This paper gives a brief introduction to the fundamental theory and working process of uncabled depth measuring device. When using this system the depth time function is recorded above ground, coupling time function is done under well and the depth coupling function is got from functional exchange. Then the coupling depth is corrected based on magnetic and tubing depth data, and the accurate position of the borehole device can be obtained. This method can eliminate the depth record error resulted from human factor and mechanical factor. The error of the system is less than 0 3‰m during field test and verification in standard wells. So, it can fully meet the demands of field tests. The testing technology is further improved due to the automatic measurement of well testing depth. It lays a good foundation for digitization.
