Description

A TOOL AND A METHOD FOR AT LEAST ONE OF THE FIXING, EXPANSION, AND PENETRATION OF A HOLE WALL Background of the Invention The present invention relates to a tool. More specifically, the invention relates to a tool for performing at least one condition of clamping, expanding, and penetrating the wall of a hole. The hole could be defined, for example, by a deposit in the ground or by a pipe. The tool according to the invention is particularly suitable for use when there is a need to expand or penetrate a pipe made of a useful material, i.e., a material that allows for a substantially localized change in shape when subjected to the tool. The tool according to the invention is also suitable for use as a centralizer, for hanging the tool in a recess or restriction, or for use as a slide anchor in a hole. The following description applies to a pipe tool used to expand or penetrate a pipe wall in the oil and gas exploration industry. However, the tool is suitable for use in any industry where there might be a need to expand or penetrate, for example, a pipe wall. In the oil and gas exploration industry, a production well that is no longer reliable for extraction or that requires closure due to any other type of well problem must be plugged to prevent oil and gas reservoir fluids from migrating upward over time and potentially contaminating other reservoirs or aquifers. The process of closing and abandoning a production well is known as plugging and abandonment (P&A). A well is plugged by placing mechanical plugs or cement in the well at specific intervals to prevent fluid flow. The integrity of a plug is typically verified with a pressure test. In many cases, this pressure test reveals that oil or gas is leaking through the plug. A leak, for example, through a plug provided by a cementitious material or other hardenable material, could have several causes. However, the most common causes are typically insufficient filling of the ring between the draw string and the surrounding tubing or wellbore, and insufficient adhesion between the plugging material and the adjacent surfaces defining the ring. Typically, insufficient filling is caused by a draw string that is off-center with respect to the surrounding tubing or wellbore, preventing the material from achieving adequate separation.Typically, insufficient adhesion is due to residual liquids from the well or tank preventing sufficient contact between the material and surrounding surfaces. WO 2007 / 144719 describes an expandable downhole tool that is incorporated into a drill string, such as a bottom ram or stabilizer. The tool can be set between activated and deactivated modes. To activate the tool, a ball or ball assembly can be lowered below the drill string to mechanically trigger the tool. Alternatively, a ball or ball assembly can be lowered below the drill string to engage a seat, causing the tool to activate based on an increase in a pressure differential. The tool can be deactivated by hydraulic pressure. In one mode, the tool is triggered by lowering a deformable actuator below the drill string.After the actuator deforms, passing downwards through a receiving seat, the tool is then allowed to readjust itself automatically in the deactivated mode. EP2616625 describes a drilling tool for drilling casing at the bottom of a borehole, and a work string incorporating this drilling tool. The tool comprises at least one movable cutting block. The cutting block is moved by means of an actuating member, which is actuated by a plurality of pistons located in pressure chambers. US Publication 1897985 describes a regulator for oil wells, the regulator comprising a tube smaller in outside diameter than the well casing, a plurality of slides positioned circumferentially around the tube, a tapered mandrel in sliding clutch with the tube and tapered to force the slides outward against the casing, means in the mandrel for clutching with the tips, and means actuated by the downward travel of the mandrel for releasing the tips. Publications RU 2612392, RU 2302515, and RU 2546695 disclose a first tool part and a second tool part that is axially movable relative to the first tool part. The first tool part comprises a wedge, and the second tool part comprises an influence portion. Operating an expansion tool using a drill string or work string can be disadvantageous in terms of time, cost, and operational control. Similarly, using drill pipe or coiled pipe for any subsequent cementing and washing operations can sometimes be disadvantageous in terms of time, cost, and operational control. Therefore, an industry trend is to perform these operations as offline as possible, meaning without the use of expensive drilling equipment. Any operation that can be performed using a wireline is preferred. However, in a situation where a drill rig or coiled pipe is already set up on site, it can be impractical to run the wireline equipment up and down during a single operation.Therefore, the tool could also be configured to be laid on the drill pipe or coiled pipe, even though laying