Definitions
- a first solution to this problem is a device with the features of claim 1.
- the flexible section forms a discontinuity in the housing of the rotary drilling tool, through which the bend of the housing is localized during directional drilling and the other areas of the housing including its connection to the Bending stresses are relieved from the drill string.
- the localization of bending stresses in at least one second or further stabilizer arranged near the first stabilizer also reduces the lateral forces in the area of the stabilizers and thus the friction between the borehole wall and the stabilizers, which are accordingly subject to less wear.
- FIGS. 7 to 11 show exemplary embodiments based on an eccentrically designed second stabilizer 8 arranged in the upper region of the housing 2.
- the second stabilizer 8 each consists of a carrier body 18 and a rib sleeve 19 which can be fixed on the carrier body 18 by a positive connection . In the alternatives shown in FIGS.
- the rib sleeve 19 can be aligned in steps relative to the carrier body 18.
- the positive connection between the parts 18 and 19 is formed in the embodiment in FIG. 7 by a spline toothing and in that in FIG. 8 by a spur toothing 21.
- the second stabilizer 8 can also be designed to be adjustable.
- the first, central stabilizer 7 is matched to the dimension of the borehole diameter, while the second, eccentric stabilizer 8 is designed with undersize in order to prevent the deflection of the To compensate housing 2 and the output shaft 5 resulting inclination change tendency.
