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>57mm

Downhole temperature<260℃

Downhole pressure<120MPa

Features of Fixed-point inclinometers:

Fixed-point instrument can start measuring as long as the instrument arrives at the well bottom. Compared with traditional timing measurement mode, it obviously saves the survey time, reduces the drill cost, and guarantees a successful measurement data in just one shot.

1)        Navigation software, precise guidance: the navigational controller will guide the user to operate the instrument with proper and accurate tips, which can guarantee a successful measuring data in just one shot and saves a lot of time.

2)        Accurate response, screw measurement: When the instrument arrives at the measurement point, mark the transitory quiescent time from the rest of the drilling tools to the float-up time of the instrument after the pump stops, thus it will realize the accurate measurement under screw drilling condition.

3)        No need timing, simple operating steps: Technicians no longer need to worry about how long the timing should be.

4)        Avoid hurried operation: No hurried preparation work before the instrument down into the well.

5)        No need to wait, start survey while arriving at the bottom: The instrument will start survey once it arrives at the well bottom.

6)        Reliable and with high stability: It will avoid measurement failure caused by short timing.

7)        Time-saving, Cost-reducing: This instrument can remarkably reduce the survey time, which lowers a lot of drilling cost for the drilling teams.

8)         Avoid washout, prolong life: There is no need to wait, so it reduces the mud flushing time to the carrier after it arrives at the well bottom.
