Definitions

  • the present invention relates to devices for producing, in association with a drill, a well in a given soil in which it is further provided the installation of a casing to avoid, for example, that the wall of the well is not collapse and that the operations that are planned can be carried out unhindered at the bottom of the well, for example the measurement of the pressure prevailing at a certain depth of the soil or subsoil, the measurement of the porosity of the rocks of this subsoil. soil, hardness, layer composition, etc.
  • devices have been developed to facilitate the casing of the well while drilling it in order to reduce the overall cost of one unit length of a cased well.
  • a device is for example described in the EP-A-1,936,109 .
  • this device is very complex, comprising for example three drive units to ensure only two functions, namely the rotation of the rod in one direction and the rotation of the casing in the other direction.
  • US-2008/164044 which is considered the state of the art closest to the object of claim 1, discloses a device with the features set forth in the preamble of claim 1.
  • the present invention aims to provide a device for producing, in association with a drill, a well in a soil, which overcomes the disadvantages mentioned above, which is a structure more simple and less expensive, and easy to use with easy maintenance.
  • the present invention relates to a device for producing, in association with a drill, a well in a given soil, as defined in the attached generic claim.

But in the applications that are most common with this kind of device for the realization of a well, for example the measurement of certain parameters of a ground or subsoil at depths of the order of some ten meters , or from one to a few hundred meters, such a drilling tool 20 is for example of the type firing pin, auger, such as those known under the name TRICONE, blade tool or the like.
  • the rod 10 is generally constituted by a plurality of rod portions adapted to abut each other, for example by screwing, keying or the like, to form a rod 10 of the desired length, as and when required. progress of digging the well.
  • the casing 30 generally consists of a plurality of tubes that can be removably joined to one another, for example also, as for the stem portions, by screwing, keying or the like.
  • the device further comprises means 60 for rotating the casing 30 about the second axis 31 in a second direction S2 opposite to the first direction S1 of the rotation of the rod, when drilling the well in the soil by means of of the drilling tool 20.
  • the rotations in the directions S1 and S2 can be respectively “right” and “left”, according to the terminology in the field concerned by the invention, or vice versa.
  • the two speeds of rotation respectively of the rod 10 and the casing 30 may be, in absolute value, equal or different, only if they are opposite signs or opposite directions according to the definition of the invention.
  • the means 50 for driving the rod 10 in rotation in a first direction S1 about its axis 11 and the means 60 for driving the casing 30 in rotation in a second direction S2 opposite the first about its axis 31, are constituted by a one and only drive motor 80 comprising an output shaft 82, and two sets of gear gears 51, 61, the two sets 51, 61 being connected to the output shaft 82 and, respectively, to the end proximal 12 of the rod 10 and at the proximal end 32 of the casing 30, the two sets each comprising a chain of gear gears Ch1, Ch2, the chain of one comprising a number N of gear gears, and the chain of the other a number Y of gear gears equal to N + x, N being any integer and x an odd integer.
  • the drive motor 80 is advantageously one of the following motors: pneumatic, hydraulic, fluidic, electric.
  • the chain of gear wheels Ch2 mounted in cooperation with the proximal end 32 of the casing 30 comprises a final pinion 64 and a sleeve 65 integral with this final pinion being fixed thereto by the one of its two ends while being centered on the rod 10.
  • the sleeve 65 is fixed on the final pinion 64, for example by welding, or by a one-piece embodiment of the final pinion 64 and the sleeve 65.
  • the device Dr for the production of a well Pu also comprises dismountable coupling means 90 for connecting the end of the sleeve 65 opposite that which is secured to the final pinion 64, with the proximal end 32 of the casing 30.
  • FIG. 2 An example of these removable coupling means 90 is illustrated on the figure 2 , very schematically including a coupling sleeve 94, a tip 96 fixed on one end of this coupling sleeve 94 and adapted to be fixed on the proximal end 32 of the tubes of the casing 30, for example by screwing if the tubes of the casing are screwed into each other, the other end of the coupling sleeve 94 having latching means 98, for example key, clips or any other appropriate means removable from the field of the art, suitable for cooperate with the free end of the sleeve 65.
  • latching means 98 for example key, clips or any other appropriate means removable from the field of the art, suitable for cooperate with the free end of the sleeve 65.
  • the means 40 for mounting the rod 10 in the casing 30 comprise a mounting housing 42 and means for cooperatively mounting the mounting housing with the proximal ends 12, 32 respectively of the rod 10 and the casing 30, so that these two proximal ends 12, 32 are able to cooperate respectively with the two sets 51, 61 gear pinions.
  • the device further comprises means 70 for applying percussion forces on at least one of the two following elements: proximal end 12 of the rod 10, proximal end 32 of the casing 30, but preferably on the only proximal end 12 of the stem.
  • means 70 for applying percussive forces are, for example but preferably, consist of a hydraulic or pneumatic hammer well known in itself to those skilled in the art and which will not be more fully described here in the single to simplify the present description.
  • the device Dr for producing a well as described above operates and is used as follows:
  • the device Dr When it is necessary to drill a well Pu with tubing, the device Dr is mounted in a manner known per se on the auger Fo, so that the two axes 11, 31 are generally vertical.
  • a first portion of the drill pipe 10 is mounted in a first tube of the casing 30 as described and illustrated in the two figures, the device being generally positioned, at least its rotational head part as defined previously, at the highest level on the drill rig Fo .
  • the drive motor 80 is started.
  • the rod 10 with its drilling tool 20 is then rotated about the axis 11 in the direction S1, the tool 20 beginning to penetrate the soil So.
  • the first tube of the casing is simultaneously rotated about its axis 31, in the direction S2 opposite to the first S1 and begins to penetrate into the ground.
  • the alternative percussion force given by the hammer 72 is applied to the proximal end 12 of the rod 10.
  • the upper part of the device which essentially comprises the motor, the hammer and the casing and which is generally called the "rotation head" goes down along the drill, until its lowest point, that is to say a distance substantially equal to the length of a rod portion and / or a tubing tube, since a rod portion and a casing tube are generally of same length.
  • the coupling means 90 are then disassembled and the proximal end 12 of the first drill stem portion 20 is uncoupled from the rotation means 50 and the housing 42 and then, at the first pair of "tubing stem-tubing portion" already present , added a new couple, after having taken care, obviously, to go up the high part of the device Dr at the highest point of the drill Fo.
  • the device Dr can again be controlled as previously described to continue drilling the well. These Operations are repeated as many times as necessary to reach the desired depth of the well.
