Definitions

  • the present invention relates to a device and method for protecting a measuring instrument (probe) or a specialized tool for intervention in a well, this tool being fixed to the end of a column.
  • the tool or instrument is brought out of its casing, or protective casing, by a movement of this tool or instrument relative to the column and the casing, the latter being fixed relative to the column.
  • the devices according to the prior art move the tool by pumping the liquid inside a hollow column. This has the effect of violently propelling the probe with risks of damage to it, especially if the well is obstructed.
  • the present invention overcomes these drawbacks by providing a retractable protection device for a specialized instrument or tool for intervention in a well, this tool or instrument being fixed to the end of a column.
  • the device according to the invention comprises a casing, or protective casing, of said tool or instrument and is characterized in that the column comprises substantially at its end, and before said tool or instrument, a first guide member and in that the housing comprises a second guide member, these first and second guide members being adapted to cooperate with each other in order to allow the displacement of the housing relative to the tool or instrument.
  • the device according to the present invention may include means for anchoring and locking the casing relative to the assembly formed by said column and said tool or instrument.
  • anchoring means may be adapted to immobilize the casing when the latter protects the tool or instrument, or when it does not protect said tool or instrument.
  • the casing may include centering means in the well.
  • the device according to the present invention may include means for moving the casing relative to the assembly formed by said column and said tool or instrument.
  • the present invention also relates to a method of protection using a protective casing or casing of an instrument or specialized tool for intervention in a well, this tool or instrument being fixed to the end of a column.
  • the method according to the invention is characterized in that the casing is slidably mounted relative to the assembly consisting of the tool or instrument and the column.
  • the assembly consisting of the column and the tool or instrument to remove the latter from its protective casing.
  • the housing remains substantially stationary relative to the well.
  • the reference 1 designates a tool or instrument to be discovered temporarily.
  • This tool which can be a logging probe or any other tool is fixed to a column 2 which can be a drill string, by means of a first guide member 3 which in the case of FIG. 1 is a cylinder .
  • Reference 4 designates a protective casing or envelope.
  • This casing comprises a second guide member 5, such as bearings which can slide on the first guide member 3.
  • FIG. 1 shows the casing 4 in the tool protection position 1.
  • the casing 4 can be held in this position by means of anchoring or locking means 6.
  • these locking means comprise dogs 7 retractable. These dogs can be remotely controlled electromagnetically.
  • the dogs 7 are retracted and the casing 4 is moved so as to uncover the tool to be protected 1 which can then be activated to perform the operations for which it is intended.
  • the tool to be protected and the locking means 6 of the housing on the guide member require an electrical connection with equipment located, for example, on the surface.
  • a male connector 8 fixed inside the column will allow this connection.
  • a connector female 9 fixed to the end of a cable 10 is adapted to cooperate with the male connector 8.
  • the female connector 9 can be lowered into the column by gravity or / and possibly by pumping.
  • the exit and withdrawal of dogs 7 may be controlled by electrical signals transmitted by conductors incorporated in the column.
  • the erasing of the locking means 6 is controlled, for example by electrical signals transmitted by the cable 10 and the connectors 8 and 9. It is then enough to push on the column to bring out the tool 1 of the casing 4, as is the case in FIGS. 2 and 4.
  • the casing 4 will not advance if the forces which retain it and which are due to the forces between the casing and the walls of the weight of the well are sufficient to overcome the driving forces which result from the forces of friction of the casing on the probe and possibly the weight of the housing. Of course, the forces due to the weights of the casing do not intervene in the case where the exit of the probe takes place in a horizontal portion of a well.
  • second anchoring or locking means which may include dogs 11 (fig. 4).
  • unique anchoring or locking means adapted to immobilize the casing in the extended tool position and in the retracted tool position.
  • FIGs 3 and 4 show the case where the protective casing 4 is equipped with centralizers 12 and 13.
  • This centralizer can be of the blade type.
  • a centering device makes it possible to maintain the casing in the center of the well and consequently the tool in the case where it is centered relative to the casing. Furthermore, in certain cases, it is the centralizers which induce a frictional force between the casing and the well 14.
  • Figures 3 and 4 shows a device according to the invention comprising first anchoring or locking means 7 of the housing in protected probe position and second anchoring or locking means 11 of the housing 4 in probe 1 output position (fig. 4).
  • the first locking means comprise dogs 7 which cooperate with an axial support 15 integral with the tool 1 to define a space which will limit the movement of the second guide member 5 which, in this case, will also play the role of axial stop.
  • the dogs of the first and second locking means are included in the space defined by the support means secured to the tool and by the support means secured to the column.
  • Figures 5 and 6 show the casing in the protected probe and probe out position respectively.
  • the device shown in FIGS. 5 and 6 comprises a hollow column 2 and a passage 17 passing through the first guide member 3.
  • the passage 17 opens at one of its ends in the column 2 through an orifice 18 and at its other end in a chamber 19 defined by the second guide member 5 and the support 15 secured to the tool by an orifice 20 .
  • a clearance 21 has been arranged, in order to better allow the pressure forces to cause the displacement of the casing 4 in the position of the probe extended, when the inking or locking means 7 are erased.
  • the casing 4 may include orifices 22 located at the lower part of the casing 4 so that these orifices are uncovered when the probe is out. This will allow the circulation of pumped fluid.
  • the device shown in Figure 6 includes locking or inking means 11 of the housing in the tool out position.
  • control of the various valves necessary for the operation of such a device equivalent to a double-acting cylinder could be carried out by electrical signals or by information transmitted by the fluid circulating in the column, in particular by inserting flow detectors or pressure.
  • the housing then in the protected tool position, then take out the tool and return to the intervention area.
  • Such a mode of operation avoids entering the well with the tool extended and therefore avoids destroying the tool against an obstruction element located in the well such as scree.
