In the extreme subsurface environment-characterized by pitch darkness, intense heat, and extreme pressure-conventional electronic components rapidly fail, often within mere minutes. Against this backdrop, a purpose-built storage solution maintains uncompromising performance: our high-temperature storage chips operate reliably in environments exceeding 200°C, capturing and safeguarding the critical data that directly determines the efficiency and success of oil extraction operations, specifically engineered to meet the stringent requirements of oil well logging.
Surviving the Extreme Heat: A Harsh Environment Challenge
The downhole environment for oil well logging is a "purgatory" for electronics: temperatures often reach 175–210°C, pressures exceed 100 MPa, and conditions include strong vibrations and corrosive fluids. Conventional chips suffer severe performance degradation and data loss above 125°C. Our dedicated high-temperature storage chips overcome these challenges through MCM thick-film hybrid integration technology:
Ceramic substrates and metal hermetic packaging enhance high-temperature resistance and reliability.
High-temperature-optimized memory cell circuit design ensures stable data storage above 200°C.
The "Underground Black Box" for Oil & Gas Exploration
In petroleum exploration logging operations, this high-temperature storage chip acts as an underground black box. Integrated into logging tool storage modules, it real-time logs dozens of geological parameters: formation resistivity, acoustic velocity, gamma rays, and more. After logging tools complete missions thousands of meters underground and return to the surface, technicians retrieve data via dedicated interfaces. This heat-tested, invaluable data directly reveals the location, thickness, and oil content of underground reservoirs-forming the scientific basis for drilling site selection and production strategy design.
Domestic Breakthrough & Engineering Success
China has independently developed high-temperature storage chips with 2,000+ hours of data retention at 210°C. In ultra-deep well exploration in the Tarim Basin, logging tools equipped with our domestic high-temperature storage chips operated continuously for 68 hours at 201°C, successfully acquiring complete imaging logging data from 8,000-meter-deep formations. This milestone breaks long-term reliance on imported chips in this critical field.
Future Evolution & Expanding Applications
As global oil and gas exploration targets deeper, hotter formations, high-temperature storage chips evolve toward higher operating temperatures, larger capacities, and lower power consumption. This "heart" that preserves data in extreme environments not only supports the petroleum industry's march into the deep Earth but also enables technology derivatives for geothermal exploration, aerospace detection, and other extreme-environment applications-continuously expanding humanity's boundaries of knowledge.
