Measurement While Drilling (MWD) refers to the technology of measuring relevant downhole engineering and geological parameters in real-time during the drilling process and transmitting the data to the surface system via wireless transmission technology.
n the grand narrative of oil and gas exploration and development, rock formations thousands of meters underground are like a heavy, secret tome. How to interpret this tome, accurately locate oil and gas reservoirs, and efficiently develop subsurface resources? Wireline Logging and Directional Sensors play indispensable roles—they act as the geologists' "eyes" and "compass," one responsible for sensing the physical and chemical properties of the formations, and the other for precisely navigating the orientation of downhole tools.
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.
