Abstract

The invention discloses a high-precision drilling imaging device for array type acoustic wave scanning. The scanning head is located at the bottom of the protective casing, the guide cover is arranged at the bottom of the scanning head, and the protective casing is divided into a circuit module cavity and a scanning power by a positioning platen. The lower part of the scanning head is evenly arranged with N acoustic wave probes in the circumferential direction. The present invention also discloses a high-precision drilling imaging method for array acoustic wave scanning. The present invention utilizes multiple acoustic wave probes to realize the array acoustic wave probe Reasonable arrangement of borehole scanning, using the scanning power chamber to realize the omni-directional acoustic scanning detection of boreholes, forming a high-precision borehole imaging system of array acoustic scanning, and solving the problem of acoustic borehole imaging caused by the misalignment of the instrument probe The problem of distorted results and low-precision detection has achieved rich detection data and strong detection adaptability. It has made breakthroughs and substantial progress in the detection accuracy of borehole imaging, and has significant scientific significance and economic and practical value.
