ZITN DS360 175℃Dynamic Rotational Directional Sensor is a high-performance sensor engineered for demanding Measurement-While-Drilling (MWD) environments. Designed specifically for the drilling process, it operates reliably under extreme conditions-including rotation speeds of up to 150 rpm and strong vibrations of 6g-overcoming the limitations of traditional static surveys performed with pumps off and enabling true continuous surveying.
By integrating a high-precision 3-axis fluxgate magnetometer and a 3-axis accelerometer, ZITN DS360 175℃Dynamic Rotational Directional Sensor delivers continuous, real-time, and reliable measurement of key borehole trajectory parameters, even during high-speed drill string rotation and under intense vibration.
Application
- Measurement-While-Drilling (MWD): Provides real-time borehole trajectory data during the drilling process.
- Directional Drilling: Used for precise control of the wellbore path, especially in horizontal and extended-reach wells.
- Geosteering: Provides accurate azimuth and inclination data to ensure the drill bit remains within the target geological formation.
- Real-time Drilling Condition Monitoring: Assists engineers in interpreting downhole conditions and optimizing drilling parameters by providing RPM and stick-slip ratio.
Features
High Dynamic Accuracy under 0-175℃:
±0.1° Inclination, ±0.3° Azimuth, ±0.2° GTF. Maintains ±0.2° inclination even with stick-slip <60%.
Rugged Dynamic Performance:
Reliably operates while rotating (150 rpm) and under severe vibration (6g). Enables true continuous surveying.
Comprehensive Data:
Outputs all core (Inc, Az, GTF) and extended parameters (RPM, Stick-Slip, etc.) for complete downhole insight.
Efficiency & Safety:
Real-time data enables instant decisions and early warnings, boosting efficiency and protecting equipment.
Robust Construction:
Built to withstand extreme shock and vibration.
