Underground storage wells borehole detection system integrated automation and detection method

The present invention relates to a shaft wall underground gas detection system integrated automation and test method for gas well borehole wall thickness of corrosion detection and crack detection. The system includes an uphole host computer, the position measuring device, cable lifting devices, the DC power supply and the underground movement detector, portable detector through the cable communications equipment armored with Inoue and get power, space-saving cable occupied, facilitate field operations. Mobile detector equipped with a wall thickness of corrosion detection and crack detection probe Probes group, can simultaneously detect corrosion and cracks on the wall thickness, the detection gas wells more comprehensive. At the same time, the system integration of downhole equipment incentives, reception amplification, signal processing and transmission functions, so that the ultrasonic signal without going through the long-distance transmission to the ground and then processed, greatly improving the signal to noise ratio and fidelity, so test results more accurate.