the tool on the cable is normally preferred. Summary of the Invention There is a need in the industry for a tool that can be configured for wireline operations, or alternatively, coiled pipe or drill pipe operations. There is also a desire for a tool that can be configured to penetrate, wash, and / or cement a ring surrounding, for example, a drill pipe. The invention aims to remedy or reduce at least one of the drawbacks of the prior art, or at least to provide a useful alternative to the prior art. The objective is achieved through features that are specified in the following description and in the claims that follow. The invention is defined by the independent patent claim. The dependent claims define the advantageous embodiments of the invention. Description of the Invention In a first aspect of the invention, a tool is provided for performing at least one condition of clamping, expanding, and penetrating a hole wall, the tool comprising a first tool part and a second axially positioned tool part that can be moved relative to each other, wherein the first tool part comprises a solid wedge, while the second tool part comprises at least one wedge arm; - wherein the first and second tool parts are aligned so that one end of the solid wedge is directed towards one end of at least the wedge arm; - wherein the first tool part also comprises at least an influence portion configured to be radially movable based on contact with at least the wedge arm of the second tool part; and - wherein when the tool is activated and the tool parts are forced against each other, at least the wedge arm is configured to be moved axially along the solid wedge so that it is forced radially outwards and in this manner, pushes at least the influence portion radially outwards to perform at least one condition of clamping, expanding, and penetrating the hole wall. The term influence portion means a portion for clamping, expanding and / or penetrating the hole wall. When the tool is configured to expand and / or penetrate a hole, the hole is made up of a pipe. The wedge arm is wedged between the solid wedge and the influence portion when the tool parts are forced toward each other. Preferably, where at least one end of the wedge arm is shaped as a double wedge. The term double wedge means a wedge comprising two wedge faces, where one face is inclined upwards with respect to a longitudinal axis of the wedge arm, and the other face is inclined downwards with respect to a longitudinal axis of the wedge arm. Thus, in a longitudinal section view, this double wedge could have an arrow-like shape. This has the effect that when the parts of The tools are forced against each other; the face of the double wedge that slides on the solid wedge pushes the wedge arm downward radially about the tool's longitudinal axis. Additionally, the face of the double wedge that supports the influence portion pushes the influence portion radially outward about the tool's longitudinal axis. This achieves a triple radial motion effect while maintaining axial structural integrity in the expanded position. This triple radial expansion effect has the advantage that the tool can be thinner relative to the pipe string receiving it. When the tool is thinner, there are fewer constraints within the pipe string that can be passed through the tool. In a prototype of the tool, the tip of the influence portion, the tip of the solid wedge, and the tip of the double wedge of the wedge arm are placed substantially close to each other on the centerline of the tool. The influence portion could be connected to the first tool part by means of a finger. The finger could be a cantilever finger, i.e., the finger could be cantilevered from the first tool part. In one embodiment, the finger is cantilevered from an end portion of the first tool part comprising the solid wedge. A cantilever finger could be made elastic to allow retraction of the influence portion when the tool parts are axially separated from each other, i.e., when the wedge arm is retracted. In an alternative embodiment, the finger connecting the influence portion to the tool part comprising the solid wedge could be connected by means of a joint, i.e., the finger could be articulated to the first tool part. In one configuration, the tool is set up so that when it is in an inactive position, the finger is positioned in a recess designed to accommodate it. Therefore, the finger is not added to the tool's external dimensions when it is in its passive position. Preferably, when the tool is in an inactive position, the radial extension or protrusion of the influence portion is substantially equal to or less than the radial extension or protrusion of the tool part to which it is connected, i.e., the first tool part. Therefore, the influence portion does not add, or adds only imperceptibly, to an external dimension of the tool when the tool is in its passive position. In an embodiment where the hole is a pipe, and when the tool is in an active position, the influence portion is configured to expand the pipe wall. The term "inactive