The entering and existing positions are defined such that an end (52) of the pin is turned towards an inner wall (31) of a cylindrical hollow tube i.e. lantern tube (20), emerged out from the housing and penetrated into a groove (30) under action of the elastic force when the pin arrives opposite to the groove until knocking the pin against a portion of an annular surface (35).

Description

La présente invention concerne les systèmes pour positionner un corps dans un tube creux cylindrique défini selon un axe longitudinal, qui trouvent une application particulièrement avantageuse dans le domaine des forages dans des terrains pour la mesure de certains paramètres de ces terrains.The present invention relates to systems for positioning a body in a cylindrical hollow tube defined along a longitudinal axis, which find a particularly advantageous application in the field of drilling in land for the measurement of certain parameters of these lands.

Il est connu des systèmes pour positionner un corps dans un tube creux cylindrique, par exemple dans le domaine des tubages pétroliers, mais ces systèmes sont très complexes quant à leur structure, difficiles à utiliser et surtout très onéreux.Systems are known for positioning a body in a cylindrical hollow tube, for example in the field of oil casings, but these systems are very complex in structure, difficult to use and above all very expensive.

Un tel système est notamment connu par le Brevet US N° 3 088 521 . Ce système comporte des premiers moyens constitués par une gorge 16 définie sur une surface en forme de "tonneau" avec deux surfaces haute et basse divergentes 17, 18 qui constituent des moyens pour obtenir la transformation d'une première force selon une direction donnée en une seconde force perpendiculaire à la première, et un ergot 43 apte à coopérer avec la gorge 16, ces premiers moyens permettant de positionner le corps par rapport au tube, mais uniquement temporairement et sans certitude, sans obtenir une position précise, et surtout certaine et définitive, du corps par rapport au tube. Le système comporte en outre des moyens pour continuer à faire descendre le corps dans le tube au-delà de la gorge 16, l'ergot passant dans la gorge 16 et la dépassant complètement, jusqu'à la position définitive donnée par deux surfaces complémentaires 26, 27 qui viennent buter l'une contre l'autre.Such a system is in particular known by the patent U.S. Patent No. 3,088,521 . This system comprises first means constituted by a groove 16 defined on a "barrel" shaped surface with two diverging high and low surfaces 17, 18 which constitute means for obtaining the transformation of a first force in a given direction into a second force perpendicular to the first, and a lug 43 adapted to cooperate with the groove 16, these first means for positioning the body relative to the tube, but only temporarily and without certainty, without obtaining a precise position, and especially certain and definitive , of the body relative to the tube. The system further comprises means for continuing to lower the body into the tube beyond the groove 16, the lug passing through the groove 16 and completely beyond it, to the final position given by two complementary surfaces 26 , 27 who come up against each other.

Aussi, la présente invention a-t-elle pour but de réaliser un système pour positionner un corps comme une sonde ou analogue dans un tube creux cylindrique, qui soit d'une structure simple, facile à réaliser et à utiliser, et qui pallie les inconvénients des systèmes similaires de l'art antérieur.Also, the object of the present invention is to provide a system for positioning a body such as a probe or the like in a cylindrical hollow tube, which is of a simple structure, easy to make and use, and which overcomes the disadvantages of similar systems of the prior art.

Plus précisément, la présente invention a pour objet un système pour positionner un corps dans un tube creux cylindrique défini selon un axe longitudinal, ledit positionnement devant être effectué à partir de l'extrémité proximale du tube, comportant au moins les caractéristiques selon la première revendication annexée.More specifically, the present invention relates to a system for positioning a body in a cylindrical hollow tube defined along a longitudinal axis, said positioning to be made from the end proximal of the tube, comprising at least the features according to the first appended claim.

