Drilling sensor / 鑽孔傳感器
Sensor for drilling applications
Sensing technologies are a crucial part of the Energy market, especially when it
comes to the Oil and Gas markets, with accelerometers being the most widely used
sensors across these industries, featuring various applications in drilling that
range from measuring inertia (directionnal drilling), vibration to the
monitoring of low-frequency seismic signals, angular tilt and shocks. Since the
Energy market is highly adaptible,MEMS accelerometers are
enjoying an increase in popularity, as their reliability and accuracy under
harsh conditions.
The MEMS sensor revolution
MEMS sensors are replacing the well-established, expensive and fragile
electromechanical devices and accelerometers made out of quartz used in high-end
Energy applications due to them being robust devices that offer the same or an
increased level of performance at a lower cost, a lower power consumption and a
smaller size. The success of Colibrys high-end MEMS accelerometers in this
market derives from the sensor’s ability to function properly under extreme
temperature up to 175°C, under high vibrations or strong shocks and , though,
insure a long bias stability.
Specific application for MEMS accelerometers in drilling
-
Precision tilt measurement in Down borehole MWD (measurement while drilling)
and logging
-
Inertial measurement within pipeline monitoring PIGs
-
Wirelin- logging
-
