referring first to fig1 there is shown a side cross - sectional view of one wrap of coiled tubing 1 , with a conduit 2 , lying on the inside wall 3 of the coiled tubing . a dotted line 4 shows the diameter center line of the coiled tubing i while a second dotted line 5 shows the diameter center line of the conduit 2 . it will be appreciated that because they have different center line diameters , their lengths per wrap will be slightly different with the coiled tubing being slightly longer . multiplying this difference in length by the total number of wraps enables the difference in overall length to be determined , which can be in excess of 100 ft ( 30 m ). it is this problem which this invention overcomes . referring now to fig2 and 3 , there is shown a method and apparatus to make the conduit 2 wavey , for a straight line length , so that , when it is installed inside the coiled tubing 1 , its length produces a longer length of conduit which will be equal to or of a greater length than the coiled tubing . two methods of achieving this wavey profile are shown . the first is a curved sleeve 6 which fits over a conventional braided wireline 7 and forces the braided wireline to make the wavey shape shown . the distance these sleeves are positioned along the braided wireline determines whether a wavey or a not so wavey braided wireline is produced . in the case of fig3 the conduit could be a hydraulic tube 8 which has been mechanically shaped into the wavey form by rollers 9 and 10 . again the severity of the wave can be chosen to assume any desired frequency . referring now to fig4 to 8 , and fig9 a , 9b and 9c several examples of the conduit function are shown ; viz , an electrical signal via a coaxial cable 11 , an electrical signal / electrical power via a multi - conductor cable 12 , a fiber optics data transmission 13 , a hydraulic conduit 14 or a combination of any of the above in a multi - conductor conduit 15 . in this last example two multi - conductor conduit comprises two hydraulic lines 16 , an electrical line 17 and a fiber optic line 18 . the signal line inside the conduit could also follow a wavey profile , which could be important if the signal line is fiber optic . with reference to fig1 a and 10b , there is shown an anchoring apparatus 20 which is firmly attached to the conduit 21 inside the coiled tubing 22 . the apparatus 20 has a plurality of arms 23 which are in an extended disposition and contact the inner surface 24 of the coiled tubing 22 , anchoring the conduit 21 to the coiled tubing . this makes use of the coiled tubing 22 to carry the weight of the conduit 21 until the next anchoring apparatus 20 , some distance further along the coiled tubing . it will be appreciated that because the conduit 21 does not have to support its entire length when hung vertically in an oil well , its dimensions and weight may be significantly reduced . it will also be appreciated that because the conduit 21 is anchored to the coiled tubing 22 , no movement of the conduit is possible and the conduit remains in the same position regardless of pump rate and gravity effect . this prevents any &# 34 ; bird nesting &# 34 ; or bunching at the extreme end of the coiled tube string which is common with existing wireline installation and which causes cables to be pulled away from an electrical socket at the surface , which may cause the cable to crimp , resulting in a short circuit and disable the cable . in addition fiber optics may also be exploited , as the conduit is anchored to the coiled tubing , and it has a built - in slack due to its wavey form , both in the fiber optic cable inside its conduit , and in addition to the conduit itself having a wavey form , so that the fiber optic cable is not subjected to any stretching whatsoever . fig1 to 16 show two embodiments of the anchoring apparatus 20 , which will now be explained in more detail . in the first embodiment ( fig1 ), there is shown a plurality of sprung fingers 30 , either attached to a central sleeve 31 or machined out of a single tube with the fingers formed to the necessary shape before heat treating them to impart a springy characteristic . the central sleeve 31 is attached to the conduit 21 by adhesive or by some mechanical means , e . g . a screw ( not shown ). on the ends of the sprung fingers 30 , teeth 32 have been provided which anchor the apparatus to the internal surface 24 of the coiled tubing , and resist movement in both directions . so that the conduit 21 may be installed inside the coiled tubing 22 the fingers 30 must be retained close to the conduit surface 33 , which is achieved by using a wrapping material 34 . this may be made from any material which can be removed once the conduit 21 has been installed inside the coiled tubing 22 . the conduit 21 might be installed at the time of manufacture , or installed some time after manufacture . it will be appreciated that if it is installed some time after manufacture it will have to withstand the effects of friction , because the conduit 21 might have to be installed by pumping it through the coiled tubing 22 which could be many thousands of feet long . the wrapping material 34 shown in this example is magnesium wire , which is strong and resists wear and tear as the conduit 21 is pushed into the coiled tubing 22 . once the conduit 21 is in position it is then necessary to remove the magnesium wire . this is achieved by pumping a volume of acetic acid into the coiled tubing 22 and displacing it throughout its entire length . as the acid passes the magnesium wire there is a very rapid chemical reaction which causes the magnesium wire to dissolve rapidly . once it has dissolved the fingers 30 deploy