摘要： A dipole acoustic well logging instrument including an acoustic transmitter. Receiver sections are disposed at axially spaced apart locations from the acoustic transmitter. Each receiver section includes an outer shoulder at each end adapted to be placed in acoustically isolated contact with an internal shoulder of a connector coupling when the instrument is in tension. The outer shoulders have an acoustically isolating material disposed on their surfaces. The receiver sections include an inner shoulder at each end adapted to be placed in direct contact with an external shoulder of the connector coupling when the instrument is in compression. The instrument includes one connector couplings disposed at each end of each receiver section to couple the receiver sections to each other and to the remainder of the instrument. At least one receiver element is disposed in a passage formed into each of the receiver sections. In one embodiment of the invention, the receiver element can be a bimorph-type dipole acoustic sensor. In another embodiment, the receiver element can be formed from a plurality of radially spaced apart piezoelectric elements.

摘要： An apparatus and method for protecting temperature sensitive components from the extreme temperatures a hydrocarbon producing wellbore. The apparatus comprises an inner housing encompassed by an exterior housing, where a plenum is formed between the two housings. A vacuum is formed within the plenum. The temperature sensitive components are stored within the inner housing. An aerogel composition is placed on the outer surface of the inner housing thereby providing added insulation for protecting the temperature sensitive component. Optionally the aerogel composition can be added to the inner surface of the outer housing. Yet further optionally, a reflective foil may be disposed over the aerogel composition of the inner housing.
