It has previously been common in well drilling and other well operations to impart motive force to the drill string or other tubular members being worked with by means of the old rotary table drive apparatus or electric motor top drives. The old rotary drive tables are inefficient and costly. The electric top drives have had numerous problems; for example, to move and support drill strings weighing up to 500 tons, the Direct Current traction motors used in electric top drives must be very large, consequently they require a large and effective motor cooling system. Also all of the safety problems associated with electricity are considerations when using an electric top drive. Because of these shortcomings, obtaining compliance with accepted safety codes and insurance certification for the use of electric top drives has been a tedious, expensive, and time-consuming process. There are also numerous structural/functional disadvantages associated with the use of electric top drives; for example, one prior art electric top drive utilizes an expensive thrust bearing to support the drill string rather than using the shaft of the motor itself. Another prior art electric top drive has an electric motor which is offset from the shaft supporting the drill string which results in an imbalance in the distribution of the reactive torque applied.

The present invention is directed to an hydraulic top drive apparatus and tubular handling device that overcomes the problems associated with the prior art drives. Mounted beneath a conventional crown block, traveling block, bail, and swivel, the present invention includes an hydraulically powered top drive pipe rotating device having a single hollow shaft with threads at each end for mating on one end with the drill string or tubular to be worked and on the other with a drilling swivel. The top drive rotating device is attached to a wheeled support frame which moves on guide rails which are mounted to a derrick. The mounting of the top drive apparatus permits it to be pivoted in a horizontal plane away from the vertical axis of the drill string or other tubulars. Motive force is applied directly to the drill string or other tubular being worked. Also, the top drive is fully reversible so that motive force can be applied in either direction. A makeup/breakout wrenching device is pivotably connected to the wheeled support frame beneath the top drive. A pipe lifting and positioning device is mounted beneath the top drive on the wheeled support frame for picking up pipe and positioning it so that the pipe threads can mate precisely with the threads of the top drive shaft.

Yet another object of the present invention is the provision of means for pivoting the top drive apparatus in a horizontal plane away from the drill string or other tubulars being worked without having to tilt the top drive from the vertical.

A further object of the present invention is the provision of such a top drive apparatus in which its shaft itself supports the drill string so that no thrust bearing support is required.

Another object of the present invention is the provision of such a top drive apparatus in combination with a pipe lifting and positioning device, both of which are mounted on a wheeled support which in turn is mounted on rails connected to the derrick for moving the top drive apparatus and pipe positioning device up and down within the derrick.

Yet another object of the present invention is the provision of such a top drive in which the pipe positioning device can be pivoted in a horizontal plane away from the drill string or other tubular being worked without having to tilt it from the vertical.

Yet another object of the present invention is the provision of an hydraulic top drive apparatus which permits the lifting of the drill bit off the bottom of the hole when making connections of pieces of the drill string.

Still another object is the provisions of such a top drive with which drill pipe connections may be broken at any elevation in the derrick and which provides smooth rotary torque at any elevation.

Another object of the present invention is the provision of such a top drive which can be utilized for all normal drilling, reaming and casing operations, can be used to drill with single or multiple sections of pipe, and can ream in ninety-foot increments.

Other and further objects, features and advantages of this new top drive apparatus and pipe positioning device will be apparent from the following description of the presently preferred embodiments of the invention, given for the purpose of disclosure and taken in conjunction with the accompanying drawings.

Referring now to FIG. 1, an hydraulically powered drilling top drive apparatus 10 according to the present invention is suspended from a commercially available swivel 11 fitted with optional bail links 12 for counterbalancing. This swivel in turn is attached to a traveling block 13 which is attached by cables to a crown block 14 in the derrick 15. The top drive 10 is attached to a wheeled support frame 16 which is mounted upon guide rails 17 which are mounted to the derrick 15. The attachment of the drilling top drive 10 to the swivel 11 shaft may be made through a one piece threaded hollow shaft or by using a splined quick disconnect 18. The hydraulic fluid which operates the top drive 10 is conducted through pipes 19 and hoses 20 from a power unit 21 located at a convenient point. The top drive 10 has a hollow shaft with a threaded top end 30a for connection to the swivel 11.

