摘要： An acoustic tool for evaluating a geologic formation includes a housing member disposed between transmitter and receiver sections of the acoustic tool. The housing member defines a change in direction in an acoustic path extending therethrough such that acoustic signals traveling through the housing member are delayed and disrupted. The delay and disruption may isolate the acoustic signals traveling through the housing member from acoustic signals traveling through the geologic formation. Thus, the acoustic tool may facilitate identification and evaluation of acoustic signals traveling through the geologic formation.

摘要： There is provided a transducer assembly (320, 1000, 2000) for monitoring within a borehole (10). The transducer assembly (326, 1000, 2000) is operable to at least one of: (a) generate acoustic radiation when excited with one or more signals (390); and (b) generate one or more signals (360) when acoustic radiation (350) is received thereat; wherein the transducer assembly (320, 1000, 2000) includes one or more piezo-electric elements for converting between acoustic radiation and corresponding signals. The assembly (320, 1000, 2000) includes an interfacing member (452) for acoustically interfacing between the one or more piezo-electric elements (460) and an environment of the borehole (10) for protecting the one or more piezo-electric elements (460) from the environment. The assembly (320, 1000, 2000) is adapted to at least one of generate acoustic radiation and sense acoustic radiation in a sideways or down-borehole (10) direction.

摘要： An acoustic well logging tool (11) is shown having a transmitter section (17) and a receiver section (19) spaced apart by a semi-rigid housing (21). The semi-rigid housing (21) includes a number of rigid tubular members (27, 29) which are joined by interlocking lobes (33, 35) which permits relative movement between the tubular members but which prevents the separation thereof. Gaps (49) between the interlocking lobes (33, 35) 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 (17) along the body of the tool is delayed and attenuated.

摘要： The logging tool (90) of this invention includes a transmitter (105) conveyed on a drilling collar for exciting a quadrupole signal (106) in a borehole being drilled by a drill bit and a receiver for receiving the signal. The transmitter is operated at a frequency below the cut-off frequency of the quadrupole collar mode. The received signal consists primarily of the formation quadrupole mode which, at low frequencies, has a velocity that approaches the formation shear velocity. The transmitter, in one embodiment, consists of eight equal sectors of a piezoelectric cylinder mounted on the rim of the drilling collar. The value of the cut- off frequency is primarily dependent on the thickness of the drilling collar. Alternatively, the transmitter may be operated to produce both the collar mode and the formation mode and a processor may be used to filter out the collar mode.

摘要： An acoustic logging apparatus includes a tool body and a housing. A transducer operating in the bending mode is mounted in the housing. The transducer operates such that it is excited by or emits acoustic energy in only one of the two directions substantially perpendicular to the face of the transducer. The housing is mounted substantially removed from the axis of the body. An acoustic receiver includes an outer sleeve having a flange and a hat slidably mounted within the outer sleeve. The sliding of the hat compensates for variations in pressure and temperature. An acoustic transmitter includes a main housing and a hat slidably supported within the main housing. The sliding of the hat compensates for variations in pressure and temperature. Combinations of air gaps and o-rings in the transducer acoustically isolate a piezoelectric crystal from its housing and the housing from its enclosure, The acoustic receiver and acoustic transmitter are configured to be replaced in the filed.
