Measurement while drilling in horizontal Wells |
Technical features:
1. Short blind area of measurement, 2-3m of zero length, and the resistivity of near bit can be detected within 0.7m below the bit.
￭ geological parameters: bit resistivity, azimuth resistivity, azimuth natural gamma
￭ project parameters: inclination and tool surface.
2. High resolution and fast data transmission speed (50-60s)
3. Strong signal processing and recognition ability, capable of transmitting more than 4500m.
4. operating temperature 125℃, pressure 140MPa, continuous working time ≥200h.
Conventional LWD sensors are installed in non - magnetic drill collars above the screw drill.
Resistivity detection points are 8-9m from the bit.
The gamma measuring point is 13-15m from the drill bit.
The deviation and azimuth measurement points are 17-21m from the bit |
