Product Introduction

Key Features

Near-bit inclination and azimuthal gamma imaging.

Remote adjustment of post-screw centralizer size, enabling drilling assembly adjustments without tripping.

Automatic retraction of the centralizer during tripping or in complex downhole conditions, avoiding risks such as stuck pipe.

Industry's shortest near-bit measurement sub, only 0.5 meters, reducing borehole enlargement rate and downhole risks.

Electromagnetic coupling communication, reliable transmission, adaptable to any mud or formation.

Single battery operating time: 360 hours, with the option to use two battery sets.

High-temperature, oil-resistant, equal wall thickness, high-power screw, with a maximum operating temperature of 175°C.
