ABSTRACT:
The apparatus includes a mast, an elevator and a tubing spider for suspending a string of well tubes or rods, a rack for storing well tubes or rods, a manipulator and a swivel head for screwing and unscrewing the string carried by the manipulator boom. To axially align the last tube or rod with the string the apparatus is provided with centering guides for centering the upper and the lower ends of the tube or rod and a gripping device for gripping the upper end of the string. The centering guide for centering the upper end of a well rod or tube forms part of a lifting frame, which in turn is a constituent of the elevator for suspending a string of well tubes or rods. The centering guide for centering the lower end of the rod or tube forms part of an automatic tong assembly for making up and breaking out joints of rods, which assembly is used with the claimed apparatus and also comprises the swivel head and the means for gripping the upper end of the string of well tubes or rods.
