Study of the performance of measurement microelectronics in low-temperature climatic conditions

ACTUALLY. The work addresses the topic of using electronic measuring devices in the drilling process of wells under particularly challenging and unique conditions in Antarctica. In the context of extremely low temperatures, characteristic of this region, the task is to ensure the reliable operation of electronics, which is critically important for the successful execution of drilling operations and obtaining accurate data. Special attention is given to analyzing various methods for protecting electronic devices from negative temperatures. Numerous approaches to thermal insulation are explored, and innovative materials are utilized to minimize the impact of cold air on sensitive electronic components. OBJECT. The aim of the work is to investigate current electronic measurement systems used in drilling wells under Antarctic conditions, as well as to conduct experiments on series temperature sensors using a cooling chamber. METHODS . The study includes thorough experiments with temperature sensors of various types and formats. Testing was conducted in specialized cooling chambers, allowing for the modeling of real conditions faced by devices in Antarctica. Furthermore, the study examines the impact of the sensor placement relative to the microchips, which can significantly affect their accuracy and reliability. An important part of the work was an experiment with electronics covered by a waterproof polymer coating. This coating not only protects the devices from moisture but also provides additional insulation against cold, which is of paramount importance in Antarctic conditions. RESULTS. Thus, the results obtained allow conclusions to be drawn about the most effective ways to protect electronic measuring devices for drilling in challenging climatic conditions, as well as opening new horizons for further research in this area.
