Abstract
Method for positioning and anchoring recovery columns in oil wells in which the recovery column is lowered, maintaining a circulation of fluid, until the increase in the pressure of the fluid indicates that the foot has fitted into the liner, one continues until the fit is complete and the column is lifted again by an amount greater than the length of the foot, the cementing is done, and then the anchoring devices are applied, in which when the column is completely lowered one identifies the position in which the anchoring devices are supposed to be applied and these latter are opened and locked around the column at the point identified, when the column is lifted and without lifting the well head. The invention also concerns anchoring wedges to implement said method. <IMAGE>
