| Abstract: |
| According to current actual needs of measurement-while-drilling, a special power supply method ??based on the external power which is supplied to the inclinometer probe is described in this paper. Changing the measurement-while-drilling equipment"s power supply method and saving time by this method. The entire configuration of the system is designed, and through test show that the improved measurement-while-drilling system can get inclination、azimuth and tool face angle and other parameters while drilling, the technology has a leading position in the world, and at the same time it fills the domestic and abroad blank in measurement-while-drilling equipment. |
