The invention relates to an ultrasonic imaging well logging experiment device with a control system, comprising: a two-dimensional sliding scanning platform, a control system, a computer, the two-dimensional sliding scanning platform is electrically connected to the control system, and the control system The system is electrically connected to the computer. The control system includes a cover plate, a hinge, an operation panel, a cover plate buckle and an aluminum alloy box. The cover plate is detachably installed on the aluminum alloy box through the hinge. On the alloy box, an accommodating space is formed between the operation panel and the aluminum alloy box, and a switching power supply, a circuit board, an X-axis stepping motor driver and a Y-axis stepping motor driver are arranged in the accommodating space. The present invention adopts a two-dimensional plane scanning method, and compared with the actual ultrasonic reflected wave imaging logging, its imaging result is more intuitive, therefore, it is very suitable for application in geophysical logging and related professional experimental teaching, making up for such Lack of teaching aids.
Description
technical field [0001] The invention relates to the field of experimental teaching tools, in particular to an ultrasonic imaging logging experiment device with a control system. Background technique [0002] The basic principle of ultrasonic reflected wave imaging logging is: to measure and record the reflected waves of the ultrasonic pulse emitted from the pulsed sound source on the well axis on the well wall at various acoustic interfaces in the downhole, and determine the well surface according to the arrival time of these reflected waves. The position of the acoustic interface on the wall, and the acoustic impedance characteristics of the well wall are determined according to the magnitude of the reflected wave amplitude. According to the arrival time and amplitude of the reflected wave of the ultrasonic pulse on the well wall, the two-dimensional image of the well wall surface is obtained, which is ultrasonic reflected wave imaging. The above principles are not unfamil...
