Taper Tap : La "Lance" dans les Opérations de Pêche Pétrolières et Gazières

L'industrie pétrolière et gazière est constamment confrontée au défi de récupérer des équipements perdus ou endommagés dans les puits. Ce processus, connu sous le nom de "pêche", nécessite des outils et des techniques spécialisés. Un de ces outils, le Taper Tap, joue un rôle crucial dans la récupération d'objets avec des filetages internes ("poissons") bloqués dans le puits.

Qu'est-ce qu'un Taper Tap ?

Un Taper Tap est essentiellement un dispositif de pêche ressemblant à une lance conçu pour s'engager avec les filetages internes d'un poisson. Il dispose d'un corps conique qui permet une insertion facile dans le puits, suivi d'une section filetée qui correspond aux filetages internes de l'équipement perdu.

Comment ça marche ?

Insertion : Le Taper Tap est descendu dans le puits jusqu'à ce qu'il atteigne le poisson.
Engagement : Le corps conique guide le Taper Tap vers les filetages internes du poisson.
Verrouillage : Une fois que la section filetée s'engage avec les filetages du poisson, le Taper Tap assure une prise ferme.
Récupération : Le Taper Tap est ensuite utilisé pour retirer le poisson du puits.

Caractéristiques clés :

Corps conique : Cela permet une insertion plus facile et évite d'endommager les parois du puits.
Section filetée : Spécialement conçue pour correspondre aux filetages internes du poisson cible.
Construction robuste : Fabriqué avec des matériaux haute résistance pour résister aux rigueurs des opérations dans les puits.

Applications :

Les Taper Taps sont couramment utilisés pour récupérer :

Tubage perdu ou endommagé : Lorsque le tubage se bloque ou se casse, un Taper Tap peut aider à le retirer.
Revêtement coincé : Dans les situations où le revêtement est coincé dans le puits, un Taper Tap peut être utilisé pour le récupérer.
Autres composants filetés : Tout objet avec des filetages internes qui s'est coincé dans le puits peut être ciblé par un Taper Tap.

Avantages :

Conception relativement simple : Ce qui le rend plus facile à utiliser et à entretenir.
Efficace pour récupérer une large gamme de poissons : La polyvalence du Taper Tap en fait un outil précieux dans les opérations de pêche.
Rentable : Par rapport à d'autres outils de pêche, les Taper Taps peuvent offrir une solution plus abordable.

Limitations :

Limitée aux poissons avec des filetages internes : Les Taper Taps ne peuvent pas être utilisés pour récupérer des poissons sans filetages.
Risque de dommages : Si le Taper Tap n'est pas correctement aligné, il peut endommager le poisson ou le puits.

Conclusion :

Le Taper Tap est un outil crucial dans l'arsenal de pêche pétrolière et gazière. Sa conception simple et son efficacité dans la récupération d'équipements filetés en font un atout précieux pour les opérations de puits. Bien qu'il ne s'agisse pas d'une solution universelle, le Taper Tap offre une méthode fiable et rentable pour faire face à des défis de pêche spécifiques.

Taper Tap Exercise

Scenario: A piece of tubing has become stuck in the wellbore. The tubing has internal threads. You are tasked with retrieving the tubing using a Taper Tap.

Task: 1. Describe the steps involved in retrieving the stuck tubing using a Taper Tap. 2. Explain why a Taper Tap is a suitable tool for this task. 3. Identify potential risks associated with using a Taper Tap in this scenario.

Exercice Correction

1. Steps involved in retrieving the stuck tubing: 1. **Lowering the Taper Tap:** The Taper Tap is carefully lowered into the wellbore until it reaches the stuck tubing. 2. **Engaging the Threads:** The tapered body guides the Taper Tap towards the internal threads of the tubing. Once the threaded section of the Taper Tap engages with the tubing's threads, a secure grip is established. 3. **Retrieving the Tubing:** The Taper Tap is then used to lift the tubing out of the wellbore. 2. Why a Taper Tap is suitable: * The Taper Tap is specifically designed to engage with internal threads, making it ideal for retrieving tubing. * Its tapered body allows for easy insertion into the wellbore, minimizing the risk of damaging the wellbore walls. 3. Potential Risks: * **Improper Alignment:** If the Taper Tap is not properly aligned with the tubing's threads, it could damage the tubing or the wellbore. * **Over-tightening:** Excessive force applied during retrieval can damage the Taper Tap or the tubing. * **Stuck Taper Tap:** In some cases, the Taper Tap itself might become stuck in the wellbore, requiring additional fishing operations.
