| 245 | Closed loop control system for diamond core drilling | US09209821 | 1998-10-22 | US06186248B1 | 2001-02-13 | Louis E. Silay; Raymond B. McKinley |
| A closed loop control system for a core drilling mechanism automatically controls the penetration rate, the weight on the drill bit, and the torque load applied to the drill string, and maintains all three at or below preselected maximum values. The closed loop control system incorporates a controller that receives sensed information and generates corresponding control signals to control the penetration rate and thus the weight on the drill bit and the torque load through a servo valve in a hydraulic drive circuit. One or more sensors are provided to sense the penetration rate of the drill bit, and are coupled with the controller.

| 252 | Pipe alignment device | US480749 | 1990-02-16 | US5033907A | 1991-07-23 | Hugh W. O'Donnell; Ahmed Ben Salah |
| An apparatus and method for underwater aligning and connecting of two pipes used in directional drilling and particularly trenchless beach crossings. An alignment cable is connected between the ends of the two pipes and is tensioned to bring them into axial alignment. A rigid supporting platform is positioned on the sea floor.

| 253 | Method and a drilling rig for drilling a bore well | US79769 | 1987-07-07 | US4850439A | 1989-07-25 | Thomas A. Lund |
| Drilling equipment, especially for offshore use, comprises a drill floor or platform (11) with a derrick (10) extending upwards therefrom. A first hoist (12) connected to the upper part of the derrick is used for passing a length of a tubular body (19), such as a drill string or a well casing, through a drilling opening (18) defined in and extending through the drill floor. The tubular length is connected to or disconnected from the drill string or well casing during the drilling operation, and such tubular lengths are strored in a storage area (31, 32) of the drill floor. The tubular lengths may be transported from the storage area to the first hoist (12) and vice versa by means of first transporting means (22). The drill floor or platform (11) also defines a preparation opening (21) extending therethrough at a location spaced from the drilling opening and from the storage area, and a second hoist or a preparation hoist (20) is connected to the upper part of the derrick above the preparation opening. Two or more tubular sections may then be assembled to tubular lengths at the preparation opening by means of the preparation hoist while the drilling operation is going on at the drilling opening, and the prepared lengths may be transported to and stored in the storage area ready for use at the drilling opening. Similarly, tubular lengths may be disassembled into tubular sections at the preparation opening before they are to be transported from the drilling site. The possibility of assembling and disassembling tubular lengths form tubular sections at the preparation opening while the drilling operation is going on at the drilling opening substantially reduces the necessary idle time in drilling operations. | ||||||
| 254 | Drill magazine | US110847 | 1987-10-21 | US4834195A | 1989-05-30 | Allen C. Robinson |
| An improved drill rod magazine for storing and moving them sequentially into a dispensing position is comprised of a pair of spaced arms each with an open jaw in which the drill rods are positioned in parellel, side by side relationship. The arms are moveable from a storing position into at least two dispensing positions, in a first of which one of the rods in the jaws is aligned with the hammer of the drilling machine and in the second of which another rod (the adjacent rod) is aligned with the hammer. Each of the jaws is provided with a clamp to clamp the rods contained therein to prevent rotation of each rod for threading of the hammer into an adjacent coupling on the rod. The rod is released for rotation while retaining same within the jaws so that the rod coupled to the hammer may be rotated and advanced by the hammer to thread same into an aligned coupling, after which the arms are retracted to their storage position. For uncoupling the procedure is reversed. | ||||||
| 255 | Active counterbalance for a power swivel during well drilling | US163580 | 1988-03-03 | US4813498A | 1989-03-21 | James E. Lynch; David B. Ford |
| An active counterbalance for suspending a power swivel from a traveling block. The power swivel includes a motor drive assembly for rotating a drill string and a handling system for supporting a drill pipe. The counterbalance includes a motor which provides means for biasing the load capacity of the counterbalance when supporting the power swivel to allow vertical displacement of the power swivel relative to the traveling block. The counterbalance prevents damage to connecting or sealing surfaces when adding pipe to or removing pipe from the drill string because most of the weight of the power swivel and pipe suspending from the handling system is transferred to the counterbalance. | ||||||
| 256 | Hydraulic top drive for wells | US38877 | 1987-04-14 | US4813493A | 1989-03-21 | Danial G. Shaw; Billy MacCline |
| Well apparatus including a top drive assembly having a hollow drive stem driven through a gear assembly by a plurality, two or more, of hydraulic motors, the drive stem adapted to be attached to a well swivel at upper end and an intermediate sub or a string at the lower end, the rotary motion of the drive stem to power the string during operations. A shut off valve to shut off well fluid and a link adapter can be located between the lower end of the hollow drive stem and the upper end of the drill string. The vertical axis of the drive stem can be aligned coaxially with the vertical axis of the wellbore and with the vertical axis of the drill string. The top drive can be mounted to a wheeled support frame contained within two elongated members mounted in a derrick. Pivotably mounted to the support frame is a manipulator arm adapted on one end to grasp and support a tubular member and pivotable in a horizontal plane. Also mounted to the support frame is a pipe wrenching device which is extendable toward or retractable from a position coinciding with the well centerline. | ||||||

| A well pipe handling machine including a vertically extending column structure which carries means for engaging and holding a pipe in vertical condition and is movable with the pipe holding means between a first position in which a carried pipe can be connected to and disconnected from the upper end of a drill string and a laterally offset second position for storing pipe in a rack at a side of the well. The pipe holding means may include a parallelogram mechanism having two arms carrying two vertically spaced pipe holding units and adapted to swing in unison to move the units toward and away from the column structure. The column desirably also carries pipe rotating means including a torque wrench and a spinner for making and breaking a threaded connection between a section of pipe and the string. The spinner is mounted for shifting movement upwardly and downwardly relative to the pipe holding means, and preferably is positioned at the lower end of an operator's cab which is also carried by the support column structure for movement therewith between its different positions. The torque wrench may be located beneath the spinner at the lower end of the control station, and is movable upwardly and downwardly with the spinner and cab relative to the pipe holding means. | ||||||
| 259 | Well pipe handling machine | US854404 | 1986-04-21 | US4696207A | 1987-09-29 | George I. Boyadjieff |
| A well pipe handling machine for removing a series of stands of pipe from the upper end of a well pipe string and storing the stands in a rack offset to a side of the well axis and/or returning the stands sequentially from the rack for reconnection to the string. The machine includes a support which carries means for holding a pipe in vertical condition and is movable between a position in which the pipe is in alignment with the well axis and a location near the storage rack, and which preferably takes the form of a vertically extending column structure movable horizontally by two synchronized drive mechanisms at the top and bottom of the column structure. The pipe holding means are desirably shiftable upwardly and downwardly relative to the support and also generally horizontally toward and away from the support for placement of the pipe stands in the rack and removal therefrom. The pipe holding means may include two vertically spaced pipe gripping units mounted by a parallelogram mechanism for movement toward and away from the support. The machine also may include apparatus for turning a pipe stand to connect it to or disconnect it from the string, with this apparatus being movable with the support and pipe holding units between the well axis and the storage rack. | ||||||
