| The present invention is for a drill string stabiliser tool (18) used in borehole drilling. The tool includes a symmetrical body (20) with a plurality of external recesses (22). The recesses (22) have internal opposite surfaces (23) which converge inwardly from the outer surface of the body. A pad assembly (24) is disposed in each recess (22) and includes a wedge block (28) with converging radially inwardly opposite side surface (29) complementarily abutting said recess surfaces. Each wedge block (28) has a bolt (30) securing said wedge block (28) to said body (20) and is slightly larger dimensioned than the recess (22). The angles of the wedge blocks and the recesses are so chosen to effect an interference fit so that when the wedge block (28) is forced into the recess (22) by use of the bolt (30) it is held there by an interference fit. | ||||||
| 197 | Torque reducing tubing component | US10451197 | 2003-06-19 | US20040060699A1 | 2004-04-01 | Gholam Rastegar |
| A torque reducing tubing component for insertion in a tubing string to be used in a bore hole. Upsets (22,30,24,26,28) are mounted on the outer surface of the component which reduce the contact between the tubing string and the bore hole wall thereby reducing friction between the tubing string and the bore wall. Grooves (46) on the upsets act to channel fluid around the upsets creating a fluid bearing film between the contact points of the tubing string and the bore wall. A pressure differential is also created around the upsets serving to attract fluid away from the bore wall so improving the efficiency of the circulation of fluid to the surface. Particular reference is made to a torque reducing tubing component for use in a drill string which improves the efficiency of cuttings removal. | ||||||
