Abstract
A steering assembly includes a housing having a longitudinal axis, a mandrel having a front connecting extremity and a rear connecting extremity, the mandrel passing through the housing and arranged in a first position coaxially to the longitudinal axis of the housing, a deflector device configured to exert a side force on the mandrel to offset the front connecting extremity of the mandrel from the longitudinal axis, and a tool face assembly configured to rotate the front connecting extremity of the mandrel in a desired direction.
Claims (20)
1. A steering assembly, comprising: a housing having a longitudinal axis; a mandrel configured to pass through the housing; and a deflection assembly configured to deflect the mandrel relative to the longitudinal axis, wherein the deflection assembly comprises: a deflection sleeve configured to deflect the mandrel based on a position of the deflection sleeve along the longitudinal axis within the housing; and a ring gear configured to translate the deflection sleeve along the longitudinal axis to the position.
2. The steering assembly of claim 1, wherein the deflection assembly further comprises: a deflection motor configured to drive a deflection gear, wherein the deflection gear is configured to engage with an outer surface of the ring gear, and wherein the outer surface is geared.
3. The steering assembly of claim 1, wherein the ring gear is configured to rotate around the deflection sleeve and the mandrel in order to translate the deflection sleeve.
4. The steering assembly of claim 1, wherein the deflection assembly further comprises: a lead screw having an outer diameter threadably coupled to an inner diameter of the ring gear, wherein the ring gear is configured to translate the lead screw along the longitudinal axis as the ring gear rotates around the deflection sleeve.
5. The steering assembly of claim 4, wherein the lead screw and the ring gear are disposed within a volume of hydraulic oil within a sealed portion of the housing.
6. The steering assembly of claim 4, wherein the lead screw is configured to rotate around the deflection sleeve as the lead screw translates along the longitudinal axis.
7. The steering assembly of claim 6, wherein the lead screw is configured to move the deflection sleeve along the longitudinal axis as the lead screw translates along the longitudinal axis.
8. The steering assembly of claim 7, further comprising: a tool face sleeve coupled to the deflection sleeve and configured to be arranged around the mandrel, wherein the tool face sleeve comprises an inclined bore having a bearing carriage disposed therein, and wherein the bearing carriage is configured to deflect the mandrel relative to the longitudinal axis based on a position of the bearing carriage within the inclined bore.
9. The steering assembly of claim 8, wherein the deflection sleeve is coupled to the bearing carriage, and wherein the deflection sleeve is configured to change the position of the bearing carriage within the inclined bore when the deflection sleeve translates along the longitudinal axis.
10. The steering assembly of claim 8, wherein the tool face sleeve and the deflection sleeve are configured to change a tool face angle of the mandrel when the tool face sleeve and the deflection sleeve rotate about the longitudinal axis.
11. The steering assembly of claim 10, wherein the deflection sleeve is configured to rotate about the longitudinal axis independently of the lead screw rotating around the deflection sleeve.
12. A steering assembly, comprising: a housing having a longitudinal axis; a mandrel configured to pass through the housing; and a deflection assembly configured to deflect the mandrel relative to the longitudinal axis, wherein the deflection assembly comprises: a deflection sleeve configured to deflect the mandrel based on a position of the deflection sleeve along the longitudinal axis within the housing; and a lead screw configured to translate the deflection sleeve along the longitudinal axis to the position.
13. The steering assembly of claim 12, wherein the deflection assembly further comprises: a ring gear driven by a deflection motor, wherein the ring gear is configured to rotate around the deflection sleeve and the mandrel in order to translate the deflection sleeve.
14. The steering assembly of claim 13, wherein the lead screw and the ring gear are disposed within a volume of hydraulic oil within a sealed portion of the housing.
15. The steering assembly of claim 13, wherein the lead screw has an outer diameter threadably coupled to an inner diameter of the ring gear, wherein the ring gear is configured to translate the lead screw along the longitudinal axis as the ring gear rotates around the deflection sleeve.
16. The steering assembly of claim 13, wherein the lead screw is configured to rotate around the deflection sleeve as the lead screw translates along the longitudinal axis.
17. The steering assembly of claim 13, wherein the deflection sleeve is configured to rotate about the longitudinal axis independently of the lead screw rotating around the deflection sleeve.
18. A method, comprising: providing a steering assembly in a drill string, wherein the steering assembly comprises: a housing having a longitudinal axis; a mandrel configured to pass through the housing; a deflection assembly configured to deflect the mandrel relative to the longitudinal axis, wherein the deflection assembly comprises: a deflection sleeve configured to deflect the mandrel based on a position of the deflection sleeve along the longitudinal axis within the housing; and a ring gear configured to translate the deflection sleeve along the longitudinal axis to the position; and operating the deflection assembly to deflect the mandrel relative to the longitudinal axis.
19. The method of claim 18, wherein the deflection assembly further comprises: a lead screw having an outer diameter threadably coupled to an inner diameter of the ring gear, wherein the ring gear is configured to translate the lead screw along the longitudinal axis as the ring gear rotates around the deflection sleeve.
20. The steering assembly of claim 19, wherein the deflection sleeve is configured to rotate about the longitudinal axis independently of the lead screw rotating around the deflection sleeve.
