Embodiment 1
[0045] refer to figure 1 , is the downhole ultrasonic detector disclosed by the present invention, comprising a mounting frame 1 installed above the wellhead, on the mounting frame 1 is hoisted a lifting device 2 towards the inside of the well, an ultrasonic probe 3 is arranged on the lifting device 2, and an ultrasonic probe 3 is arranged inside There are several ultrasonic transducers 31 and the driving device 4 that drives several ultrasonic transducers 31 to approach or move away from the hole wall synchronously, and also includes a receiving device arranged on the ground, and the receiving device is connected to the ultrasonic probe 3 through a wireless or wired connection. .
[0046] Mounting frame 1 comprises three support rods 12 hinged on the same support plate 11, triangular in shape when three support rods 12 are stretched out, support plate 11 is placed on wellhead, and three support rods 12 are placed around the wellhead circumference. The lifting device 2 includ...
Embodiment 2
[0066] A boulder detection method, comprising the following steps:
[0067] S1 drilled to get the detection hole, the details are as follows:
[0068] Drilling holes on the ground with a diameter of 168mm and a final hole of 91mm;
[0069] S2 detection, as follows:
[0070] Extend the ultrasonic detector into the detection hole, the ultrasonic detection equipment is provided with an ultrasonic probe 3, and a plurality of ultrasonic transducers 31 are arranged in the ultrasonic probe 3, and several ultrasonic transducers 31 driving the ultrasonic detector are pressed against the detection hole at the same time On the hole wall, ultrasonic detection is carried out. When the detection hole drilled for the first time is a soil layer, the ultrasonic probe 3 is put into the detection hole by the winding rope 22, and the driving motor 41 drives the ultrasonic transducer 31 so that the ultrasonic transducer 31 It is vertically coupled with the hole wall, and the ultrasonic probe 3 i...
