Abstract

L'invention concerne un appareil de contrôle du sable résistant à la contamination et un procédé destiné à empêcher la contamination de dispositifs de contrôle du sable. Plus particulièrement, cette invention consiste à placer des produits chimiques de traitement à action retard dans un canal d'écoulement communiquant avec le dispositif de contrôle du sable. Ces produits chimiques prennent la forme de capsules à action retard ou sont revêtus d'une surface du dispositif de contrôle du sable et peuvent contenir des inhibiteurs de tartre, des inhibiteurs de paraffine, des inhibiteurs d'asphaltène, des enzymes et analogues. Les produits chimiques de traitement empêchent et balayent la formation et l'accumulation de particules sur une surface de l'appareil de contrôle du sable.
