Product Introduction

This set of product can not only measure the data of inclination, magnetic azimuth, tool face etc of a certain section of the well trajectory, but also can be used for measuring these data of a specific measuring point at the well bottom, which is widely used in the measurement of the well trajectory during drilling in oil, geologic, coal and water conservancy industries etc.

Suitable well conditions:

Minimum inner diameter of drill tools>45mm

Downhole temperature<125℃

Downhole pressure<120MPa

Features of multi-shot electronic inclinometer:

1)         Precise measurement, reliable stable performance: Equipped with shock proof accelerometer, the probe is featured with high linearity, small temperature drift, good repeatability and other characteristics, thus can ensure precise measurement data.

2)         Particular Power-off protection: This function allows the instrument to continue work normally even if there is a sudden outage caused by special strong vibration or impact.

3)         Low power consumption design, long working hours: With the low power consumption design, a fully charged battery can guarantee a continuous working for more than 80 hours.

4)         Good resistance to impact and vibration: The instrument is radially and axially equipped with multistage buffering devices, such as rubber, springs, hydraulic anti-seismic shock absorber, which effectively improves the impact resistance as well as the vibration resistance of the instrument.

5)         Allow various measuring methods, wide adaptability: The same probe-tube can be used for multi-point as well as for fixed-point measurement. Equipped with different downhole protecting system, it is available for self-floating measurement, suspending measurement and dropping measurement. It is very easy for the drilling teams to manage the instruments and reduce their purchasing cost.

6)         Available for high temperature measurement and deep well measurement: Assembled with the thermal insulation component, the highest working temperature will reach up to 260℃ and the highest working pressure will be 120Mpa.
