Optical Televiewer HD Photo Downhole Imaging Analyzer Multi Function Full 3D Borehole Wall Imaging Tool Optical Borehole Imaging Tool
1. Analysis of pore wall structure. Can clearly and intuitively see the various anomalies and defects in the pile, quantitative analysis of joint quality and fracture, fracture, length, width and inclination of the crack; etc.; can provide sufficient, true and complete test data;
2. Applicable to engineering geology, hydrogeology, geotechnical engineering, mining and petroleum geology departments. It can directly observe various characteristics and subtle phenomena of geological bodies in the borehole, such as stratum lithology, rock structure, faults, fissures, interlayers, karst and so on. Groundwater flow rate, flow direction, groundwater recharge, etc. can also be observed;
3. Concrete pouring quality, underground pipeline damage detection, underground instrument embedding monitoring, etc.;
Water well maintenance, detecting cracks, misalignment, falling objects in the well wall, plugging of the filter pipe and the position of sand flow.
Principle:
The intelligent borehole optical imager, also known as the well-being TV, is an image of the inner wall of the tube hole that is captured by the latest high-definition, high-definition and high-resolution in-hole camera probe using the latest TV camera technology;
The depth recording device records the depth position of the transducer.
With various signal processing and imaging functions, the various states of the hole wall can be clearly reflected on the monitor on the ground, and the system can planarly unfold the image and automatically realize seamless stitching.

Downhole TV imaging system is a new logging technology, which can directly monitor downhole tubing or casing technology. Digital image processing, image segmentation and edge tracking are carried out on downhole TV image by using digital image processing technology. And the imaging principle during the television image is obtained using physical geometry size, to achieve the quantitative interpretation of downhole television, through the practical application shows that the interpretation results are accurate and reliable quantitative methods, is further perfect of downhole television logging technology, infrared thermometer and complementary to the borehole imaging, logging to play an important role. In practical observation, the quality of detector determines the quality of TV imaging.