position" means any position where the influence portion has a radial extension greater than the radial extension of the first tool portion. In this embodiment, the tool could be used to increase the inside diameter of the pipe by radially expanding it. In one embodiment, the tool could be provided with a plurality of fingers with influence portions and corresponding wedge arms mutually separated around a portion of the tool.When the tool is provided with at least three influence portions and wedge arms positioned around the periphery of the tool, the tool could be used to center a first pipe with respect to a hole or a second pipe surrounding the first pipe, or to center and drill a first pipe with respect to a hole or a second pipe surrounding the first pipe. In one embodiment, the influence portion could be configured to expand and perforate a pipe string by applying a local stress or point load that exceeds the breaking strength of the pipe material. In a configuration where the hole is a pipe, the influencing portion could be configured to penetrate the pipe wall. In this configuration, the influencing portion could be provided with a protruding or punching means that penetrates the pipe wall without substantially expanding it. The finger could comprise two separate finger portions that provide space to accommodate or house a portion of the solid wedge of the first tool part when the tool is in an inactive position. This has the effect that the finger portions could accommodate a portion of the solid wedge. In one embodiment, where the tool is configured to grip a hole wall, the influence portion could comprise a toothed clamping face. In one embodiment where the influx portion is configured to penetrate the pipe wall, the influx portion may be provided with an opening in fluid communication with a conduit configured to receive an injection fluid from an injection fluid source. An injection fluid could be, for example, a hardened fluid such as cement or epoxy, or water, chemicals, or a flushing agent. In this manner, the tool according to the invention could be used to inject a fluid into a ring between the outside of the pipe into which the tool has been inserted and a surrounding well or second pipe. For a tool configured for fluid injection, it may be advantageous, though not necessary, to provide a finger having a relatively large cross-sectional area to accommodate a fluid supply channel.Thus, a one-piece finger is preferred to a finger comprising two finger portions as discussed previously. For the purpose of housing this one-piece finger, the solid wedge could include a recess configured to accommodate or accommodate the finger when the tool is in an idle position. In a second aspect of the invention, a method is provided for achieving at least one condition of clamping, expanding, and penetrating a hole wall, the method comprising: - provide a tool in accordance with the first aspect of the invention for use in the method; - connect the tool to a control device configured to operate the tool; - position the tool inside the hole and lower it to a desired location within the hole; - Activate the tool to perform at least one condition of clamping, expansion, and penetration of the hole wall. Once the borehole wall has been influenced by the influence portion, the method could further involve deactivating the tool by bringing it into a radially passive or retracted position and moving it. The tool could then be moved to a new location and activated to influence the borehole wall, or it could be removed from the borehole. When the hole is a pipe in a well, the tool could be provided with an influence portion, i.e., a portion for gripping, expanding and / or penetrating the hole wall, provided with an opening that is in fluid communication with a conduit configured to receive an injection fluid from an injection fluid source, and the method could further comprise injecting the fluid into a defined ring between an outside of the pipe and a hole surrounding the pipe.

Position indications, such as, for example, left and right, outward and inward, refer to the position shown in the figures. Ab / bnn / ζζηζ / Ε / γίΛΐ In the figures, some elements are indicated by the same reference numbers. For clarity, some elements may occasionally appear in the figures without reference numbers. A person skilled in the technique will understand that the figures are only preliminary drawings. The relative proportions of the individual elements could be greatly distorted. In the figures, reference number 1 denotes a pipe tool according to the present invention. Pipe tool 1 comprises two tool parts, a first tool part 10 and a second tool part 30, which, for clarity, are shown individually in Figures Ig and Ih, respectively. As shown in Figure 1g, the first tool part 10 has a first end portion 2 and a second end portion 3. The second end portion 3 comprises a rod 5. The rod 5 is connected to the first end portion 3 by means of the body arms 16. In the operation of the tool 1, the rod 5 serves as a means of transmitting