Title (EN) INHIBITING SCALE DEPOSITION IN OILFIELD TUBULARS
(FR) INHIBITION DU DEPOT DE TARTRE DANS DES TUBULURES DE CHAMP DE PETROLE
Abstract: front page image
(EN)Method for preventing scale deposition in a fluid that includes water and ions that can produce scale precipitation and deposition flowing through a well and/or other oil field tubular comprising arranging a liquid whistle for producing acoustic waves in the fluid in the tubular, and allowing at least part of the fluid that flows through the tubular to pass through the liquid whistle to generate acoustic waves.
(FR)La présente invention concerne un procédé pour empêcher un dépôt de tartre dans un fluide, comprenant de l'eau et des ions qui peuvent produire une précipitation et un dépôt de tartre, qui circule à travers un puits et/ou une autre tubulure de champ de pétrole. Ce procédé consiste à monter dans la tubulure un sifflet liquide conçu pour produire des ondes acoustiques dans le fluide, puis à permettre à au moins une partie du fluide qui circule à travers la tubulure de passer à travers le sifflet liquide, afin de produire des ondes acoustiques.
