Pinces à tuyaux : La prise qui propulse le forage et l'achèvement des puits
Dans le monde du forage pétrolier et gazier, une prise solide est essentielle. C'est là qu'interviennent les pinces à tuyaux, qui constituent l'outil crucial pour manipuler et manipuler les tiges de forage, le tubage et les tubages. Du sol animé du derrick de forage à l'étape complexe de l'achèvement du puits, ces pinces spécialisées sont indispensables pour des opérations efficaces et sûres.
Que sont les pinces à tuyaux ?
Les pinces à tuyaux sont essentiellement des clés à douille robustes conçues pour saisir et faire tourner des tuyaux de grand diamètre. Elles sont construites en acier haute résistance et comportent des mâchoires spécialisées qui s'engagent solidement dans le tuyau sans endommager sa surface.
Types de pinces à tuyaux :
Il existe différents types de pinces à tuyaux, chacun étant adapté à des applications spécifiques :
- Pinces à chaîne : Ces pinces utilisent une chaîne pour s'enrouler autour du tuyau, offrant une prise puissante. Elles sont idéales pour manipuler des tuyaux de grand diamètre et peuvent être facilement ajustées pour s'adapter à différentes tailles.
- Pinces araignées : Celles-ci présentent plusieurs mâchoires qui s'engagent radialement dans le tuyau, offrant une excellente stabilité et une excellente puissance de maintien. Elles sont couramment utilisées pour faire tourner et soulever des tuyaux lourds.
- Pinces élévatrices : Ces pinces sont conçues pour soulever et abaisser les tuyaux, généralement utilisées conjointement avec un palan ou une grue. Elles ont une configuration de mâchoire spécialisée qui permet une fixation sécurisée au tuyau.
- Pinces à mâchoires fendues : Ces pinces ont des mâchoires réglables qui peuvent être ouvertes et fermées pour s'adapter à différentes tailles de tuyaux. Elles sont particulièrement utiles pour saisir des tuyaux irréguliers ou endommagés.
Utilisations dans le forage et l'achèvement des puits :
Les pinces à tuyaux sont essentielles tout au long du cycle de vie du forage et de l'achèvement des puits :
- Forage : Elles sont utilisées pour réaliser et défaire les connexions entre les sections de tige de forage, ainsi que pour faire tourner la colonne de forage pour forer le puits.
- Opérations de tubage : Pendant les opérations de tubage, les pinces sont utilisées pour réaliser et défaire les connexions entre les sections de tubage, garantissant un support sécurisé du puits.
- Opérations de tubage : Les pinces à tuyaux sont essentielles pour manipuler et installer les tubages de production, facilitant l'écoulement du pétrole et du gaz du réservoir.
- Achèvement des puits : Les pinces sont utilisées dans diverses opérations d'achèvement, telles que l'installation d'équipements de production, l'installation de garnitures et la réalisation d'autres interventions sur les puits.
Considérations de sécurité :
Une manipulation et un entretien appropriés des pinces à tuyaux sont essentiels pour des opérations sûres.
- Inspecter l'usure : Vérifier régulièrement les signes de dommages, tels que des mâchoires fissurées ou des dents usées.
- Utiliser la bonne taille : Assurez-vous toujours que les pinces sont dimensionnées correctement pour le diamètre du tuyau.
- Serrage approprié : Appliquer un couple suffisant pour garantir une prise sécurisée, mais éviter de trop serrer, ce qui pourrait endommager le tuyau.
- Utiliser des équipements de sécurité : Portez toujours des gants et des équipements de sécurité appropriés lorsque vous utilisez des pinces à tuyaux.
Conclusion :
Les pinces à tuyaux font partie intégrante du processus de forage et d'achèvement des puits. Leur conception robuste et leur polyvalence permettent une manipulation efficace et sûre des tuyaux de grand diamètre, garantissant le bon déroulement des opérations et maximisant la productivité dans l'industrie pétrolière et gazière. En comprenant les différents types et leurs applications, les opérateurs peuvent s'assurer que les bonnes pinces sont utilisées pour chaque tâche, favorisant la sécurité et l'efficacité tout au long du cycle de vie du puits.

Pipe Tongs Exercise
Scenario: You are working on a drilling rig and need to connect two sections of drill pipe. You have a set of chain tongs and a set of split-jaw tongs available.
Task: 1. Determine which type of tongs is most appropriate for this task and explain your reasoning. 2. List at least two safety considerations you should keep in mind when using the chosen tongs.
Exercice Correction
1. Chain tongs are the most appropriate for this task.
Chain tongs are designed for making and breaking connections between pipe sections, which is the primary function needed in this scenario. They are ideal for handling drill pipe, and their adjustable chain allows for a secure grip on different pipe sizes.
2. Safety Considerations:
a) Inspect the tongs for any damage or wear before use. This includes checking for cracks in the jaws, worn teeth, or loose chain links. Damaged tongs could lead to slippage or failure during operation.
b) Ensure the tongs are properly sized for the drill pipe. Using tongs that are too small may lead to slippage and potential injuries, while tongs that are too large may damage the pipe.

Techniques
Pipe Tongs: A Comprehensive Guide
Chapter 1: Techniques
This chapter details the various techniques employed when using pipe tongs, emphasizing safety and efficiency. Proper technique is crucial to prevent accidents and equipment damage.
Making and Breaking Connections:
- Chain Tongs: The chain should be wrapped evenly around the pipe, ensuring a secure grip before applying torque. The chain should be tightened gradually, avoiding sudden jerking motions. Breaking connections requires a controlled release of tension, ensuring the pipe is properly supported to prevent damage or accidents.
- Spider Tongs: The jaws should be carefully aligned and firmly engaged before applying torque. Even pressure on all jaws is critical for preventing slippage and pipe damage. Breaking connections often involves counter-rotating the tongs slightly to break the grip.
- Elevator Tongs: Proper alignment with the lifting mechanism is essential. Ensure the tongs are securely latched onto the pipe before lifting. Lowering should be done slowly and steadily to prevent dropping or damage to the pipe.
- Split-Jaw Tongs: Adjust the jaws to securely grip the pipe before applying torque. The jaws should be evenly tightened to avoid uneven pressure and pipe damage. Care must be taken to ensure the jaws are properly positioned before attempting to break a connection.
Torque Application:
- Manual Tongs: Requires proper body mechanics to avoid injury. Controlled, even pressure is key.
- Power Tongs: Requires understanding of the power tong's controls and safety features. Over-torquing should be avoided to prevent pipe damage.
