Abstract

Cette invention concerne un système de tringlerie d'essai et d'ajustement, comprenant un dispositif de distribution d'eau (1) et un dispositif d'essai et d'ajustement (2) disposé dans le dispositif de distribution d'eau (1). Un manchon de rail de guidage (4), un aimant supérieur (6), un aimant inférieur (8) et un injecteur d'eau ajustable (10) sont disposés à l'intérieur dudit dispositif de distribution d'eau (1). Un interrupteur magnétique (17), un bloc de positionnement mécanique (25) et une griffe mécanique (38) sont disposés à l'intérieur du dispositif d'essai et d'ajustement (2). Ledit bloc de positionnement mécanique (25) est utilisé pour le positionnement en coopération avec une base de positionnement C (52) dans le dispositif d'essai et d'ajustement (2). La griffe mécanique (38) coopère avec l'injecteur d'eau ajustable (10), de telle façon que le degré d'ouverture de l'injecteur d'eau ajustable (10) peut être ajusté librement, ce qui permet de contrôler avec précision la quantité d'eau injectée. L'invention présente les avantages d'un fonctionnement simplifié, d'une faible charge de travail, d'une haute efficacité, d'une haute précision et d'économie en main d'œuvre et en temps de manière à améliorer l'efficacité des essais, à réduire le temps d'essai et à améliorer la précision des données provenant de l'essai. De cette manière la difficulté de l'injection d'eau stratifiée dans un champ de pétrole est réduite, l'efficacité de l'opération est améliorée et les coûts de production sont réduits.
