In oil and gas extraction operations, downhole and gathering systems are continuously subjected to complex working conditions including high temperature, high pressure, severe corrosion and easily solidified crude oil. Real-time acquisition of temperature parameters is critical for reservoir characterization, production scheme optimization and the efficiency of production maintenance. Temperature sensors feature high sensitivity, fast response and superior measurement accuracy. They can be deployed deep inside oil wells to continuously monitor the temperature field of reservoirs and wellbores, enabling customers to accurately identify downhole conditions, optimize production parameters and arrange inspection, maintenance and repair in a scientific manner. To meet such demands, we offer a complete product portfolio ranging from sheathed thermocouples and high-precision platinum resistance thermometers to ultra-long temperature-measuring cables and mineral-insulated heating cables. Our products are widely applied in key scenarios such as permanent downhole temperature monitoring, temperature measurement at wellheads and gathering pipelines, heat tracing & thermal insulation for long-distance crude oil transmission pipelines, as well as temperature control for storage tanks and oil-gas processing units. Supported by manufacturing processes comparable to international standards and large-scale mass production capacity, we deliver reliable thermal sensing and thermal management solutions to support safe, efficient and stable production of oil and gas extraction.
