Abstract
An elevator usable on a drilling rig is modified by attaching a swing arm and related structure to at least one accessory mounting provision on the elevator. The swing arm is tiltable to allow a single section elevator, carried by the swing arm, to engage a pipe extending near the well centerline. While the pipe section is being lifted, the swing arm pivots to allow the section to assume a vertical position under the elevator. When the pipe section is being rotated to run threads to join the section to the string the swing arm can extend to accommodate thread-run dimension changes. An elevator equivalent, without pipe gripping features, may be used.
Description
- This invention pertains to apparatus for handling pipe and pipe strings in well drilling and servicing processes, including connection of pipe sections to pipe strings suspended in wells.
- During drilling and casing of wells, a pipe string is assembled by adding stands of pipe, consisting of one or a plurality of pipe sections, to pipe strings. The pipe strings extend through the drilling floor rotary opening and continue downward into existing well bores. The pipe string being assembled may be drill strings or casing strings, and occasionally other tubular strings.
- The rate of the pipe string assembly is part of the well drilling time involvement and can amount to many hours of total well producing time involved. Cost reduction, involves time reduction in pipe string assembly.
- Well production time, in terms of drilling rate, has been addressed with great earnest for many years. Pipe string assembly rate has about the same cost effectiveness as drilling rate. This invention addresses the reduction of costs, and does so within the safety concerns common to well bore production and production expected of completed wells.
- For safety reasons, the use of personnel in contact with tubulars during pipe string assembly on the derrick floor is being minimized. Full mechanization of such activities on the derrick floor is not always possible but every effort to limit the contact between the more dangerous activities and people is worthwhile.
- Offshore drilling rigs are usually massively complex and costly and the addition of machinery approaching automatic functions is not an expense that is a large percentage of the overall costs. On smaller on-shore rigs, the complex machinery is not readily adaptable and the reduction of contact between men and machinery is approached with simpler apparatus such as the present invention.
- An elevator is modified to accept swing arms and related manipulating gear. The preferred elevator has a mounting ring on the lower face to accept a pipe guide. The pipe guide is replaced by a mounting base which is secured to the mounting ring. The mounting base has a lower mounting ring to which the pipe guide can be attached.
- To prevent destructive loads on the elevator mounting ring, the mounting base is provided with security structure that engages the elevator elsewhere on its structure.
- In the preferred configuration, the mounting base has a pivot axle extending horizontally from opposite sides of the elevator to support a swing arm assembly to support a single section elevator. Optionally, the pivot axle may comprise the rotor of a motor.
- In one configuration, an actuator mounting bracket is attached to each pivot axle and extends upward to support tilt cylinders. An upper swing arm is attached to the pivot axle to pivot about a horizontal axis and is situated to be tilted by the tilt cylinders. The upper swing arm carries a lower swing arm which is arranged to carry a single section elevator. The lower swing arm is attached to the upper swing arm by extension riders which allow limited swing arm extension and may compensate for thread make-up. Extension of the swing arm is controlled by a linear motor, or cylinder, that is, preferably, fluid powered.
- The swing arm arrangement allows the single section elevator to be swung from the well axis to pick up a pipe section that extends toward the well axis. When the single section is lifted, it can swing to be aligned with the well axis to position it for make-up on the pipe string standing in a spider.
