Description
- les courts-circuits électriques (environ 80%),
- l'usure mécanique,
- la rupture mécanique.
- L'exploitation du puits engendre nécessairement des variations de pression et de température, dus aux arrêts et aux changements de régimes, dans les zones où se trouvent les équipements de pompage, créant des cycles de sollicitations mécaniques dans les matériaux constitutifs.
- Les variations de pression provoquent aussi des migrations répétées de gaz au sein des isolants, qui tendent à dégrader leur structure et leur performance.
- La présence d'hydrocarbures, d'aromatiques, de gaz acides et autres provoque des attaques chimiques diverses sur les différentes barrières d'isolation mécanique ou électrique, contribuant à leur dégradation dans le temps.
- Les variations de courant électrique (notamment les arrêts et démarrages du moteur) traversant les conducteurs électriques engendrent par effet Joule des variations de température importantes qui accélèrent le vieillissement des isolants électriques.
- Les voltages élevés évoqués ci-dessus génèrent des champs de sollicitations importants sur tous les isolants.
La présente invention a pour objet une installation pour puits pétrolier qui permet de séparer la partie électrique des parties mécaniques d'un groupe électropompe immergé dans le puits, de placer la partie électrique dans une enceinte à l'abri des agressions extérieures provenant notamment des effluents du fond de puits, et de regrouper les parties mécaniques afin de faciliter leur retrait, et de renforcer sa pérennité.
- la figure 1 est une vue en coupe d'une installation pour puits pétrolier selon un premier aspect de l'invention ;
- la figure 2 est une vue en coupe d'une installation pour puits pétrolier selon un deuxième aspect de l'invention ; et
- la figure 2A est une vue en coupe, prise selon la ligne A-A de la figure 2.
Claims (6)
- Installation pour puits pétrolier s'étendant de la surface (14) vers une couche de roche pétrolifère (16) comprenant un tubage (20) disposé dans le puits et formant une voie d'écoulement vers la surface pour des hydrocarbures provenant de la couche de roche pétrolifère, un cuvelage (18) délimitant la paroi du puits, et un joint (24) disposé en fond de puits entre le tubage (20) et le cuvelage (18) de manière à former une chambre (26) isolée des hydrocarbures, l'installation comprenant de plus, dans le puits, une pompe (30, 48) et un moteur électrique (34, 46) destiné à actionner la pompe, le stator (40, 52) et le câble du moteur électrique (38) étant disposés dans la chambre (26), à l'extérieur du tubage (20), caractérisée en ce que la chambre (26) contient une substance diélectrique.
- Installation selon la revendication 1 caractérisée en ce que le tubage (20) est formé de matériau amagnétique sur au moins la longueur où le tubage traverse le moteur électrique (34, 46).
- Installation selon la revendication 1 ou 2 caractérisée en ce que le moteur électrique est du type linéaire (34).
- Installation selon la revendication 1 ou 2 caractérisée en ce que le moteur électrique est du type rotatif (46).
- Installation selon l'une des revendications 1 à 4 caractérisée en ce que la pompe (30, 48) est disposée en amont du moteur électrique (34, 46).
- Installation selon l'une des revendications 1 à 5 caractérisée en ce que la partie mobile du moteur électrique (34, 46) comporte une tête d'accrochage (44) destinée à permettre de remonter à la surface ladite partie mobile et la pompe (30, 48).