  • Les figures 1 et 2 représentent un schéma de principe du système selon l'invention pour positionner un corps dans un tube creux cylindrique, la figure 1 étant une demi-coupe longitudinale référencée I sur la figure 2, la figure 2 étant une coupe transversale référencée II sur la figure 1, et
  • La figure 3 est une vue en coupe longitudinale d'un mode de réalisation préférentiel du système selon l'invention en accord avec la représentation selon les figures 1 et 2, pour positionner un corps dans un tube creux cylindrique, dans une application à la mesure d'un paramètre donné en un endroit déterminé d'un sol dans lequel est effectué un forage.
Other characteristics and advantages of the invention will appear in the course of the following description given with reference to the accompanying drawings for illustrative but not limiting purposes, in which:
  • The Figures 1 and 2 represent a schematic diagram of the system according to the invention for positioning a body in a cylindrical hollow tube, the figure 1 being a longitudinal half-section referenced I on the figure 2 , the figure 2 being a cross-section referenced II on the figure 1 , and
  • The figure 3 is a longitudinal sectional view of a preferred embodiment of the system according to the invention in accordance with the representation according to the Figures 1 and 2 , for positioning a body in a cylindrical hollow tube, in an application to the measurement of a given parameter in a given location of a soil in which a drilling is performed.

Il est tout d'abord précisé que, sur les figures, les mêmes références désignent les mêmes éléments, quelle que soit la figure sur laquelle elles apparaissent et quelle que soit la forme de représentation de ces éléments.It is first of all specified that, in the figures, the same references designate the same elements, whatever the figure on which they appear and whatever the form of representation of these elements.

La présente invention concerne un système pour positionner un corps 10 dans un tube creux cylindrique 20 défini selon un axe longitudinal 22, lorsque ce positionnement doit être effectué à partir d'une extrémité donnée du tube, extrémité qui sera définie dans la présente description par "extrémité proximale 24".The present invention relates to a system for positioning a body 10 in a cylindrical hollow tube 20 defined along a longitudinal axis 22, when this positioning must be made from a given end of the tube, end to be defined in the present description by " proximal end 24 ".

Le système selon l'invention comporte, par référence aux figures 1 à 3 annexées, une gorge 30 réalisée dans la paroi intérieure 31 du tube 20 définie sur un arc de cercle d'angle au centre non nul jusqu'à une valeur préférentielle 360 degrés. Dans ce dernier cas, la gorge 30 est de forme annulaire sur tout le pourtour de la paroi intérieure du tube, comme représenté sur les figures 2 et 3, présentant l'avantage explicité ci-après.The system according to the invention comprises, with reference to Figures 1 to 3 appended, a groove 30 formed in the inner wall 31 of the tube 20 defined on an arc of angle circle at the non-zero center to a preferred value 360 degrees. In the latter case, the groove 30 is of annular shape all around the inner wall of the tube, as shown in the drawings. figures 2 and 3 , having the advantage explained below.

Cette gorge est réalisée dans la paroi intérieure 31 du tube et présente une forme définie par une première surface sensiblement tronconique 32 dont les petite 33 et grande 34 bases sont respectivement définies dans deux plans sensiblement perpendiculaires à l'axe longitudinal 22 du tube, la petite base 33 étant confondue avec la section transversale intérieure du tube et située entre l'extrémité proximale 24 du tube et la grande base 34 de la première surface tronconique, et par une surface annulaire 35 définie dans le plan de la grande base 34 de la première surface tronconique 32, cette surface annulaire étant bordée, sur son bord extérieur, par la première surface tronconique 32 et, sur son bord intérieur, par la paroi intérieure 31 du tube.This groove is made in the inner wall 31 of the tube and has a shape defined by a first substantially frustoconical surface 32 whose small 33 and large 34 bases are respectively defined in two planes substantially perpendicular to the longitudinal axis 22 of the tube, the small base 33 being merged with the cross section inside the tube and located between the proximal end 24 of the tube and the large base 34 of the first frustoconical surface, and by an annular surface 35 defined in the plane of the large base 34 of the first frustoconical surface 32, this annular surface being bordered on its outer edge by the first frustoconical surface 32 and, on its inner edge, by the inner wall 31 of the tube.

Si le tube est cylindrique de révolution, la première surface tronconique 32 sera aussi de révolution et sa petite base 33 sera un cercle de même diamètre que la paroi intérieure 31 du tube.If the tube is cylindrical of revolution, the first frustoconical surface 32 will also be of revolution and its small base 33 will be a circle of the same diameter as the inner wall 31 of the tube.

