Abstract

Au cours d'une phase initiale du cycle de traitement, on élève la pression au fond du puits, la pression étant limitée par la pression de fracturation hydraulique de la couche. On maintient la pression dans le fond du puits suffisamment longtemps pour déterminer une courbe piézométrique, la période appropriée étant déterminée par la stabilisation du débit. Après une remise en pression, la pression au fond du puits est rapidement amenée au-dessous de la pression de la formation par ouverture de l'espace annulaire et utilisation d'une pompe à jet (4). A mesure que la pression au fond du puits chute au-dessous de la pression de la formation, on utilise un générateur hydrodynamique (7) afin de créer des vibrations, ce qui se traduit par le mouvement par vibration du collecteur de plus de 0,1 fois le diamètre moyen des canaux des pores, ainsi qu'une vibro-accélération supérieure à 0,1 fois l'accélération en chute libre. La transmission d'impulsions de pression du générateur (7) jusque dans le lit 'comme à travers du fluide' augmente à mesure que l'exploitation de la zone de fond de puits progresse, bien que la valeur de décompression chute graduellement, le rayon de la zone couverte par la décompression et le rayon de traitement augmentant simultanément. Le procédé de l'invention est recommandé pour l'ouverture et l'exploitation de puits, notamment des puits exploités dans des conditions difficiles, ainsi que des puits déviés. Le procédé est caractérisé par un dégré élevé d'efficacité dans l'exploitation de puits exploités dans des conditions difficiles, et par le fait qu'il facilite l'exploitation efficace de puits déviés.
