In petroleum logging, equipment often operates under extreme conditions such as high temperatures and vibrations, making a stable and reliable power supply critical for device performance. As global oil and gas resource exploration advances into deeper strata, the temperature underground rises by approximately 30°C for every 1,000 meters of depth. As a core component of high-temperature drilling equipment, the high-temperature reliability of power supply products directly impacts the performance of drilling systems. From the stable operation of downhole motors to the accurate transmission of signals, every aspect relies on power supplies with stable performance and high-temperature resistance.
In this groundbreaking endeavor to push the limits of deep-earth exploration, ZITN provided critical technical support with its 250°C high-temperature dual-channel linear power supply product, ensuring stable operation of logging instruments under extreme conditions and guaranteeing the accuracy and reliability of data acquisition.
LH42095-250 series of exact negative regulators are technically designed to use in high temperature and wide temperature range environments. The output voltage of these regulators will not change along with the input voltage,the load current and the temperature of the environment.These regulators will operate reliably in high case temperature 250℃ without external filter capacitance.The output voltage and output current of these regulators can both be regulated independently. These regulators require few peripheral components,and can be used expediently and simply in all kinds of negative power supply, specially in the electronic equipment operating in high temperature and wide temperature range environments.
ZITN will celebrate the 2025 Spring Festival from January 25th to February 4th. Wish you have a very happy and prosperous New Year.
ZITN TECH 2025 annual celebration was held successfully.
ZITN new developed 175℃ MWD tools just finished its first drilling operation in the oil well last week. It is performance well from 297-1330m in the well without any error. It is a gid process of ZITN.
The ZTMWD-48 system consists of a surface decoding system and downhole instruments. All circuits in the downhole instruments are manufactured using high-temperature Multi-Chip Module (MCM) technology, which enhances reliability and lifespan in high-temperature and high-vibration environments while reducing the instrument size. The directional probe integrates self-developed accelerometers and fluxgate sensors, combined with high-precision compensation and calibration algorithms, enabling accurate inclination and azimuth measurements across the full temperature range. Additionally, it supports rotary inclination and azimuth measurement, improving directional drilling efficiency.
