Abstract

A rotary drill bit assembly (1) suitable for directionally drilling a subsurface borehole the assembly (1) comprising a bit body (3) extending along a central longitudinal bit-body axis (8), and having a bit-body face (10) at its front end, wherein an annular portion of the bit-body face is provided with chip-making elements (12); a pilot bit (20) extending along a central longitudinal pilot-bit axis (32), the pilot bit (20) being partly arranged within the bit body (3) and projecting out of the central portion (14) of the bit-body face (10), a joint means (30) arranged to pivotably connect the pilot bit (20) to the bit body (3) so that the bit-body axis (8) and the pilot-bit axis (32) can form a variable diversion angle; and a steering means (40, 42, 45, 47, 55, 62) arranged to pivot the pilot bit (20) in order to steer.

Claims (15)

1. A rotary drill bit assembly suitable for directionally drilling a borehole into an underground formation, the drill bit assembly comprising:
a bit body extending along a central longitudinal bit-body axis, the bit body having a bit-body face at its front end and being attachable to a drill string at its opposite end, wherein an annular portion of the bit-body face is provided with one or more chip-making elements;
a pilot bit extending along a central longitudinal pilot-bit axis, the pilot bit being partly arranged within the bit body and projecting out of the central portion of the bit-body face, the pilot bit having a pilot-bit face at its front end provided with one or more chip-making elements;
a joint means arranged to pivotably connect the pilot bit to the bit body so that the bit-body axis and the pilot-bit axis can form a variable diversion angle; and a steering means arranged to pivot the pilot bit in order to steer, during normal operation, the direction of drilling.
2. A rotary drill bit assembly according to claim 1, wherein the joint means is a spherical joint means.
3. A rotary drill bit assembly according to claim 1 or claim 2, wherein the joint means is further arranged to torque-lock the pilot bit to the bit body.
4. A rotary drill bit assembly according to any one of claims 1-3, wherein the steering means, for drilling at a constant non-zero diversion angle, is arranged so as to pivot the pilot bit with respect to the bit body such that the orientation of the pilot-bit axis in space remains substantially constant during at least one revolution of the bit body about the bit-body axis.
5. A rotary drill bit assembly according to claim 4, wherein the steering means comprises a steering lever extending substantially along the pilot-bit axis from a contact arrangement with the joint means to a lever point within the interior of the bit body, arid wherein the pilot bit can be pivoted by changing the position of the lever point with respect to the bit body.
6. A rotary drill bit assembly according to claim 5, wherein the steering means further comprises a rotation means connected to the bit body, and wherein the lever point is set to remain substantially at its point in space by the rotation means which is arranged to rotate the lever point relative to the bit body about the bit-body axis, at constant offset from the bit-body axis, in opposite direction and with the same angular velocity as the rotating bit body.
7. A rotary drill bit assembly according to any one of claims 5-6, wherein the contact arrangement with the joint means comprises a bearing arranged to allow rotation of the joint means about the pilot-bit axis relative to the steering lever.
8. A rotary drill bit assembly according to any one of the previous claims, wherein the steering means further comprises a steering control means arranged to control the direction of the steering lever during normal operation.
9. A rotary dill bit assembly according claim 8, wherein the steering control means comprises one or more of: a directional sensor package, a surface communications package, a rotation means for rotating the lever point about the bit-body axis.
10. A rotary drill bit assembly according to any one of the previous claims, wherein the bit body is provided with a passageway providing fluid communication between the interior of an attached drill bit and the well bore exterior of the bit body, and with a removable closure element arranged to selectively close the passageway, wherein the closure element comprises the pilot drill bit.
11. A rotary drill bit suitable for directionally drilling a borehole into an underground formation, the drill bit comprising a bit body extending along a central longitudinal bit-body axis, the bit body having a bit-body face at its front end and being attachable to a drill string at its opposite end, wherein an annular portion of the bit-body face is provided with one or more chip-making elements;
a pilot bit extending along a central longitudinal pilot-bit axis, the pilot bit being partly arranged within the bit body and projecting out of the central portion of the bit-body face, the pilot bit having a pilot-bit face at its front end provided with one or more chip-making elements; and a joint means arranged to pivotably connect the pilot bit to the bit body so that the bit-body axis and the pilot-bit axis can form a variable diversion angle.
12. A method for directional drilling of a borehole into an underground earth formation, comprising the steps of - providing a rotary drill bit attached to the lower end of a drill string, the rotary drill bit comprising a bit body extending along a bit-body axis coaxial with the lower part of the drill string, and having a bit-body face at its front end, wherein an annular portion of the bit-body face is provided with one or more chip-making elements, and a pilot bit extending along a pilot-bit axis and projecting out of the central portion of the bit-body face, the pilot bit having a pilot-bit face at its front end provided with one or more chip-making elements; which pilot bit is pivotably arranged with respect to the bit body so that the bit-body axis and the pilot-bit axis can form a certain diversion angle;
- setting the pilot bit along the pilot-bit axis at a selected diversion angle with respect to the bit-body axis;
- providing at the same time drilling torque around the pilot-bit axis to the pilot bit and drilling torque around the bit-body axis to the bit body, and wherein the orientation of the pilot-bit axis in space is kept substantially constant during at least one revolution of the bit body about the bit-body axis.
13. Method according to claim 12, wherein the pilot bit and bit body are torque-locked.
14. Method according to claim 12 or 13, wherein the diversion angle is steplessly varied, in order to drill into along a certain trajectory.
15. Method according to claim 12 or 13, wherein the diversion angle is varied by switching between zero and a predetermined non-zero diversion angle, in order to drill along a certain trajectory.
