<p>A temporary support device for oil well tubes and method of use. The device comprises a holding structure (10) to be applied to the well surface casing (1), a holding base (20) resting on the well's cellar floor (40) and sets of adjustable supporting arms (30) connecting said holding structure (10) and said supporting base (20). The supporting base (20) is assembled and placed on the well's cellar floor (40) and the holding structure (10) is arranged around the upper end of the casing (1), alone or along with the tubular application device (2, 4, 5). Thereby, casing (1) is supported by the device of the invention. This supporting action is temporary until some operation is carried out and/or cementation and setting of the region surrounding tube (1) is produced, causing the tube to be permanently fixed in place. The method is comprised of a series of steps through which the supporting base (20) is placed, the holding structure (10) is mounted, positional regulation arms (31) are actioned, positional fixing arms (35) are arranged; and the device remains active, at least, during the period of time during which the operation lasts or until cementation of the tube (1) takes place.</p> |
