Downhole Television

Product Overview

The downhole video inspection system is a modern downhole detection device integrating high-definition imaging, real-time transmission, and intelligent analysis technologies. Specifically designed for visual inspection of wellbore conditions in oil & gas wells, geothermal wells, and engineering wells, the system features a modular architecture capable of stable operation in high-temperature (≤175°C), high-pressure (≤100MPa), and highly corrosive fluid environments. It provides intuitive and reliable imaging data for wellbore integrity evaluation, fault diagnosis, and workover operations.

Core Technical Features

Ultra-HD Imaging System

Equipped with a 2-megapixel high-definition camera and adaptive LED lighting system (adjustable illumination 10-10,000 Lux)

360° rotating platform (angular resolution 0.1°) with motorized zoom lens (20× optical zoom)

Pressure-resistant housing constructed with aerospace-grade aluminum alloy and ceramic composite (IP68 protection rating)

Intelligent Diagnostic Functions

AI image processing algorithms for automatic detection of casing corrosion, deformation, perforations, and other defects (accuracy ±1mm)

3D wellbore modeling technology for quantitative analysis of crack width/depth

Historical data comparison function for dynamic corrosion rate evaluation

Multi-Mode Operation Capability

Supports three operation modes: wireline real-time readout, memory mode, and wireless transmission

Compatible with wellbore diameters from φ90mm to φ300mm (interchangeable centralizers included)

Maximum deployment depth of 3,000m (high-temperature/high-pressure enhanced version available up to 5,000m)

Typical Applications

Casing corrosion/scaling inspection in production wells

Perforation quality and completion tool status verification

Precise fish location identification and fishing program development

Wellbore repair effectiveness validation

Quality Assurance System

Certified to API 11D1/ISO 18164 standards

Full product line tested for H2S environment compatibility (NACE MR0175 compliant)

Equipped with wellbore simulation test equipment (adjustable pressure/temperature/fluid parameters)

This system transforms traditional "blind operation" downhole inspection into "visualized intelligent diagnosis," improving inspection efficiency by over 50% and providing critical technical support for well lifecycle management. Customized configurations including explosion-proof and ultra-high-temperature versions are available based on operational requirements.