The drilling top drive 10 is attached to the wheeled support frame 16 in such a manner that it may be rotated in a horizontal plane about pivots 22 on the wheeled support frames 16 for maintenance or removing from service. The drill pipe positioning arm 23 is also pivoted from the support frame 16 in such a manner that it may be rotated in a horizontal plane to a drill pipe pick-up point using cylinders 24. The positioning arm may then be rotated to a point which positions the drill pipe 66 directly over the centerline of the well being drilled. Additional cylinders 25 then elevate the drill pipe 66 to allow a screwed connection to be made to either: the threaded bottom end of the top drive shaft 30, the threaded bottom end of the elevator link adapter 27 (when it is used), or to the threaded end of the saver sub 67 when it is used. Since the motive force of the top drive is centered about the central shaft 30, the reactive forces are balanced and a concentric balanced force is imparted to the drill string.

Referring now to FIG. 2, the positioning arm bowl 33 is designed with a "U" shaped opening with a tapered seat to match the drill pipe tool joint. The latch arm 35 moves to allow the entry of drill pipe. The latch arm is spring loaded to the closed position. Drill pipe may be loaded by pushing into the opening 35a. A cylinder 36 is used to move the latch to the open position. Cylinder 25 when actuated, moves the drill pipe into contact with the mating thread on the top drive shaft 30. The latch may also be activated manually.

Referring now to FIG. 3, the hydraulically cushioned bail link has a piston 34 which acts upward in the cylinder barrel 36 as a result of fluid under pressure entering the interior of the barrel 36. This internal force acts like a compression spring. When the rod 34 is actuated downward by a load the potential energy is stored within the chamber 38. As long as the load is more than the potential energy, the distance between the attaching holes 43a and 43b will be at maximum. When the load is next reduced such as when a section of drill stem is unscrewed, the distance between the attaching holes will decrease, the drill string proper will remain stationary in the hole, the drilling swivel 11 will move upward as the threaded members of the drill string separate, while the section being unscrewed is raised by the action of the piston 34 within the barrel 36 to an upward position. When the load is entirely removed, the distance between the centers of the attaching holes will be at minimum. Packing seals 37 maintain the pressure required to move the piston.

Referring now to FIG. 5, the wrenching device upper section 26 has the box section g securely attached to support members a. Die block c is attached to inner die carrier d. Blocks b and c are able to move inward or outward on guides h. Cylinder k when pressurized in chamber q moves block b into contact with tubular workpiece m. As block b engages workpiece m a reactionary force moves inner die carrier d in a direction away from workpiece m until die block c which is attached to die carrier d is forced to engage workpiece m. In operation, pressure in chamber q creates a gripping force which firmly engages serrated dies s against the workpiece m. In the reverse action, cylinder k is pressurized in chamber r causing die block b to move away from workpiece m. After partial travel, block b will contact stops e which will cause the body of cylinder k and the inner die carrier d to move inward toward the workpiece m. This action forces the die block c away from workpiece m.

Referring now to FIG. 7 which is a bottom view of the lower, rotatable section 31 of the wrenching device, the box section g is securely attached to circular guide plate f. Die block c is attached to inner die carrier d with pins p. Blocks b and c are able to move inwardly and outwardly, being aligned by guides h. Cylinder k when pressurized in chamber q moves block b to contact tubular workpiece m. As block b engages workpiece m, a reactionary force moves inner die carrier d in a direction away from the workpiece m until die block c engages workpiece m. In operation, pressure in chamber q creates a gripping force which firmly engages serrated dies s against workpiece m.

Referring now to FIG. 6, the cylinders v are affixed to the lower section z of the wrenching device through a clevis aa at the rod end. The barrel end is connected to the upper section BB through a hinged joint w and the reaction is restrained by the upper section BB. When the cylinders are energized, the lower section will rotate the centerline of the guided die blocks about axis y. The annular groove and tongue u and x align and secure the upper and lower halves together while allowing rotary motion. When the bolts B are removed the wrenching device is free to pivot in a horizontal plane about Point P as shown in FIG. 1.

With this invention, well drilling fluids enter the drill string through a conventional flexible hose connected to the swivel 11 shown in FIG. 1. The swivel has a hollow shaft through which fluids pass into the hollow shaft 30 of the top drive 10 and on through the hollow sections of the remaining subs or devices into the interior of the drill string.

The top drive apparatus according to the present invention compare very favorably with the prior art drive apparatuses. The following chart compares certain features (but not all) of a top drive according to the present invention to the top drive embodying features disclosed in U.S. Pat. No. 4,449,596 and to the Bowen ES-7 Electric Drilling Swivel:
