Description
<B>La présente invention concerne un ensemble comporte</B> <B>une tige de pompe et un raccord fileté utilise pour la</B> commande <B>des pompes rotatives, telles</B> que <B>celles</B> qui <B>sont</B> <B>utilisées pour l'extraction et/ou la production fluides</B> <B>très</B> visqueux, <B>et de fluides ayant une concentration élevée</B> <B>en matières solides et un pourcentage modéré de</B> ,<B>tels</B> que <B>le pétrole, mais sans être limitée à cette application.</B> <B> The present invention relates to an assembly comprising a pump rod and a threaded connection used for the <B> control <B> of rotary pumps, such </ B> as <B> </ B> that <B> are <B> used for extraction and / or production fluids </ B> <B> very </ B> viscous, <B> and fluids having a concentration high in solids and a moderate percentage of <B> such as <B> oil, but not limited to this application. </ B>
<B>La tige de pompe</B> qui <B>existe actuellement est constituée</B> <B>d'une tige ayant un corps plein, raison pour laquelle on</B> <B>l'appelle "tige pleine de pompe" forgée à deux</B> extrémites. <B>Ces extrémités forgées ou têtes ont un</B> diamètre <B>nettement supérieur à celui du corps de la tige rapport</B> <B>des</B> diametres <B>de la tête et du corps est supérieur ou égal</B> à<B>118).</B> <B> The pump rod <B> that <B> currently exists is made up of a stem with a solid body, which is why we <B> call it </ b> pump full stem "forged at two </ b> extremites. <B> These forged ends or heads have a diameter <B> much greater than the body of the stem ratio <B> of the <B> diameter <B> of the head and body is greater than or equal to <B> 118). </ B>
<B>extrémités sont filetées à leur surface extérieure</B> <B>et constituent ce qu'on appelle des bouts mâles extré-</B> <B>mités mâles. Le raccord de deux tiges est réalisé à l'aide</B> <B>d'un</B> troisième <B>organe ou accouplement dont la surface</B> <B>interne est taraudée aux deux extrémités, et on l'appelle</B> <B>raccord femelle. Ces extrémités raccordent les organes</B> <B>filetés respectifs si bien que les organes sont raccordés</B> <B>grâce aux surfaces filetées et taraudées. Ce type de raccord</B> <B>actuellement utilisé est décrit dans la norme API 11H.</B> <B> ends are threaded on their outside surface </ B> <B> and constitute what are called male end ends. The connection of two rods is made by using a </ B> <B> third <B> organ or coupling whose inner surface is tapped at both ends, and it's called </ B> <B> female connector. These ends connect the respective threaded members so that the members are connected by threaded and threaded surfaces. This type of fitting currently used is described in API 11H. </ B>
<B>Ce type de tige pleine de pompe a été réalisé à l'ori-</B> <B>gine pour la mise en oeuvre du procédé traditionnel de</B> <B>pompage alternatif plutôt que pour les systèmes rotatifs de</B> <B>pompage dans</B> lesquels <B>il faut un moment de plus grande</B> <B>inertie polaire, à cause du type de contrainte appliquée. En</B> conséquence, <B>en présence d'une sollicitation de ce type de</B> <B>tige pleine par une contrainte de torsion lors de</B> <B>l'application d'un couple ou d'un moment de rotation, en</B> <B>combinaison ou non avec une contrainte de traction et/ou de</B> <B>flexion, le couple</B> qui <B>peut être transmis est limité. Une</B> <B>cause de rupture de ce type de tige classique est une</B> <B>rupture due à la</B> fatigue dans <B>la zone de jonction de la tête</B> <B>de la tige et de son corps, à cause de la différence de</B> <B>rigidité mécanique entre les deux parties, le corps de la</B> tige et la<B>tête de la tige.</B> <B>La présente invention a pour objet la réalisation d'un</B> ensemble <B>d'une tige de pompe et d'un raccord fileté, destiné</B> <B>la commande des pompes de type rotatif, capable de trans-</B> <B>mettre un couple supérieur à celui</B> que <B>peuvent transmettre</B> <B>les tiges pleines de pompe décrites dans la</B> norme <B>API 11B.