Sont aussi prévus un support 40, ce support étant agencé pour être apte à se translater dans le tube 20 suivant l'axe longitudinal 22, par exemple par coulissement, et des moyens 106 pour monter en coopération entre eux le corps 10 et le support 40. Ces moyens 106 peuvent être de tous types. Par exemple, dans le cas où le support 40 est séparé du corps 10, ces moyens 106 peuvent être constitués d'une patte ou analogue reliant le support et le corps. Mais il est aussi possible que le support et le corps soient réalisés d'une seule pièce, par exemple que le support 40 constitue une enveloppe ou analogue du corps 10.A support 40 is also provided, this support being arranged to be able to translate in the tube 20 along the longitudinal axis 22, for example by sliding, and means 106 for mounting the body 10 and the support 40 in cooperation with each other. These means 106 may be of any type. For example, in the case where the support 40 is separated from the body 10, these means 106 may consist of a tab or the like connecting the support and the body. But it is also possible that the support and the body are made in one piece, for example that the support 40 constitutes an envelope or the like of the body 10.

Le système comporte en outre un logement cylindrique ouvert 41 réalisé dans le support 40 en débouchant en regard de la paroi intérieure 31 du tube creux et défini selon un axe 42 sensiblement perpendiculaire à l'axe longitudinal 22 quand le support 40 est en translation dans le tube 20, et au moins un premier ergot 50, figures 1 et 2, monté en translation dans ce logement 41 à l'encontre d'une force élastique, ce premier ergot étant apte à prendre toutes positions dans le logement entre deux positions extrêmes, une première position "rentrée", figures 1 et 2, et une seconde position "sortie", figure 3, définie de façon que son extrémité 52 tournée vers la paroi intérieure 31 du tube et apte à émerger du logement pénètre dans la gorge 30 sous l'action de la force élastique quand l'ergot arrive en regard de la gorge et glisse dans cette gorge 30 jusqu'à venir buter contre au moins une partie de la surface annulaire 35, cette seconde position étant une position stable et bloquant le déplacement du support 40 par rapport au tube 20. La position du support 40 est donc ainsi parfaitement définie par rapport au tube 20.The system further comprises an open cylindrical housing 41 made in the support 40 opening out facing the inner wall 31 of the hollow tube and defined along an axis 42 substantially perpendicular to the longitudinal axis 22 when the support 40 is in translation in the tube 20, and at least one first lug 50, Figures 1 and 2 , mounted in translation in this housing 41 against an elastic force, the first pin being adapted to take any position in the housing between two extreme positions, a first "retracted" position, Figures 1 and 2 , and a second "output" position, figure 3 , defined so that its end 52 facing the inner wall 31 of the tube and able to emerge from the housing enters the groove 30 under the action of the elastic force when the lug comes opposite the groove and slides into this groove 30 to abut against at least a portion of the annular surface 35, this second position being a stable position and blocking the displacement of the support 40 relative to the tube 20. The position of the support 40 is thus perfectly defined with respect to the tube 20.

Il est précisé que cette seconde position "sortie" est une position stable de l'ergot, tandis que la première position "rentrée" ne l'est pas, c'est-à-dire que, si l'ergot est amené dans sa première position sous l'action d'une force donnée, il ne demeure dans cette première position que si la force donnée est maintenue, et qu'il passe automatiquement dans sa seconde position et y reste de façon stable dès que la force donnée est annulée.It is specified that this second position "output" is a stable position of the lug, while the first position "retracted" is not, that is to say, if the lug is brought into its first position under the action of a given force, it remains in this first position only if the given force is maintained, and it automatically goes into its second position and remains stably as soon as the given force is canceled .

