Embodiment Construction
[0013] The fully coupled dry-hole acoustic wave probe of the present invention will be further described in detail below with reference to the accompanying drawings.
[0014] see Attachment
[0015] The fully coupled dry-hole acoustic probe consists of a pressurized water bladder 3, an acoustic probe 2, a water inlet pipe and a connecting device 5. The pressurized water bladder 3 is made of styrene-butadiene rubber, and the pressurized water bladder 3 is cylindrical. One end of the bladder 3 is open and the other end is closed. On the top of the closed end of the pressurized water bladder 3, there is a vent hole 1, the diameter of the vent hole 1 is ≦1mm, and the end of the acoustic wave probe 2 is provided with a connecting device 5. The connecting device 5 is provided with a water inlet channel 4 and a cable channel 6 , the pressurized water bag 3 is set outside the acoustic wave probe 2 , and the opening end of the pressurized water bag 3 is located on the connecting device...