</B> <B> This type of solid pump rod has been realized at the origin for the implementation of the traditional alternative pumping method rather than for rotary systems. of <p> pumping in </ B> which <B> requires a moment of greater polar <inertia>, because of the type of constraint applied. As a consequence, <B> in the presence of a solicitation of this type of </ B> <B> solid rod by a torsional stress when <B> <B> the application of a couple or a moment of rotation, in </ B> <B> combination or not with a tensile stress and / or </ b> <B> bending, the couple </ B> which <B> can be transmitted is limited. A cause of breakage of this type of conventional rod is a breakdown due to fatigue in the head junction area. </ B> <B> </ B> <BR> <BR> <BR> <BR> <B> of the stem and its body, because of the difference in </ B> <B> mechanical rigidity between the two parts, the body of the </ B> rod and the <B> head of the rod. The object of the present invention is to provide a pump rod assembly and a threaded connection for the control of Rotary-type pumps, capable of trans - </ B> <B> putting a torque higher than that <B> can transmit </ B> <B> the full pump rods described in the </ B> > standard <B> API 11B. </ B>
<B>En outre, l'invention a pour objet un raccord fileté</B> <B>pour tige creuse, différent de celui de la norme API 11B</B> <B>destiné aux tiges classiques, et</B> qui <B>peut être facilement</B> <B>assemblé.</B> <B> In addition, the invention relates to a threaded connection </ B> <B> for hollow rod, different from that of the standard API 11B </ B> <B> for conventional rods, and </ B > that <B> can be easily <B> assembled. </ B>
<B>L'invention concerne aussi la réalisation d'un ensemble</B> <B>d'un raccord de tige de pompe ayant peu tendance séparer</B> <B>les raccords qui relient les tiges</B> chaque <B>fois</B> que <B>se</B> <B>produit le phénomène de rotation en sens inverse des tiges.</B> <B>Ce phénomène se produit en fin d'utilisation et est dû à un</B> <B>accident ou est</B> provoqué <B>intentionnellement par l'activation</B> <B>de l'équipement de la pompe. A cause de l'énergie</B> emma- gasinée <B>dans la colonne des tiges en cours de fonction-</B> <B>nement, lors de la désactivation du fonctionnement de la</B> <B>pompe, la colonne tourne en sens inverse du sens dans</B> lequel <B>elle tournait avant la désactivation. La rotation de la</B> <B>colonne est inversement proportionnelle au</B> diamètre <B>de la</B> <B>tige et est proportionnelle au couple</B> appliqué <B>et à la</B> longueur <B>de la tige.</B> <B> The invention also relates to the realization of a set </ B> <B> of a pump rod connection having little tendency to separate </ B> <B> the connections which connect the rods </ B> every <B> time </ B> that <B> gets </ B> <B> produces the phenomenon of rotation in the opposite direction of the rods. </ B> <B> This phenomenon occurs at the end of use and is due to an accident or intentionally caused by the activation of the pump equipment. Due to the stored energy <B> in the column of running rods - </ B> <B> ment, when disabling the operation of the <B> <B> pump, the column rotates in the opposite direction in which <B> it was running before the deactivation. The rotation of the <B> <B> column is inversely proportional to the <B> diameter <B> of the <B> <B> rod and is proportional to the applied <B> <B> and to the </ B> length <B> of the rod. </ B>
<B>L'invention a aussi pour objet la mise à disposition</B> <B>d'un ensemble d'une tige et d'un raccord qui</B> permet <B>le</B> <B>passage d'outils (capteurs pour la gestion du puits) et/ou</B> <B>qui</B> permet <B>la circulation interne de fluides (injection de</B> <B>solvants et/ou d'inhibiteurs de corrosion).</B> <B> The object of the invention is also the provision of a set of rods and connectors which allows <B> the <B> <B> <B> > passage of tools (sensors for the management of the well) and / or <B> which </ B> allows <B> the internal circulation of fluids (injection of </ B> <B> solvents and / or corrosion inhibitors). </ B>