Selon une réalisation avantageuse et préférentielle pour obtenir une seconde position du support stable dans une direction transversale à l'axe longitudinal 22 du tube, la face 53 de l'extrémité 52 du premier ergot 50 qui est apte à émerger du logement présente sensiblement la forme d'une seconde surface tronconique 54 qui, de plus, est sensiblement complémentaire de la première surface tronconique 32 de façon que, lorsque l'ergot 50 plonge dans la gorge 30, ou la portion de gorge, la face 53 de son extrémité 52 et la paroi de fond 36 de la gorge soient parfaitement ou au moins sensiblement congruentes.According to an advantageous and preferred embodiment for obtaining a second position of the stable support in a direction transverse to the longitudinal axis 22 of the tube, the face 53 of the end 52 of the first lug 50 which is able to emerge from the housing has substantially the shape a second frustoconical surface 54 which, in addition, is substantially complementary to the first frustoconical surface 32 so that, when the lug 50 dips into the groove 30, or the groove portion, the face 53 of its end 52 and the bottom wall 36 of the groove are perfectly or at least substantially congruent.

De plus, selon une autre réalisation avantageuse, la hauteur de la seconde surface tronconique 54 prise suivant une direction sensiblement parallèle à l'axe longitudinal 22 est au plus égale à la hauteur de la première surface tronconique 32, de préférence inférieure.In addition, according to another advantageous embodiment, the height of the second frustoconical surface 54 taken in a direction substantially parallel to the longitudinal axis 22 is at most equal to the height of the first frustoconical surface 32, preferably lower.

De façon préférentielle, pour un meilleur équilibre fonctionnel du système, comme illustré sur la figure 3, le logement 41 traverse de part en part le support 40 et le système comporte alors un second ergot 150 monté en translation dans ce logement 41 à l'encontre d'une force élastique, dans le sens opposé par rapport au premier ergot 50, ce second ergot 150 étant apte, comme le premier 50, à prendre toutes positions dans le logement entre deux positions extrêmes, une première position "rentrée" et une seconde position "sortie" définie de façon que son extrémité tournée vers la paroi intérieure 31 du tube et apte à émerger du logement pénètre dans la gorge 30 sous l'action de la force élastique quand il arrive en regard de celle-ci, cette seconde position du second ergot étant aussi une position stable.Preferably, for a better functional balance of the system, as illustrated on the figure 3 , the housing 41 passes right through the support 40 and the system then comprises a second lug 150 mounted in translation in this housing 41 against an elastic force, in the opposite direction relative to the first lug 50, second lug 150 being adapted, as the first 50, to take any position in the housing between two extreme positions, a first "retracted" position and a second "output" position defined so that its end facing the inner wall 31 of the tube and able to emerge from the housing penetrates the groove 30 under the action of the elastic force when it comes opposite it, this second position of the second lug being also a stable position.

Comme illustré sur les trois figures, la force élastique agissant sur un ergot 50 est donnée avantageusement par un ressort 60 monté en compression dans le logement 41. Lorsque le système comporte deux ergots 50, 150, cette force élastique est donnée par un seul ressort 60 monté en compression dans le logement entre les deux ergots.As illustrated in the three figures, the elastic force acting on a lug 50 is advantageously given by a spring 60 mounted in compression in the housing 41. When the system comprises two lugs 50, 150, this elastic force is given by a single spring 60 mounted in compression in the housing between the two lugs.

Comme illustré sur la figure 3, dans un mode de réalisation possible, l'ensemble comportant les deux ergots 50, 150 et le ressort en compression 60 est monté dans le logement 41 au moyen d'un caisson 43 en deux parties accouplées au moyen d'une bague et reliées entre elles par des boulons 44, ces boulons 44 permettant aussi de fixer le caisson dans le support. De façon avantageuse, ces deux parties de caisson peuvent en outre constituer des butées pour définir la seconde position "sortie" respectivement des deux ergots 50, 150. Cette réalisation parmi d'autres possibles ne sera pas plus amplement décrite car elle est du domaine de l'homme du métier.As illustrated on the figure 3 , in one possible embodiment, the assembly comprising the two lugs 50, 150 and the compression spring 60 is mounted in the housing 41 by means of a box 43 in two parts coupled by means of a ring and connected between they by bolts 44, these bolts 44 also for fixing the box in the support. Advantageously, these two box portions may further constitute stops to define the second "output" position respectively of the two lugs 50, 150. This embodiment among other possible will not be more fully described because it is in the field of the skilled person.

