摘要： An example apparatus for downhole cement inspection may include a tool body and an acoustic transmitter coupled to the tool body. An acoustic receiver may be coupled to the tool body at a first distance from the acoustic transmitter. A first array of acoustic receivers may be coupled to and positioned around a circumference of the tool body at a second distance from the acoustic transmitter. The second distance may be greater than the first distance. The acoustic receiver may be one receiver of a second array of acoustic receivers coupled to and positioned around the circumference of the tool body at the first distance. The first distance may be approximately three feet and the second distance may be approximately five feet.
