Definitions

  • This invention relates to a downhole tool detection means.
  • it relates to a means for determining when a tool in a well is near the surface valve.
  • the tool is lowered through the valve and down into the well.
  • the progress of the tool is monitored via a depth indicator. Due to the high value of production from an individual well, it is important to perform all workovers quickly. As a well may typically be 30,000 feet deep it is clear that it is desirable to lower and retrieve tools at high velocities.
  • a common approach to depth indication during wireline operations involves the use of a calibrated tangential wheel or sheave at the surface. This allows measurement of the length of wire in the well and therefore the depth of the tool.
  • this technique is not sufficiently accurate.
  • the circumference of the wheel may vary due to mud or ice build-up; the wheel may slip relative to the wire; the wire will stretch by an unpredictable amount from the weight of the tool and from the unpredictable stresses when the tool collides with or snags on the edge of the well; furthermore, the dimensions of the wheel and the wire both vary with temperature.
  • Even proportionately small errors lead to substantial uncertainty in the location of the tool. As a result of this uncertainty, great care must be taken not to overrun the tool or else costly accidents occur.
  • downhole tool retrieval detection apparatus comprising means on a surface assembly for detecting the presence of a tool assembly within the surface assembly.
  • the downhole tool retrieval detection means comprises a sensing means which is positioned on the well riser, near the surface valve.
  • the sensing means may be mounted on the outside of the well riser.
  • the sensing means comprises a sensor bracelet which is adapted to removably encircle and grip the well riser.
  • the downhole tool may be labelled by a tool indicator means characterized in some way which can be detected by the sensing means.
  • the indicator means may be adapted to be removably attached to a tool.
  • the indicator means may be adapted to be removably incorporated into a toolstring.
  • the tool indicator means may be incorporated into a tool.
  • the tool indicator means may have distinguishing electromagnetic characteristics and the sensing means be adapted to recognise these characteristics.
  • the tool indicator means may contain a magnet .
  • the tool indicator means may contain a plurality of magnets.
  • the sensing means may be adapted to detect the resulting magnetic field when the tool indicator means passes the sensing means.
  • the sensing means may instead detect the changing magnetic field when the tool indicator means passes the sensor.
  • Figure 1 shows a cross-section through the indicator means and the components to which it is attached
  • Figure 2 shows a well riser and surface valve fitted with a sensor bracelet
  • Figure 3 shows a cross-section through the riser and sensor bracelet along the line A-A of Fig 2;
  • Figure 4 shows a cross-section through the part of the system case where components are stored
  • Figure 5 shows the top of the system case where various indicators are present
  • Figure 6a shows a perspective view of a complete assembly incorporating downhole tool detection apparatus
  • Figure 6b is a perspective view to an enlarged scale of part of the apparatus of Figure 6a.
  • This example embodiment is based on a wireline operation but would apply exactly the same for slickline, electricline and coiled tubing operations.
  • All components of the downhole tool detection means are initially packed in a portable system case which contains both the controls for operation of the device and all other components which are required.
  • an indicator sub 1 On arrival at the site an indicator sub 1 , as shown in Figure 1 , is removed from the system case and removably installed between the rope socket 2 and wireline tool 3 during wireline rig up.
  • the indicator sub has an appropriate adapter 4, enabling it to be removably attached to a wireline tool via a quick latch 5.
  • an adapter 6 and latch 7 As is common practice in the wireline industry, the indicator sub and standard wireline tools incorporate a fishing neck profile 8.
  • the indicator sub contains one or more permanent magnets 9 and is constructed from a material which is either non- magnetic or, if a magnetic material is used, is isolated from the permanent magnet (s).
  • Figure 2 shows a well riser 10 where the wellhead 11 joins the wellhead crossover 12 and wellhead adapter 13.
  • a wireline surface valve 14 is shown in this example.
  • a sensor bracelet 20 is also removed from the case and installed around the neck of the wellhead adapter. Cable 15 is pulled from a reel in the sensor case, safely routed to the wellhead and then attached to the sensor bracelet .
  • FIG. 3 shows a cross section through the wellhead adapter and sensor bracelet 20 along plane A-A.
  • Electromagnetic sensor 21 is adapted to respond to the magnetic field due to the magnet (s) 9 of indicator sub 1 when they pass the sensor. It is incorporated into one or more sensor carrier (s) 22 which is manufactured from stainless steel and has slots through which strap 23 is passed.
  • the sensor bracelet may well incorporate several sensor carriers and sensors, equally spaced around the circumference of the wellhead adapter.
  • the base of the sensor carrier (s), where they sit on the neck of the wellhead adapter, are shaped in such a way as to sit firmly on various diameters of wellhead adapter.
  • Strap 23 is manufactured from flexible strip material such as stainless steel or kevlar. It incorporates a clasp and tightening mechanism which allows the sensor bracelet to be removably secured in position.
  • Figure 4 shows the system case 30 and figure 5 details an indicator panel 31 which is incorporated into the top of the case.
  • the case is constructed of a robust, impact resistant but light-weight material suitable for transportation to offshore working locations and is adapted for rough handling.
  • the case contains customised shaped galleries for storing the indicator sub 32 and the sensor bracelet 33. All loose components are stored within such galleries where they can be firmly secured and strapped in place to avoid the possibility of movement during transport. All equipment which is permanently installed within the case is secured with soft but resilient rubber mounts in such a way as to avoid impact damage. Any necessary hand tools are supplied and stored within the system case and are constructed from chrome vanadium steel.
  • the cable to attach the case to the sensor bracelet is stored on a reel 34.
  • This cable reel has winding handles and rotates on a spindle which incorporates an electrical slip ring so that the cable can be pulled off the reel and electrical continuity will be maintained.
  • the case incorporates an EXD rated battery 35 and a battery charger 36. All electrical and electronic components are EXD rated due to the potentially explosive atmosphere around the wellhead.
  • this device may readily be adapted to automatically stop or slow down the tool lifting gear.
  • This invention it is possible to accurately and reliably determine when a tool is close to the surface valve, without having to rely on the insufficiently accurate depth indicators currently available.
  • This invention will therefore reduce accidents in which retrieved tools are overrun and hit the surface valve, the serious consequences of which were described above. This will not only prevent expensive accidents but may allow tools to be raised faster, reducing the time taken for interventions and so saving money.
  • sensing means may be attached to the outside of the well riser and therefore added or removed quickly and conveniently.
  • the sensing means might also be incorporated in the wellhead adapter itself or another component of the riser.
  • the only significant difference on this embodiment is the addition of a remote visual indicator box 41 which is located in the operators cabin 42.
  • the visual indicator box 41 carried two LED lights. A green light indicates system operational and a red light indicates the alarm activated. The lights are mounted so as to be in the operators line of vision to his other controls and thus avoids the need to glance away to look at the main indicator.
  • the system positively indicates the location of slickline, electricline and coiled tubing tools as they enter and exit the well. It allows operators to retrieve tools into the surface equipment in a controlled manned without having to compensate for depth counter slippage or line/pipe stretch.