force from an actuator operated from a remote location, such as a drilling rig on the surface. The second tool part 30 shown in Figure 1h comprises the cantilevered wedge arms 32 of a sleeve 34. In the embodiment shown, the wedge arms 32 form part of a split wedge. The wedge arms 32 are deflected to a passive or radially retracted position. In an alternative embodiment (not shown), the wedge arm could be hinged to the sleeve 34 of the second tool part 30. However, a cantilevered wedge arm 32 is preferred since this arm tends to tilt to its radially retracted or passive position when the first tool part 10 and the second part 30 are axially separated from each other. In an embodiment where the cantilevered wedge arm is made of a material that can be separated from this sleeve 34, the material can be selected to achieve a desired deflection effect. In all figures other than Figures Ig and Ih, tool 1 is shown assembled. At least a portion of rod 5 is housed within the second tool part 30, and the body arms 16 of the first tool part 10 are intercepted by the wedge arms 32 of the second tool part 30. The first tool part 10 and the second tool part 30 are positioned so that they can move axially relative to each other. The first part of tool 10 comprises a wedge RWfrnn / zznz / E / YiAi solid 12 pointed towards one end of the wedge arms 32 that are part of the split wedge. An influence portion 14 is connected to the first tool part 10 and radially movable by the wedge arm 32 of the second tool part 30. The wedge arm 32 is positioned so that it is forced radially outward by the solid wedge 12 when the tool parts 10 and 30 are axially moved against each other. By this relative movement of the tool parts 10 and 30, the wedge arm 32 is configured to advance or push the influence portion 14 radially outward against a pipe wall W to expand or penetrate the pipe wall P, as shown, for example, in Figure 3b. In the modalities shown, each influence portion 14 is connected to the first tool part 10 by means of a finger 15 cantilevered from the first portion 2. Figures 1a-2b show an embodiment of tool 1 according to the present invention, wherein tool 1 is in the passive position with the influence portions 14 (four of which are shown in Figure 11) in a radially retracted or passive position. In this passive position, the influence portions 14 have a radial periphery or outer surface that is substantially the same as the peripheral surface of the solid wedge 12 and the peripheral surface of the body arm 16 that connects the first end portion 2 to the second end portion 3 of the first tool part 10. Thus, the influence portions 14 could be considered as housed within a portion of the first tool part 10 when tool 1 is in its passive position. This has the effect that the influence portions 14 will slide through any obstruction or restriction, provided that the first tool part 10 and the second tool part 30 slide through this restriction. In the perspective view shown in Figure 1a, the finger 15 connecting the influence portion 14 to the first tool part 10, as previously mentioned, is cantilevered from the first end portion 2 of the first tool part 10. A cantilever finger 15 could be formed from the same piece of material as the body arm 16, although typically it is machined from a separate piece of material mechanically connected to the first end portion 2. In an alternative embodiment (not shown), the finger 15 could be hinged to the first end portion 2 of the first tool part 10. However, a cantilever finger 15 is preferred since the finger tends to deflect to its passive or radially retracted position when the first tool part 10 and the second part 10 are axially separated from each other.In a modality where the cantilever finger 15 is made of a material that is separate from the body arm material 16, the material can be selected to meet the desired deflection effect. In one embodiment (not shown) finger 15 and wedge arms 32 are configured with guide means, such as, for example, wedges, to provide mechanical radial retraction of finger 15 and wedge arm 32 when the first tool part 10 and the second tool part 30 are axially separated from each other. In the longitudinal cross-section views in Figures 1c and 2b, an end portion of the wedge arms 32 (two are shown) is shown being held through a tip of the solid wedge 12, and the tip of each wedge arm 32 is inserted between the solid wedge 12 and a portion of the influence portion 14. In this way, in this initial position, the wedge arms 32 are correctly positioned with respect to the solid wedge 12 and the influence portion 14 to facilitate the movement of tool 1 into its active position as shown, for example, in Figure 3a. In the off-center longitudinal cross-sectional view shown in Figures 1d and 2b, and in the cross-sectional view shown in Figure 11, a modality is shown in which finger 15, which carries the influence portion 14, comprises two separate parallel portions of finger 15', 15. A detail of the finger portions 15' and 15 is shown in Figure 3d. One purpose of this finger