Product Introduction                                     

The product is used in the drilling process to measure the inclination, magnetic azimuth, tool face and instrument temperature and other parameters at downhole(measurement point) during drilling process.

This instrument belongs to self-floating fixed-point series products.

Accurate, time-saving, safe and convenient!

Suitable well conditions:

Minimum inner diameter of drill tools>60mm

Downhole temperature<125℃

Downhole pressure<75MPa 

Benefits of self-floating operation mode                

1)         Time-saving—compared with suspending operation mode, self-floating way doesn't need mud circulation, which can save at least 30 minutes for each survey.

2)         Safe-- throughout the measurement process, you can always start the pump or lift and rotate the drill string. It won't affect normal work of pulling the drill string from the hole, thus avoiding the occurrence of sticking accidents.

3)         Simple and convenient—No winch or pulley wheel are needed. One person can complete the whole survey work.
