An optical sensor for pH is described using a cross-linked network of bisilanes to immobilize a pH sensitive chromophore to a surface potentially exposed to a high pressure, high temperature environment such as wellbore effluents at a downhole location.
La présente invention concerne un détecteur optique de pH qui utilise un réseau réticulé de bisilanes pour immobiliser un chromophore sensible au pH sur une surface potentiellement exposée à un environnement à pression élevée et à haute température tel que des effluents de forage à un endroit en fond de puits.