<B>L'invention concerne une tige de</B> forme <B>tubulaire ayant</B> <B>un corps creux,</B> qui <B>est taraudé à ses deux extrémités et</B> qui <B>est appelé "organe femelle". Elle comprend un embout ou</B> <B>organe ayant deux</B> extrémités <B>filetées, chaque extrémité</B> <B>étant filetée, étant appelée "organe</B> mâle" <B>et se raccordant</B> <B>à une extrémité femelle de la tige. L'accouplement entre les</B> <B>extrémités</B> mâle <B>et femelle est réalisé à l'aide des surfaces</B> <B>filetée et taraudée correspondantes. Le raccord fileté et le</B> <B>corps de la tige sont raccordés sans discontinuité de</B> diamètre, <B>alors</B> que <B>le rapport du diamètre du raccord au</B> <B>diamètre de la tige peut varier entre une valeur comprise</B> <B>entre 1, c'est-à-dire sans discontinuité des diamètres, et</B> <B>une valeur maximale de 1,5. Le fait</B> que <B>la valeur moyenne du</B> <B>diamètre extérieur sur toute la longueur de la colonne est</B> <B>supérieur celui qui est obtenu avec une tige possédant un</B> <B>raccord classique indique</B> que, <B>pour une</B> même longueur <B>de</B> colonne <B>et un</B> même <B>diamètre externe limité, la résistance</B> <B>la rotation en sens inverse est plus grande dans l'ensemble</B> <B>selon l'invention que dans la technique antérieure.</B> <B> The invention relates to a tubular <B> shaped rod having a hollow body, which is tapped at both ends and <b> which <B> is called "female organ". It includes a tip or <b> body with two <B> threaded ends, each end being threaded, being called "male member" <B> and connecting <B> to a female end of the rod. The coupling between the <B> <B> male <B> ends and the female is done using the corresponding threaded and tapped surfaces </ B> <B>. The threaded connection and the <B> rod body are connected without discontinuity of </ B> diameter, <B> then </ B> as the ratio of the diameter of the fitting to the </ B> <B> rod diameter can vary between a value </ B> <B> between 1, that is to say without discontinuity of diameters, and </ B> <B> a maximum value of 1.5 . The fact that <B> the average value of the <B> outer diameter over the entire length of the column is <B> higher than that obtained with a rod having a </ B> B> <B> classical fitting indicates <B> for <B> same <B> length of column <B> and <B> same <B> limited external diameter , the resistance <B> <B> the rotation in opposite direction is greater in the assembly </ B> <B> according to the invention than in the prior art. </ B>
<B>Les surfaces filetées ont un profil de filet qui assure</B> <B>un coincement diamétral sur la</B> longueur <B>du filet. Simulta-</B> <B>nément, les surfaces filetées et taraudées ont une forme</B> tronconique <B>qui facilite le montage.</B> <B> Threaded surfaces have a thread profile that ensures a diametric wedge on the <B> length <B> of the thread. Simulta - </ B> <B> The Threaded and Tapped Surfaces have a frustoconical <B> shape that makes mounting easier. </ B>
<B>Les dimensions de l'embout sont déterminées par</B> <B>l'obtention d'une distribution homogène des tensions sur</B> <B>toute la longueur de la partie filetée et dans le corps</B> <B>l'accouplement. I1 est ainsi possible d'obtenir un rapport</B> <B>de diamètre des extrémités filetées de l'embout et de son</B> <B>diamètre interne et un rapport du diamètre externe de</B> <B>l'embout et de son diamètre interne,</B> qui <B>sont caracté-</B> <B>ristiques du raccord, et un rapport supplémentaire entre le</B> <B>diamètre externe de l'embout et le diamètre des extrémités</B> <B>filetées de celui-ci.</B> <B> The dimensions of the tip are determined by </ B> <B> obtaining a homogeneous distribution of tensions over </ B> <B> the entire length of the threaded part and into the body </ B> <B> the coupling. It is thus possible to obtain a ratio </ B> <B> of diameter of the threaded ends of the tip and its <B> <B> internal diameter and a ratio of the outer diameter of </ B> <B > the tip and its internal diameter, which are characteristic of the fitting, and an additional ratio between the external diameter of the tip and the diameter of the threaded ends of it. </ b>
<B>Un congé des filets est défini de manière que la</B> <B>hauteur du congé sur l'embout soit supérieure ou égale à la</B> <B>hauteur du congé des extrémités taraudées.</B> <B> A net fillet is defined so that the fillet height on the end piece is greater than or equal to the tapped end fillet height. </ B> >
