Intelligent Pressure-Measurement Solution for High-Temperature and High-Pressure Downhole Conditions
Core technology
In the petroleum industry, downhole high-temperature and high-pressure measurement is a core technology that runs through the entire lifecycle—from oil and gas exploration and evaluation to production and enhanced recovery. The accuracy and reliability of the data obtained directly affect drilling safety, reserve estimation, and asset efficiency. However, the extreme operating conditions at depths of several kilometers underground—ranging from ultra-high temperatures exceeding 150°C to 200°C, ultra-high pressures above 70 MPa to 140 MPa, intense vibration and shock, as well as severe corrosion caused by H₂S, CO₂, and highly mineralized brines—pose significant challenges to measurement instruments. Traditional technologies, plagued by limitations such as creep, hysteresis, material susceptibility to corrosion, and inadequate thermal management, struggle to meet the demands for long-term stability and reliability, thereby reducing data credibility and directly impacting operational safety and resource extraction efficiency.
Based on this, Sensor Nobleman has launched an intelligent downhole pressure-measurement solution designed for high-temperature and high-pressure environments. At the heart of this solution is our independently developed high-performance nanofilm sensing technology. By achieving atomic-level bonding between specialized sensitive materials and metallic elastomers, we have fundamentally eliminated zero-point drift, enabling ultra-low long-term drift and exceptional thermal stability. Combined with corrosion-resistant alloy materials and an integrated, robust design, the product boasts outstanding resistance to corrosion, overload, and vibration and shock. We are committed to providing highly reliable, all-weather pressure data support throughout the entire operational process—from drilling and well logging to completion and enhanced oil recovery—helping our customers significantly improve operational safety and efficiency as they develop deep-layer oil and gas resources.

Core technology
The core nanofilm technology independently developed by Sensor Nobleman serves as the fundamental guarantee for achieving breakthroughs in the aforementioned high-performance measurement solutions. This technology deeply integrates key processes such as specialized metallic elastomers, novel sensitive materials, and vacuum atomic film deposition, enabling end-to-end independent design and manufacturing—from sensitive chips to finished sensors. Sensors based on this core technology not only ensure high precision, low drift, and a wide operating temperature range but also achieve generational improvements in long-term stability, tolerance to extreme environments, and overall reliability. As a result, these sensors can precisely meet the diverse needs of demanding downhole applications such as logging-while-drilling, permanent monitoring, and fracture monitoring, providing a stable and reliable data foundation for the construction of smart oilfields.