arrangement is to prevent finger 15 from adding to the tool diameter when tool 1 is in its retracted or passive position. This is achieved by providing the recesses between the body arm 16 and the solid wedge 12 configured to receive finger portions 15' and 15. In this way, finger 15 is positioned on both sides of a portion of the solid wedge 12, as best seen in Figure 11. Another purpose of this finger arrangement is to provide a common solid wedge capable of obtaining reaction forces from the opposing fingers 15. In Figure 3a, fingers 15 and influence portions 14 have been pushed radially outward by forcing the first tool part 10 and the second tool part 30, which has been pushed axially toward each other. This is achieved by pushing rod 5, and thus the entire first tool part 10, relative to the second tool part 30. This relative movement between the first tool part 10 and the second tool part 30 is activated by an external actuator configured to retain the second tool part 30 while simultaneously engaging and moving rod 5 of the first tool part 10. In the embodiment shown in Figure 3a, the first tool part 10 has been moved to the right relative to the second tool part 30. It should be noted that tool 1 is adapted to the commercially available external actuator.This actuator is shown in Figures 8a and 8b, while another type of actuator is shown in Figure 9. Figures 3b and 3c show tool 1 once the influence portions 14 have penetrated a wall W of a pipe P. The influence portions 14 in Figures 1a-1d, 1f-3d are shown with an outward facing surface that is relatively small and flat. Typically, this configuration of the influence portion 14 could be used when the tool 1 is for expanding and penetrating a portion of the pipe wall W. However, if the purpose of the influence portion 14 is only to expand the pipe wall, for example, to center a pipe P inside an outer pipe or inside a hole (not shown), the outward facing surface of the influence portion 14 would be made larger, and / or the number of influence portions 14 and the proper fingers 15, and the wedge arms 32, would be increased to avoid very high local stresses that exceed the breaking strength of the pipe material. Apparatus 1 could be configured with fewer than four influence portions 14 shown, i.e., one, two or three, or more than four influence portions 14. Figures 4a-7b show an alternative embodiment of tool 1 according to the present invention, wherein tool 1 is configured to penetrate a wall W of a pipe P and inject a fluid through the wall of pipe P by means of the influence portion 14. The fluid could be, for example, a cleaning fluid for cleaning surfaces in a defined ring on the outside of pipe P and another pipe or well surrounding pipe P, or it could be a hardenable plugging material for plugging the ring. In this alternative embodiment, the function of the solid wedge 12 and the wedge arm 32 is in principle the same as for the tool shown in Figures 1a-3c. However, in the alternative embodiment, only two fingers 15 are shown, and thus only two influence portions 14. Although only two fingers 15 and influence portions 14 are shown in Figures 4a-7b, it should be noted that Tool 1 could alternatively be provided with more than two fingers 15 and influence portions 14, or only one influence portion 14 configured to inject a fluid as described above. In yet another embodiment, there could be a combination of at least one influence portion for injecting a fluid and at least one influence portion 14 of the type shown in Figures 1a-1d and 1f-3d. Each portion of influence 14 shown in the Figures 4a-7b comprise a protrusion in the shape of a lug or knob. Each knob 14 (and thus each influence portion) is provided with an opening 140 or channel that is in fluid communication with a conduit 142 configured to receive an injection fluid from an injection fluid source. As shown in Figures 4d, 5a and 6c, each conduit 142 extends into finger 15 of the opening 140 in knob 14, to a distribution reservoir 144. As shown in Figures 4f and 6e, the distribution reservoir 144 is in fluid communication with a fluid supply channel 146 that extends through the body arm 16 (see Figures 4g-4i and 6f-6h), providing the axial connection between the first end portion 2 and the second end portion 3 of the first tool part 10. The fluid supply channel 146 is configured to receive fluid from a pressurized fluid source (not shown) that could be located at the surface, such as a surface drilling rig (not shown). Typically, surface fluid is supplied to the tool 1 via coiled tubing or drill pipe.As an alternative to supplying the fluid from the surface, the fluid could be supplied from a fluid reservoir at the bottom of the borehole, such as a reservoir (not shown) connected to tool 1, and a pumping system controlled from the surface. A downhole fluid supply system comprising such a reservoir and pump is commercially available. In Figures 4a-5b, tool 1 is in its passive or retracted position. In Figures 6a-7b, tool 1 is in its active or expanded position. Figures 6b-6d, 6f, and 7a-7b show