Open hole logging services

Open hole logging technology is an important method for underground oil and gas exploration. It involves using instruments that reflect various physical properties such as heat, sound, electricity, light, magnetism, and nuclear radioactivity to measure the different physical characteristics of formations in a drilling well. By processing and interpreting this data based on their respective physical principles and interrelationships, it helps identify the porosity, permeability, fluid properties, and distribution of underground rocks. This information is crucial for discovering oil and gas reservoirs, assessing reserves, and predicting production rates. Our company specializes in conventional logging services for vertical, directional, and horizontal wells, as well as special logging services (dielectric scanning logging, elemental capture logging, nuclear magnetic logging, cross-dipole acoustic logging, micro-resistivity imaging logging, pressure-controlled closed chamber coring), and wellbore quality logging operations and data processing and interpretation.

Detection System

Conventional Instruments

Excellent interchangeability: The system's communication protocols, measurement accuracy, mechanical interfaces, and software operations are fully compatible with the ECLIPS-5700 logging system. Any downhole tools corresponding to the ECLIPS-5700 system can be completely interchangeable, meeting or exceeding the performance of the 5700 logging instruments.
Downhole tool joints and circuit housings are made of titanium alloy, while the threads are made of aluminum bronze, making the instrument lightweight, non-sticky, and reducing operator fatigue.
Instrument length reduced by 5.06 meters, enhancing safety.
Utilization of 296℃ soldering improves instrument reliability.
Product designed for bare frame operation at 175℃, pressure-resistant up to 140MPa, allowing for extended downhole operations, especially suitable for horizontal wells and long-term continuous logging compared to the original ECLIPS-5700 logging tool.
Available in various series: Φ70 small diameter, Φ89-175℃, Φ89-200℃-170MPa.
