| Abstract: | Hole-deflection is a common problem in drilling, especially in deep well drilling. It has an important effect on the quality of a borehole and the safety of drilling. The reasons for hole-deflection and the principle of anti-deflection is analyzed in this paper. The principles, structure and the calculating ways of related specifications of the spired stabilizer and collar combination of packed hole anti-deflection drilling tool are also introduced. Based on practical engineering examples, the application of the techniques to well drilling in deep-seated bedrocks is discussed, the effects of the techniques to its anti-deflection is analyzed and the characteristics and application prospectives of the techniques are also summarizd. |
| Keywords: | hole-deflection stabilizer packed hole anti-deflection water-well drilling |