the influence portion or knob 14 penetrating a wall W of a pipe P. In the configuration shown, knob 14 provides a sufficient seal against wall W. In the embodiment shown in Figures 4a-7b, where the influence portion or knob 14 is configured to communicate a fluid, each finger 15 is a one-piece finger rather than a finger comprising finger portions 15', 15 as discussed previously. Due to its cross-sectional area, a one-piece finger 15 is better suited to accommodate the fluid conduit 142 than a finger comprising two finger portions 15', 15 with a smaller cross-sectional area. For the purpose of housing this one-piece finger 15, the solid wedge 12 is configured with recesses 13 arranged to accommodate the fingers 15 when the tool 1 is in an idle position, as shown in Figures 4a-5c. The recesses 13 in the solid wedge 12 are best seen in Figures 4f, 6f, and 6g. A width of the recess 13 is longer than a width of the solid wedge 12 to allow finger 15 to reside within the recess 13 when tool 1 is in its passive position, but smaller than a width of the wedge arm 32 to allow wedge arm 32 to be pushed radially outward by the solid wedge when tool parts 10, 30 are forced against each other. Figures 8a and 8b show an embodiment of tool 1 in which the second tool part 30 houses a rod drive means 6. The rod drive means 6 (see Figure 8b) comprises a flange 7 having an outer portion that resides in a corresponding recess in an inner wall of the sleeve 34 of the second tool part 30. In this way, the rod drive means 6 is configured for rotation, although axial movement with respect to the sleeve 34 is prevented. A portion of the rod drive means 6 is in the threaded clutch with a threaded hole 8 in a portion of the rod 5, and the rod 5 can move axially, although rotation with respect to the sleeve 34 is prevented by means of the splines 38, as shown in Figure 8b. An end portion of the sleeve 34 is provided with a neck 35 fixed thereto.The neck 35, which is fixed to the sleeve 34, is designed for connection with a manipulator tool (not shown) configured to engage with a rotating end portion 36 of the drive means 6. Thus, when the manipulator tool is engaged to rotate the rod drive means 6, the rod 5 will be moved in an axial direction. The second tool portion 30 connected to the manipulator tool is held stationary, while the first tool portion 10 is moved axially relative to the second tool portion 30. The direction of the axial movement is controlled by controlling the rotational direction of the manipulator tool. Examples of manipulator tools suitable for controlling the tool 1 according to the present invention are described in EP 3049610 and US 10,364,639. One advantage of the rod drive means 6, operable by a rotary handling tool, is that an operator can obtain accurate, real-time feedback on the radial position of the influence portion 14. The thread pitch of the threaded connection between the rod drive means 6 and the threaded hole 8 of the rod 5, and the pitch angles of the wedges 12 and 32, configured to rest against each other and the influence portion 14, are known for each tool. By providing the handling tool and / or the rod drive means 6 with a counting device configured to count the number of revolutions, the position of the influence portions 14 can typically be calculated by a computer receiving input data from the counter, as will be appreciated by a person skilled in the art. In an alternative embodiment shown in Figure 9, the axial movement of the rod 5 could be provided by means of a controllable hydraulic piston 40 positioned as an extension of the sleeve 34. The hydraulic piston 40 comprises a plurality of annular piston chambers 42 that are in fluid communication with an annular fluid communication conduit 44. The fluid communication conduit 44, in one embodiment, could be in fluid communication with a fluid line extending to a remote location, such as, for example, a drilling rig. Alternatively, the fluid conduit could be in fluid communication with a pump and reservoir system positioned close to the tool 1. In yet another embodiment (not shown) the axial movement of rod 5 could be provided, for example, by means of the so-called drill pipe stroke, or coiled pipe stroke (not shown). Preferably, the tool 1 shown in Figures 1a-3d is cable-operated. Alternatively, it may be operated by means of drill pipe or coiled pipe as mentioned in the preceding paragraph, or by means of a handling tool as described in EP 3049610, wherein the handling tool is connected to an end portion of coiled pipe or drill pipe. Tool 1, shown in Figures 4a-7b, could be operated by wireline, drill pipe, or coiled pipe to penetrate the pipe wall W. If Tool 1 is operationally connected, for example, to a container for injection fluid and a pump to flow the fluid from the container to Tool 1, Tool 1 can be operated by wireline only. However, if a large volume of injection fluid is required for a specific operation, the fluid must be supplied from the surface. In this situation, at least the injection stage of the fluid is delivered by