A system for slowly releasing an oil-soluble well treatment agent into a well or a subterranean formation includes a composite of the oil-soluble well treatment agent associated with a second component. The amount of the oil-soluble well treatment agent in the composite is from 20 to 35 weight percent and the average particle size of the oil-soluble well treatment agent in the composite is less than or equal to 1 micrometer. The composite may further contain a water-soluble well treatment agent. L'invention concerne un système permettant de libérer lentement un agent de traitement de puits oléo-soluble dans un puits ou une formation souterraine qui comprend un composite de l'agent de traitement de puits oléo-soluble associé à un second constituant. La quantité de l'agent de traitement de puits oléo-soluble dans le composite est comprise entre 20 et 35 pour cent en poids et la taille moyenne des particules de l'agent de traitement de puits oléo-soluble dans le composite est inférieure ou égale à 1 micromètre. Le composite peut en outre contenir un agent de traitement de puits hydrosoluble.