La présente invention peut avoir des applications dans de nombreux domaines mais, de façon très avantageuse, elle trouve une application, figure 3, à la mesure d'un paramètre déterminé dans un milieu 100 dans lequel est réalisé un forage 102, comme un terrain, sol, sous-sol ou analogue. Le tube 20 est alors constitué d'un tube dit "lanterné" c'est-à-dire comportant des fentes longitudinales 104, le corps 10 est constitué d'une sonde apte à mesurer le paramètre souhaité et les moyens 106 pour monter en coopération entre eux la sonde et le support 40 sont agencés de façon que, lorsque l'ergot (ou les ergots) 50, 150 est positionné dans la gorge 30, la sonde 10 soit sensiblement en regard des fentes longitudinales 104.The present invention may have applications in many fields but, very advantageously, it finds an application, figure 3 to the extent of a determined parameter in a medium 100 in which a borehole 102 is made, such as a ground, soil, subsoil or the like. The tube 20 then consists of a so-called "lanterned" tube that is to say having longitudinal slots 104, the body 10 consists of a probe capable of measuring the desired parameter and the means 106 for mounting in cooperation between them the probe and the support 40 are arranged so that, when the lug (or lugs) 50, 150 is positioned in the groove 30, the probe 10 is substantially opposite the longitudinal slots 104.

Comme illustré sur la figure 3, de façon préférentielle et avantageuse sur le plan pratique, la sonde est située entre l'entrée proximale 24 du tube 20 et le support 40.As illustrated on the figure 3 in a preferred and practical manner, the probe is located between the proximal inlet 24 of the tube 20 and the support 40.

Une telle sonde est par exemple une sonde pressiométrique, perméamétrique, un géophone, une sonde pour mesurer la teneur en eau du terrain, la résistivité, la température, la pression interstitielle, la radioactivité, la densité, etc.Such a probe is for example a pressuremeter probe, permeametric, a geophone, a probe for measuring the water content of the ground, the resistivity, the temperature, the interstitial pressure, the radioactivity, the density, etc.

En outre, pour obtenir en bon fonctionnement du système dans ce dernier cas de réalisation, comme il sera explicité ci-après lors de la description du fonctionnement du système, la largeur de chaque ergot 50, 150 prise dans un premier plan sensiblement perpendiculaire à l'axe longitudinal 22 quand le support 40 est en translation dans le tube 20, est au moins égale à la largeur de la fente la plus large définie dans un second plan sensiblement parallèle au premier plan.In addition, to obtain the system in good working order in the latter embodiment, as will be explained below in the description of the operation of the system, the width of each lug 50, 150 taken in a first plane substantially perpendicular to the longitudinal axis 22 when the support 40 is in translation in the tube 20, is at least equal to the width of the widest slot defined in a second plane substantially parallel to the first plane.

Le système décrit ci-dessus et illustré sur les figures 1 à 3 fonctionne et s'utilise de la façon suivante plus particulièrement décrite dans le cas de la réalisation selon la figure 3, étant entendu que le fonctionnement du système selon les figures 1 et 2 se déduira sans aucune difficulté de la description du fonctionnement du système selon la figure 3.The system described above and illustrated on Figures 1 to 3 operates and is used in the following manner more particularly described in the case of the embodiment according to the figure 3 , it being understood that the operation of the system according to the Figures 1 and 2 will be deduced without any difficulty from the description of the operation of the system according to the figure 3 .

On suppose que l'on veuille positionner la sonde 10 en regard des fentes 104 dans le tube lanterné 20. Pour cela, on associe la sonde 10 avec le support 40 de façon que la distance entre cette sonde 10 et les ergots 50, 150 soit égale ou sensiblement égale à la distance séparant la grande base 34 de la première surface tronconique 32 et le plan passant sensiblement par le milieu des fentes.It is assumed that we want to position the probe 10 opposite the slots 104 in the lantern tube 20. For this, the probe 10 is associated with the support 40 so that the distance between this probe 10 and the lugs 50, 150 is equal to or substantially equal to the distance separating the large base 34 from the first frustoconical surface 32 and the plane passing substantially through the middle of the slots.

