Otv Optical Borehole Televiewers Imaging Tool High Resolution Borehole Wall Interpretation Tool Geotechnical Rock Structure Imaging Device
The Optical Borehole Televiewer (OTV) is a valuable imaging tool that provides high-resolution visualization and interpretation of the borehole walls. It offers detailed images of geological formations, fractures, and rock structures, enabling geoscientists and engineers to gain critical insights into subsurface conditions. By utilizing the OTV, professionals can enhance geotechnical assessments, reservoir characterization, and wellbore stability evaluations, supporting informed decision-making and ensuring the integrity and safety of borehole operations.
The main purpose:
1. Carry out full-hole wall imaging, video recording, and snapshot pictures of key parts of the borehole;
2. Measure the trajectory of the borehole in space and the actual depth of the borehole;
3. Observing the occurrence and development of fault fractures;
4. Observing the water-bearing faults, karst caves and caves, the location of the water outlet of the aquifer, etc.;
5. Observing and quantitatively analyzing the strike, thickness, inclination, dip angle of ore bodies such as coal seams, interlayer gangue and the degree of separation and cracks from the roof strata;
6. Measure the thickness, width, direction, dip and dip of the formation or various structures from the imaging plan;
7. Distinguish various geological structures such as ore body, rock mass, coal seam, gangue, layer;
8. It is especially suitable for the detection of coal mine roof geological structure, occurrence of coal seam, fault structure in front of working face, water-conducting fracture zone of overlying rock, etc.
9. It is suitable for the detection of drilling holes of various shapes and functions, such as horizontal holes, vertical holes, inclined holes, etc.; such as bolt bolt holes, gas drainage holes, drainage holes and geological exploration holes, etc.
1. High integration: system control, image acquisition, display and storage are highly integrated in the host;
2. Ease of expansion: the same host hardware system, equipped with in-machine software and probes with different functions, can realize functions such as borehole imaging, borehole peeping and borehole trajectory measurement, and realize multi-purpose machine;
3. High intelligence: The host has a built-in dual-core processor, and the image processing speed is 25 frames per second. Simultaneous acquisition of image data, depth data and spatial data of the location of the probe can ensure real-time automatic acquisition of panoramic images, fast and seamless stitching, automatic angle and depth correction, and real-time presentation of panoramic video images with clear and vivid images. Realize image stitching, video recording and screenshot synchronization;
4. High reliability: the whole system is highly integrated and has good stability; the whole instrument is sealed and has good water and dust resistance;
5. High-definition: the camera is a color low-light 700Lines, 0.1Lux, 1.3 million pixels; the intensity of the light source can be continuously adjusted to ensure clear imaging of various detection objects;
6. Wide viewing angle: The camera has a wide viewing angle and can achieve horizontal 360-degree panoramic imaging without focusing;
7. Good portability: the whole machine is small in size, light in weight, easy to carry;
8. Good operability: the whole system is simple to connect, easy to operate, and quick for beginners; the host can be used as an external U disk of the computer, and the data can be copied and pasted directly;
9. Low power requirements: the host is powered by a built-in high-capacity nickel-metal hydride battery, and the continuous working time of the host is not less than 10 hours;
