| 112 | A method for the reconstruction of wells through the removal of the old casing by using a single reverse-circulation perforation and relative device | EP10425119.4 | 2010-04-14 | EP2378055A1 | 2011-10-19 | Cempini, Nicola; Chiarugi, Stefano |
The present invention refers to an innovative method for the maintenance/reconstruction of a well (1) through only one fluid reverse-circulation perforation and the relative device. In accordance with the method, a drilling device (3) is arranged on a well driller machine (20) comprising a perforating tube (4) provided with one or more cutting utensils (6, 6'). The perforation of the ground is then carried out in such a way as to dig a circular crown (11) substantially concentric to the well. At the same time, the descending of a delivery flow by gravity into the circular crown (11) in formation takes place with the contemporary aspiration along the tube (4) in such a way as to aspirate all the detritus existing around the old pipeline. The cutting utensils are arranged in such a way that, during all the perforation, the circular crown dug has such a diameter D as to entirely contain inside it the aggregate material (16, 17) arranged around the old well casing. It is therefore possible to realize in this way the perforation in a single sinking.

| A retractable drill bit system (10) comprises a drive sub (18) which is adapted for connection to a lower end of a drill (12), a tool (20) for installing and retracting drill bit segments (22) from the drive sub (18); and an insert (24) for selectively locking the bit segments (22) to an end of the drive sub (18) and releasing the bit segments (22). A plurality of recesses (5B) are formed about an inner circumferential wall at one end of the drive sub (18) and a landing seat (32) formed about the inner wall upstream of the recesses (58). The area of the interior wall between the landing seat (32) and recesses (58) is profiled with a series of tapered and level surfaces. The tool (20) includes a slidable cradle (176) extending from one end about which the bit segments (22) are held during installation and retrieval. The bit segments (22) being held in place about the cradle by an elastic band (198). The insert (24) is provided at one end with a series of keyways (218) which locate over the bit segments (22) when the bit segments are locked to the drive sub (18). The insert (24) is always retained within the drive sub (18). Bit segments (22) are carried by the tool (20) to the drive sub (18) and locked in place by the insert (24). The tool (20) can then be withdrawn and the drill (12) operated in the normal manner. To retrieve the bit segments (22), the tool (20) is relowered into the drill and then withdrawn a short distance to retract the insert (24) so that the bit segments (22) collapse back onto the cradle (176) and can then be withdrawn from the drill (12). | ||||||