under a spring bias force and move out to a point of equilibrium , where they contact and exert force against the inner surface of the coiled tubing 22 , thereby providing the teeth 32 with some grip and resistance to be pulled along the inside of the coiled tubing 22 in either position . in the second embodiment of an anchoring apparatus , illustrated in fig1 to 16 , there is a tubular member 35 manufactured from titanium which is attached to the conduit 21 as in the embodiment above . sprung members 36 again made from titanium are retained to the anchoring apparatus by a titanium plate 37 ( see fig1 ) which only covers the tip edges 40 of the sprung members 36 . at the end of each sprung member is an edge 38 which when deployed locates in a ratchet groove 39 in the tubular member 35 , so once deployed and subjected to tension again in either direction , the anchor pad 41 is forced harder and harder against the inside wall of the coiled tubing 22 and like all ratchet mechanisms it becomes tighter , locking itself against the coiled tubing wall , becoming a more effective anchor . to keep the sprung members 36 in the retained position , again magnesium is used in this embodiment as small blocks 42 , which keep the sprung members 36 fully extended as the block is trapped between the ratchet surface 39 of the tubular member 35 , the cover plate 37 , the back part of the tip edge 40 and the pillar 43 of the tubular member 35 . titanium has been used in this embodiment for all the parts of the anchoring system , so that if it is required to remove the conduit from inside the coil tubing , it would be possible to destroy the anchoring system by pumping a volume of hydrofluoric acid through the coil tubing . as it is well known that titanium has no resistance to corrosion when exposed to hydrofluoric acid , it provides the possibility of salvaging expensive or special conduits from an old or damaged coil tubing reel . with reference to fig1 , fig1 shows a wavey conduit 21 lying on the lower inner surface 50 of the coiled tubing 22 and bonded at 44 to the coiled tubing along virtually its entire length . this is achieved either at the time of manufacture of the coiled tubing 22 , exploiting the heating treating process necessary to stress relief the coil tubing weld line 45 to also cure the bonding agent 44 or alternatively , the bonding agent 44 could be a layer on the outer surface of the conduit and once all the conduit has been inserted into the coiled tubing can be either exposing the adhesive layer to either a ketone solvent or by exposing the coiled tubing to a controlled heat source in excess of 120 ° c . an industrial adhesive available which could perform this function is a 3m product called scotchgrip 847 , which in addition retains some elastomeric properties while never being reactive again . fig1 to 20 show a further embodiment of an anchor 124 according to the invention . the anchor 124 comprises a conical sheaf support 125 which is attached to and surrounds the perimeter of the conduit 121 . the anchor 124 also includes a gripping part 127 , which comprises circumferentially orientated arms 128 at the end of which are located grips 129 which grip the internal bore of the tube when in the active state as shown in fig2 . the anchor 124 can be activated from the inactive state as shown in fig1 and 19 to the active state as shown in fig2 and 21 by any of the means already described . in this embodiment the grips 129 are oriented so that they act to prevent movement of the conduit from left to right relative to the tube . thus when the anchors 124 are activated it is still possible to move the conduit from right to left but is not possible to move the conduit from left to right . this is useful when installing the conduit . referring now to fig2 and 23 , a novel method is shown for installing a conduit 201 according to the invention in a tube 202 . as shown in fig2 the tube 202 is typically a coiled tube which is conveniently coiled on a drum 203 from which the tube 202 can be readily deployed down a well . the installing apparatus 210 is fitted to the end of the tube 202 . the installing apparatus comprises a pressure chamber 211 in which a pulling mechanism 212 is located . the conduit 201 is threaded into the installing apparatus 210 through a seal 213 by the pulling apparatus 212 and finally into the tube 202 . any suitable pulling mechanism can be used comprising conically arranged grippers . such pulling of the conduit to install it inside the tube 201 is much more effective and less damaging to the conduit than compression of the conduit . the pulling mechanism 212 also preferably comprises cammed pulleys acting on the conduit which serve to induce a wavey profile in the conduit which creates the greater length of the conduit than the tube 202 as discussed previously . pressurized fluid is then introduced into the pressure chamber by means of an inlet valve 214 . the pressurized fluid is preferably water including a friction reducing agent such as long chain polymers such as polyacrylamides . the pulling mechanism 212 pulls the conduit through the seal 213 . a high sealing force is required to achieve the seal 213 and this has to be overcome as more conduit is introduced into the pressure chamber 211 . once the conduit is in the pressure chamber the flow of fluid acts on the conduit dragging it further into the tube 202 . the combination of the pulling tool and the flow rate of the fluid acts to force the conduit 201 down the tube 202 . effective installation is achieved by pulsing the pressure and the pulling on the conduit at the same time . very short installation times have been achieved with this method .