coiled pipe or drill pipe. Thus, in this situation, Tool 1 could first be operated by wireline to penetrate the pipe wall W, whereupon the wireline is retrieved and replaced with coiled pipe or drill pipe.Alternatively, tool 1 is operated on the coiled pipe or drill pipe to penetrate the pipe wall and inject the fluid. Preferably, the tool 1 shown in Figures 8a and 8b is operated on cable. However, it could alternatively be operated on coiled pipe or drill pipe, where the coiled pipe is operationally connected to an electric or hydraulic rotary motor configured to engage with the neck 35 and the rotating end portion 36 of the drive means 6. Tool 1, shown in Figure 9, can be operated on wireline, coiled pipe, or drill pipe. If Tool 1 is operationally connected, for example, to a reservoir for holding hydraulic fluid to operate hydraulic piston 40, and a pump to flow fluid to and from hydraulic piston 40, Tool 1 can be operated on wireline only. Alternatively, Tool 1 can be operated on coiled pipe or drill pipe configured to control hydraulic piston 40. It should be noted that a hydraulic piston could be used to operate a tool provided with an influence portion 14 as shown in Figures 4a-7b, configured to inject a fluid into a ring on an outside of pipe P. This tool could be operated in the same way as discussed above with respect to Figures 4a-7b. Regardless of the various configurations discussed above, with respect to a longitudinal axis of tool 1, the tilt angle of the wedge portions of the solid wedge 12 and the wedge arm 35 is customized for specific needs. For example, if it is desired to provide a tool 1 where the axial movement of the rod 5 is small, and thus the relative axial movement between the first tool portion 10 and the second tool portion 30 is small, the angle of inclination with respect to a longitudinal axis of tool 1 could be, for example, up to 60°. This angle of inclination requires a large force to expand or penetrate a wall W of a pipe P. However, if the purpose of the influence portions 14 is to center tool 1 within the pipe P, and / or to hang tool 1 in a recess or restriction, there is no need for a large force. A large angle of inclination of the wedge portions might be desirable in this application of tool 1. If the primary purpose of tool 1 is to expand or penetrate a wall W of a pipe P, as shown in the figures, it is preferable that the inclination angle of the wedge portions of the solid wedge 12 and the wedge arm 32 be relatively small. In one embodiment, the inclination angle with respect to a longitudinal axis of tool 1 could be as small as, for example, 5–6°. A consequence of this embodiment is that the axial movement of the rod 5 is large, and thus the relative axial movement between the first tool portion 10 and the second tool portion 30 is also large. This large movement provides resistance with respect to the rotational or axial forces applied to the rod 5. If desired, complementary tilt angles can be provided for the solid wedge portion 12 and a face of the wedge arm 32 configured to support each other. However, the tilt angle of the face of the double wedge configured to support the wedge portion of the solid wedge 12 could be different from that of the face of the double wedge configured to push the influence portion 14 radially outward. Preferably, when the finger 15 with the influence portion 14 is near its outermost radial position, the face of the portion of the wedge arm 32 configured to push the influence portion 14 radially outward is parallel to the bearing face portion of the finger 15. The reason for this is to at least reduce the bending motion in the end portion of the finger 15 that carries the influence portion 14 when the influence portion 14 supports the inner surface of pipe P. From the description herein, it shall be understood that the tool 1 according to the invention could have a large operating range such that the radial extension of the influence portion 14 could be large with respect to the radius of the tool 1. Furthermore, the tool 1 is reliable because in principle it comprises only two parts that can move relative to each other in the axial direction, and because the activation and deactivation of the influence portion(s) 14 is the result of wedges sliding relative to each other. It should be noted that the embodiments mentioned above illustrate rather than limit the invention, and that persons skilled in the art will be able to devise many alternative embodiments without departing from the scope of the appended claims. In the claims, any reference numbers placed in parentheses shall not be construed as limiting the claim. The use of the verb "comprises" and its configurations does not exclude the presence of elements or steps other than those indicated in a claim. The article "a" preceding an element does not exclude the presence of a plurality of such elements. The mere fact that certain measures are indicated in the mutually different dependent claims does not indicate that a combination of these measures cannot be used to an advantage.
