Abstract
Description
La présente invention a pour objet un procédé d'extinction par obturation des puits de pétrole en feu. The present invention relates to an extinguishing process by sealing off burning oil wells.
Certains procédés d'extinction des puits par obturation, déjà connus sont fiables mais extremement longs à mettre en oeuvre, tel que le brevet de MR KERMIT G. ROWLEY déposé en date du 7.03.72 sous le n"3 647 000 qui concerne l'obturation d'un puits caractérisé en ce qu'il comporte l'introduction dans la tête de puits de plusieurs éléments sphériques servant de tampon lorsqu'ils viennent se coincer dans le cintrage prévu à cet effet. Certain methods of extinguishing wells by obturation, already known are reliable but extremely time-consuming to implement, such as the patent of MR KERMIT G. ROWLEY filed on 7.03.72 under the number 3 647 000 which relates to the obturation of a well characterized in that it comprises the introduction into the well head of several spherical elements serving as a buffer when they get stuck in the bending provided for this purpose.
Le cintrage ainsi que le système d'introduction d'éléments sphériques doivent être installés sur la tête des puits de façon définitive, ce qui entraine une charge au niveau du cintrage et par conséquent un débit moins important lors de l'utilisation du puits. The bending as well as the system for introducing spherical elements must be installed on the head of the wells definitively, which causes a load at the level of the bending and consequently a lower flow rate when the well is used.
De même que le brevet n" 3 926 256 du 16.12.75 qui lui, nécessite l'installation d'une vanne à pistons autour de la tête du puits et qui est mise en action lors de l'injection des éléments formant un bouchon étanche prisonnier des pistons de part et d'autre du conduit. As well as patent n ° 3 926 256 of 16.12.75 which requires the installation of a piston valve around the head of the well and which is activated during the injection of the elements forming a tight plug trapped in pistons on either side of the conduit.
Cette installation présente l'inconvénient d'être définitive, coûteuse à la fabrication et non justifiée sur tous les puits de pétrole, si bien, que sur certains puits la vanne à pistons immergée n'est d'aucune utilité si ce n'est que pour arreter la production. This installation has the disadvantage of being final, costly to manufacture and not justified on all oil wells, so that on some wells the submerged piston valve is of no use except that to stop production.
Le but de l'invention est de présenter un procédé simple et rapide à mettre en oeuvre sans installation préalable sur le puits. The object of the invention is to present a simple and rapid process to be implemented without prior installation on the well.
A cet effet, le procédé selon l'invention de puits de pétrole en feu se caractérise essentiellement par
- l'obtention d'une baisse de niveau de pétrole
sous pression dans le conduit de délivrance,
- par l'introduction dans le conduit de délivrance
d'au moins un ballon souple expansible et incom
bustible susceptible de développer par expansion
dans le conduit un diamètre supérieur à celui du
dit conduit,
- par le gonflage du ballon au moyen d'une manche
d'arrivée de fluide dont il est muni, ce qui
bloque le ballon et obture le conduit.To this end, the method according to the invention of burning oil wells is essentially characterized by
- obtaining a drop in oil level
under pressure in the delivery duct,
- by the introduction into the delivery pipe
at least one flexible expandable and incom
bustible likely to develop by expansion
in the duct a diameter greater than that of
says led,
- by inflating the balloon by means of a sleeve
fluid inlet with which it is provided, which
blocks the balloon and closes the conduit.
Selon une autre caractéristique de l'invention, la baisse de niveau est obtenue par une dérivation sous l'extrémité supérieure du conduit et le ballon est introduit dans une ouverture ménagée dans la paroi du conduit entre la dérivation et l'extrémité supérieure. According to another characteristic of the invention, the drop in level is obtained by a bypass under the upper end of the conduit and the balloon is introduced into an opening formed in the wall of the conduit between the bypass and the upper end.
Suivant encore une autre forme de réalisation un premier ballon lesté est introduit par le haut dans le conduit jusqu'à la nappe puis gonflé, un abaissement du niveau de pétrole est effectué par pompage depuis la tête du puits et un deuxième ballon est introduit dans la tête du puits et gonflé. According to yet another embodiment, a first ballasted balloon is introduced from the top into the conduit to the water table then inflated, a lowering of the oil level is carried out by pumping from the head of the well and a second balloon is introduced into the well head and swollen.
D'autres avantages et caractéristiques de l'invention apparaitront à la lecture de la description ci-après de formes de réalisation données à titre d'exemples non limitatifs et illustrées par les dessins joints dans lesquels
- les figures 1 à 5 représentent une première forme de mise en oeuvre du procédé objet de l'invention,
- les figures 6 à 9 représentent une autre forme de mise en oeuvre du procédé objet de l'invention.Other advantages and characteristics of the invention will appear on reading the following description of embodiments given by way of non-limiting examples and illustrated by the accompanying drawings in which
FIGS. 1 to 5 represent a first form of implementation of the method which is the subject of the invention,
- Figures 6 to 9 show another form of implementation of the method of the invention.
En figure 1 est représenté schématiquement un puits de pétrole en feu. In Figure 1 is shown schematically a burning oil well.
Le niveau du pétrole qui monte dans le conduit de délivrance est mentionné par la flèche F1 et se situe au niveau de l'orifice supérieur du conduit 1. The level of oil which rises in the delivery pipe is indicated by the arrow F1 and is located at the level of the upper orifice of pipe 1.
