Abstract
An acoustic well logging tool is shown having a transmitter section and a receiver section spaced apart by a semi-rigid housing. The semi-rigid housing includes a number of rigid tubular members which are joined by interlocking lobes which permit relative movement between the tubular members but which prevent the separation thereof. Gaps between the interlocking lobes are filled with a connecting material which differs significantly in acoustic impedance from the material of the remainder of the housing, whereby acoustic energy passing from the transmitter section along the body of the tool is delayed and attenuated.
