstly analyzes the acoustic mechanism for the oil reservoir and then makes a acoustic response analysis on the sound radiator model for frequency and time-domain investigation by using professional acoustic simulation software LMS Virtual.lab Acoustics, finally calculates the acoustic transmission loss in the downhole oil reservoir.
Generally speaking, if the study is hypothesis driven, one should select the acoustic variables of interest prior to their extraction, based on the theoretical background.
