Abstract
A downhole well tool (1) for orientation of a work tool (16) comprises an anchor (6), an energy unit (2) and a controller (22). The downhole well tool (1) is equipped with an axial displacement part (10) and a rotational part (14), where at least one of the axial displacement part (10) and the rotational part (14) is controlled by a programmable controller (22) and designed to steer the work tool (16) along any path within a work area.
Description
- This application claims benefit of a Norwegian patent application serial number NO 20025798, filed Dec. 3, 2002, which is herein incorporated by reference.
- 1. Field of the Invention
- This invention regards a downhole controlled tool. Specifically, it concerns an arrangement for controlling a tool such as a high pressure water cutter in a manner such that the tool can follow any path, preferably cylindrical, within its working area.
- 2. Description of Related Art
- Wellbore operations have traditionally been carried out by means of relatively heavy tools. As an example, perforation of a casing is known to be carried out through use of conventional drilling equipment. Such equipment is heavy and costly, especially when it has to be procured after the drilling operations have come to an end. Simpler methods have gradually been developed, which are designed to be used e.g. when cutting with a high pressure water cutting material.
- In the following, reference is made, for illustrative purposes, to the control of a high pressure water cutter; however the arrangement of the invention is equally suited for other operations.
- When cutting an opening in a casing wall it is often expedient to simultaneously cut the portion of the pipe wall which is to be cut out, into pieces that after they have come loose, are small enough not to represent a danger to the performance of the tool or adjoining equipment.
- Previously known techniques of controlling cutting tools or other tools in a wellbore do not exhibit the required accuracy and stability for carrying out the above operations with sufficient precision.
- The object of the invention is to remedy the disadvantages of previously known techniques.
- The object is achieved in accordance with the invention by the characteristics given in the appended claims.
- The arrangement of the invention comprises an energy section, a controller, a first anchor and possibly a second anchor. Together, the sections form an elongated tool, the upper end portion of which is typically connected to a pipe string, coiled tubing or a wireline, possibly combined by means of a transition piece. The energy required for operation and control may be stored in the energy section and/or be supplied from the surface. Preferably, the work tool, for example a high pressure water cutter, is connected to the lower end portion of the elongated tool.
- The actuator section comprises an axial displacement part and a rotational part, where the axial displacement part is designed to move the work tool along the wellbore, while the rotational part is designed to rotate the tool about the longitudinal axis of the wellbore. The axial displacement part and the rotational part are both associated with a programmable controller. The programmable controller is designed to steer the work tool along any path within the working area of the cutting tool.
- If the length of the opening to be cut exceeds the length of stroke of the axial displacement part, the elongated tool may be fitted with two anchors to allow the well tool to be indexed accurately in the longitudinal direction of the wellbore.
- The elongated tool is displaced into the wellbore and positioned at the work area. The work tool displaces the cutting tool in the axial direction of the wellbore by means of the axial displacement part and the cutting tool is rotated about the central axis of the wellbore by the rotational part, the cutting tool following the programmed path while high pressure water discharges from the operating nozzle of the cutting tool when the work tool comprises a cutting tool.
- If required, the control of the axial displacement part and the rotational part may be performed manually and remotely by disabling or overriding the control programme.
- The following describes a non-limiting example of a preferred embodiment illustrated in the accompanying drawings, in which:
- FIG. 1 shows an elongated well tool comprising a controlled work tool;
- FIG. 2 is an enlargement of the lower portion of the elongated tool; and
- FIG. 3 shows a simplified schematic circuit diagram for the actuator section.
- In the drawings,
reference number 1 denotes an elongated well tool comprising anenergy section 2, avalve section 4, afirst anchor 6 and asecond anchor 8. A telescoping, rotationally rigidaxial displacement part 10 is arranged between thefirst anchor 6 and thesecond anchor 8. - In this preferred embodiment the
telescopic part 12 of theaxial displacement part 10 is constituted by a piston rod. - A
rotational part 14 is connected to thesecond anchor 8, see FIG. 1. In FIG. 2 therotational part 14 is connected to thetelescopic part 12, thesecond anchor 8 being omitted. - A work tool in the form of a
cutting tool 16 is connected to the opposite, downward facing portion of therotational part 14. - The upper end portion of the
elongated well tool 1 is connected to coiledtubing 18 by means of atransition piece 19. - The
axial displacement part 10 is equipped with aposition transmitter 20 designed to provide information regarding the relative position of thetelescopic part 12 via aline 24 to acontroller 22. Anangle transmitter 26 is connected to therotational part 14 and is designed to provide information regarding the relative angular position of therotational part 14 via aline 28 to thecontroller 22. - The
axial displacement part 10 and therotational part 14 receive working fluid from thevalve section 4 viapipe connections - The servo valves (not shown) of the
valve section 4 receive working fluid from theenergy section 2 viapipe connections 34 and are controlled by thecontroller 22 vialines 36. Thecontroller 22 communicates with corresponding equipment (not shown) on the surface in a known manner. - After the
elongated tool 1 has been positioned in acasing 40 where anopening 42 is to be cut in the pipe wall of thecasing 40, see FIG. 2, the elongated tool is secured to thecasing 40 by thefirst anchor 6 in a manner that is known per se. - The
cutting nozzle 44 of thecutting tool 16 is oriented into the correct position by means of theaxial displacement part 10 and therotational part 14, whereupon thecutting nozzle 44 is steered along a desired path while delivering high pressure cutting water. - The control of the
axial displacement part 10 and therotational part 14 is implemented via thevalve section 4 by means of a control programme in thecontroller 22 and/or from the surface. - Preferably, the material removed is cut into
smaller pieces 46 in order to ensure that the cut-out material does not obstruct further work in thecasing 40. Thepieces 46 are illustrated by broken lines in the as yet not finished opening 42 in FIG. 2. - If the length of the
opening 42 is to exceed the length of stroke of theaxial displacement part 10, thesecond anchor 8 is anchored, whereupon thefirst anchor 6 is released and moved to a new, appropriate position. Thefirst anchor 6 is anchored, whereupon thesecond anchor 8 is released prior to a new section of theopening 42 being cut. - The
rotational part 14 may be disposed in any position between theupper anchor 6 and thecutting tool 16, and may be formed as an integral part of theaxial displacement part 10. - In an alternative embodiment, the
axial displacement part 10 and/or therotational part 14 may be electrically driven.
