175℃ High Temperature Directional Sensor on Wireline Logging and Borehole Logging

Product Details

1.175℃ High Temperature Directional Sensor on Wireline Logging  and Borehole Logging

HNYN provides a wide variety of high temperature directional and logging sensors designed for oil and gas exploration in challenging hotter environments. Our sensors are used in wireline logging ,borehole logging, directional drilling, EM and pulse based MWD systems and in high temperature drilling applications for oil, gas and geothermal.

Our sensors feature rugged construction, high reliability, and high accuracy. Our sensors support two communication protocols for wide range of information from down hole to surface, including roll, inclination, azimuth, vibration, shock, and rotational data.

Introduction of the Directional Sensor- WL SERIES:

The directional sensors are designed to real time monitor well bore inclination, azimuth, motor angle tool face and down hole temperature. And technologies from HT accelerometers, magnetometers and thick film hybrid integrated circuit enables directional sensors to work in 175 ℃~200℃ down hole environment. Besides, they have more advantages such as smaller size, compact structure, better vibration resistance, and higher reliability. Specified sensor shape, outer connection mode can be designed according to various clients' requirements.
