Near-bit geo steering drilling technique 


1.Short blind area measurement, Zero-Length measurement 2-3cm, Near- bit resistivity can measure within 0.7m. 

■ Geological parameters: drill resistivity, azimuth resistivity, natural gamma ray 

■ Engineering parameters: well deviation,  tool face 

2. High resolution instrument, quick data transmission (50-60S) 

3. Has strong signal processing and recognition capacity, the signal can pass through more than 4500m. 

4. Working temperature 125℃(257℉), pressure 140MPa,continuous operation time ≥ 200h. 


Conventional LWD (MWD) sensor is mounted on the screw drill inside the non- magnetic drill collar. 

From Resistivity Probe Point to the drill 8-9m. 

From Gamma ray measure point to drill 13-15m. 

From Well deviation, azimuth measure point to drill 17-21m.