Selon l'invention, on provoque une baisse du niveau de pétrole pour éviter les débordements. On utilise à cet effet un pipeline de dérivation 2 par pompage à la base du puits. According to the invention, a drop in the oil level is caused to avoid overflows. For this purpose, a bypass pipeline 2 is used by pumping at the base of the well.
L'abaissement de niveau en F2 sera en valeur coordonnée avec le volume d'un ballon 3. The level reduction in F2 will be in value coordinated with the volume of a balloon 3.
On réalise alors une ouverture 4 entre le pipeline de dérivation et l'orifice supérieur du conduit 1. An opening 4 is then produced between the bypass pipeline and the upper orifice of the conduit 1.
Par ladite ouverture un ballon souple 3 est introduit dans le conduit. Ce ballon est introduit dégonflé et va par flottaison occuper le volume libre en tête du conduit. Through said opening a flexible balloon 3 is introduced into the conduit. This balloon is introduced deflated and will float occupy the free volume at the top of the duct.
Au moyen d'une manche à air raccordée à un compresseur 5 le ballon est alors gonflé. Ce ballon est susceptible d'une expansion lui permettant de développer un diamètre supérieur à celui du conduit dans lequel il se bloque en obturant ledit conduit 1, ce qui éteint l'incendie faute de combustible. By means of an air bag connected to a compressor 5 the balloon is then inflated. This balloon is capable of expansion allowing it to develop a diameter greater than that of the conduit in which it is blocked by closing said conduit 1, which puts out the fire for lack of fuel.
Avantageusement, le ballon sera réalisé en une matière non-combustible, par exemple, à base d'amiante ou de tout autre matériau anti-feu dont la paroi extérieure sera rugueuse et/ou abrasive pour obtenir un contact étroit et rugueux contre la paroi. Advantageously, the balloon will be made of a non-combustible material, for example, based on asbestos or any other fire-resistant material whose outer wall will be rough and / or abrasive to obtain a close and rough contact against the wall.
L'opération peut être achevée par projection sur l'orifice de la tête du puits de sable pour obtenir un colmatage ou de neige carbonique. The operation can be completed by projection on the orifice of the head of the sand well to obtain a blockage or dry ice.
Après arrêt de l'incendie la remise en service du puits se fera par fermeture du pipeline 2 de dérivation, par fermeture de l'ouverture 4 de passage du ballon 3 et par enlèvement de celui-ci. After stopping the fire, the well will be put back into service by closing the bypass pipeline 2, by closing the opening 4 for passage of the balloon 3 and by removing it.
On peut également concevoir qu' après abaissement du niveau de pétrole de F1 à F2, le ballon 3 soit introduit par le haut au moyen d'un hélicoptère. It is also conceivable that after lowering the oil level from F1 to F2, the balloon 3 is introduced from above by means of a helicopter.
Dans ce cas, le ballon 3 sera muni d'un lest pour faciliter sa mise en place dans le conduit. In this case, the balloon 3 will be provided with a ballast to facilitate its positioning in the conduit.
Aux figures 6 à 10 est représenté une autre forme de réaisation du procédé objet de l'invention. FIGS. 6 to 10 show another form of embodiment of the method which is the subject of the invention.
Comme représenté, un premier ballon 3 lesté est introduit jusqu'au fond du puits puis gonflé en sorte d'obturer le puits par le bas, ce qui supprime la pression dans le conduit. As shown, a first ballasted balloon 3 is introduced to the bottom of the well then inflated so as to close the well from below, which relieves the pressure in the conduit.
Avantageusement, la mise en place du ballon dans le conduit s'effectue au moyen d'une grue associée à un compresseur 5. Advantageously, the positioning of the balloon in the conduit is carried out by means of a crane associated with a compressor 5.
Il est alors possible par pompage au moyen d'une pompe 6 par le haut de provoquer une baisse de niveau du pétrole pour ménager la place d'un deuxième ballon 3A lesté introduit par une deuxième grue avec compresseur de glonflage en sorte que ce ballon vienne obturer l'orifice supérieur du conduit ce qui éteint l'incendie. It is then possible by pumping by means of a pump 6 from above to cause a drop in oil level to provide space for a second ballasted balloon 3A introduced by a second crane with inflation pump so that this balloon comes close the upper opening of the duct, which puts out the fire.
Le ballon peut être placé dans un tube rigide fixé à la grue et amené par mouvement descendant de la flêche de la grue ou du filin. The balloon can be placed in a rigid tube fixed to the crane and brought in by downward movement of the boom of the crane or the rope.
Cette forme de réalisation est notamment applicable dans le cas où la pression trop élevée dans le conduit 1 pourrait s'opposer à l'action du lest. This embodiment is particularly applicable in the case where the excessively high pressure in the duct 1 could oppose the action of the ballast.
Il va de soi que le procédé selon l'invention et le matériel de mise en oeuvre (ballon) peuvent être intégrés au montage sur tous les puits à titre préventif. It goes without saying that the method according to the invention and the implementation equipment (balloon) can be integrated into the assembly on all the wells as a preventive measure.
Le procédé selon l'invention est particulièrement simple et rapide à mettre en oeuvre. The method according to the invention is particularly simple and quick to implement.
