Qu'est-ce qu'un EVXT TM ?
Un EVXT TM est une structure sous-marine spécialisée conçue pour contrôler et gérer le flux de pétrole et de gaz du puits de production vers le pipeline de production. Il agit comme le centre névralgique de la gestion de l'ensemble du processus de production, notamment :
- Connexion au puits de production : L'EVXT TM se connecte au puits de production, assurant la connexion au puits producteur.
- Contrôle de débit : Il abrite diverses vannes et étranglements pour réguler et contrôler le débit de pétrole et de gaz.
- Collecteur : Il s'intègre au collecteur de production, permettant la connexion de plusieurs puits à un seul pipeline.
- Instrumentation : L'EVXT TM intègre divers capteurs et instruments pour surveiller la pression, le débit et d'autres paramètres critiques.
- Intégration du système de contrôle : Il s'interface avec le système de contrôle sous-marin, permettant une exploitation et une surveillance à distance du processus de production.
Avantages de l'EVXT TM :
Comparé aux arbres verticaux traditionnels, l'EVXT TM offre plusieurs avantages :

Applications de l'EVXT TM :
L'EVXT TM est particulièrement avantageux dans divers scénarios sous-marins :
- Production en eaux profondes : La technologie excelle dans les environnements en eaux profondes, où les fluctuations de pression et de température posent des défis importants.
- Puits haute pression/haute température (HPHT) : La construction robuste de l'EVXT TM est parfaitement adaptée pour gérer les conditions exigeantes des puits HPHT.
- Production multiphasique : L'EVXT TM peut gérer efficacement le flux de pétrole, de gaz et d'eau simultanément, maximisant la production de puits difficiles.
- Durée de vie du puits prolongée : Le contrôle de débit amélioré et la conception optimisée de l'EVXT TM contribuent à une durée de vie du puits plus longue et à une production soutenue.
Conclusion :
L'EVXT TM témoigne de l'innovation constante dans l'industrie pétrolière et gazière. Ses performances améliorées, sa rentabilité et ses caractéristiques de sécurité contribuent de manière significative à maximiser l'efficacité de la production et la rentabilité des opérations sous-marines. Cette technologie continue d'évoluer, promettant une efficacité et une durabilité encore plus grandes dans les futurs systèmes de production sous-marins.