On suppose en plus que le tube lanterné est descendu dans le forage 102 de façon que les fentes 104 soient en regard de la portion de terrain dont on veut mesurer un paramètre au moyen de la sonde 10.It is further assumed that the lanterned tube is lowered into the borehole 102 so that the slots 104 are facing the portion of land whose parameter is to be measured by means of the probe 10.

L'équipage comprenant la sonde et le support associés l'un à l'autre est descendu, par gravitation ou par poussée, dans le tube à partir de son extrémité proximale 24, les deux ergots étant amenés dans leur première position rentrée dans le logement 41. Lors de la descente de l'équipage, les deux extrémités 52 respectivement des ergots 50, 150 viennent, sous l'action du ressort en compression 60, se plaquer contre la paroi intérieure 31 du tube 20.The crew comprising the probe and the support associated with each other is lowered, by gravitation or by pushing, into the tube from its proximal end 24, the two lugs being brought into their first position retracted into the housing 41. During the descent of the crew, the two ends 52 respectively of the lugs 50, 150 come, under the action of the compression spring 60, to press against the inner wall 31 of the tube 20.

L'équipage est ainsi descendu jusqu'à ce que les ergots arrivent en regard de la gorge annulaire 30 après être passés devant les fentes 104 sans y tomber puisque leur largeur est supérieure à celle des fentes. A cet instant, les ergots poussés par le ressort 60 pénètrent dans la gorge et y descendent jusqu'à ce qu'ils butent contre la surface annulaire 35 de la gorge 30, la face 53 de l'extrémité 52 de chaque ergot étant en outre généralement plaquée contre la paroi de fond 36 de la gorge définie par la première surface tronconique 32.The crew is thus lowered until the lugs arrive opposite the annular groove 30 after having passed in front of the slots 104 without falling there since their width is greater than that of the slots. At this moment, the lugs pushed by the spring 60 penetrate into the groove and descend there until they abut against the annular surface 35 of the 30, the face 53 of the end 52 of each lug being further generally pressed against the bottom wall 36 of the groove defined by the first frustoconical surface 32.

L'équipage est en butée et ne peut plus continuer sa descente dans le tube. L'ergot 50 (ou les ergots 50, 150) étant en butée contre au moins une partie de la surface annulaire 35, la position du support 40 est donc ainsi parfaitement définie par rapport au tube 20.The crew is in abutment and can not continue its descent into the tube. The lug 50 (or the lugs 50, 150) being in abutment against at least a portion of the annular surface 35, the position of the support 40 is thus perfectly defined with respect to the tube 20.

Etant donné la distance définie ci-avant entre la sonde 10 et les ergots 50, 150, la sonde se trouve bien en regard des fentes 104.Given the distance defined above between the probe 10 and the lugs 50, 150, the probe is well opposite the slots 104.

La mesure du paramètre recherché peut alors être effectuée au moyen de la sonde 10 à l'endroit voulu.The measurement of the desired parameter can then be performed by means of the probe 10 at the desired location.

Quand la mesure est effectuée, il est possible de retirer l'équipage sans enlever le tube 20 du forage 102. Pour cela, il suffit d'effectuer une traction sur l'équipage suivant une direction parallèle à l'axe longitudinal 22 du tube. Du fait de la pente de la paroi de fond 36 de la gorge et de la forme complémentaire de la face 53 de l'extrémité 52 de chaque ergot 50, 150 qui frotte sur cette paroi de fond 36, la force de traction engendre une force qui tend à rétracter les ergots dans le logement 41 et à les translater de leur seconde position "sortie" vers leur première position "rentrée". Ainsi, l'équipage peut être remonté jusqu'à l'extrémité proximale 24 du tube en ayant la même configuration qu'il avait lors de sa descente.When the measurement is made, it is possible to remove the crew without removing the tube 20 from the borehole 102. To do this, it is sufficient to pull the crew in a direction parallel to the longitudinal axis 22 of the tube. Due to the slope of the bottom wall 36 of the groove and the complementary shape of the face 53 of the end 52 of each lug 50, 150 which rubs against this bottom wall 36, the traction force generates a force which tends to retract the lugs in the housing 41 and to translate from their second "output" position to their first "retracted" position. Thus, the crew can be raised to the proximal end 24 of the tube having the same configuration as it had during its descent.
