A temporary support device for an oil well tube, to be installed at a well site, applied to the upper end of a well surface casing, adjacent to a tubular application device, the temporary support device comprising:
- a holding structure to be mounted around the upper end of the tube;
- a supporting base capable of being placed on a well cellar floor;
- adjustable support arms that connect said supporting base to said holding structure, said adjustable support arm providing means of positional, longitudinal and axial regulation of said casing;
- wherein there support arms provide for adjustable movement of the holding structure with respect to the supporting base after the holding structure is secured to an oil well tube;
- wherein the adjustable support arms each comprise a set of arms, in which each set is made up of at least one positional regulation arm and at least one positional fixing arm;
- and
- wherein each positional fixing arm has threaded longitudinal variation nut and counter nut means for positional locking.
