Passerelle : Naviguer en Terrain Élevé dans le Forage et l'Achèvement de Puits

Le terme "passerelle" dans les opérations de forage et d'achèvement de puits fait référence à une passerelle surélevée conçue pour fournir un accès et des déplacements sécurisés dans la zone de travail d'un derrick. Bien que le terme soit quelque peu générique, deux applications spécifiques se démarquent :

1. Zone de travail surélevée :

Cette passerelle, souvent appelée "passerelle à tuyaux", est située à côté de la porte en V et de la rampe sur un derrick de forage. Son objectif est de fournir une plateforme sécurisée et stable pour la manipulation et la pose de tuyaux avant qu'ils ne soient hissés jusqu'au plancher du derrick. Cette zone cruciale sert de zone de préparation pour les tuyaux, facilitant la manipulation des tuyaux de manière efficace et organisée pendant les opérations de forage.

Caractéristiques clés :

  • Emplacement : Adjacent à la porte en V et à la rampe.
  • Fonction : Maintenir et organiser les tuyaux avant de les hisser jusqu'au plancher du derrick.
  • Équipement : Cable (treuil à câble) ou palan pneumatique pour hisser les tuyaux jusqu'au derrick.

2. Toute passerelle surélevée :

Au-delà de la passerelle spécifique de manipulation des tuyaux, "passerelle" peut également être utilisé pour décrire toute passerelle surélevée sur un derrick de forage. Ces passerelles peuvent servir à diverses fonctions, notamment :

  • Accès aux équipements et aux plateformes : Fournir un accès sûr et pratique aux différents niveaux du derrick, tels que le derrick, les réservoirs de boue ou la salle de contrôle.
  • Maintenance des équipements : Offrir une plateforme pour l'inspection, la maintenance et la réparation des composants critiques du derrick.
  • Sécurité et visibilité : Améliorer la sécurité des travailleurs en fournissant des passerelles surélevées au lieu de grimper sur des échelles ou des échafaudages, et améliorer la visibilité pour les travailleurs.

Importance des passerelles :

Les passerelles jouent un rôle crucial dans les opérations de forage et d'achèvement de puits. Elles offrent :

  • Sécurité : Éliminer la nécessité de grimper sur des échelles ou des échafaudages, minimisant les risques de chutes et d'accidents.
  • Efficacité : Faciliter le bon déroulement et l'organisation du travail en fournissant un accès sûr et pratique à divers équipements et zones de travail.
  • Visibilité : Permettre aux travailleurs de voir clairement la zone de travail et de maintenir une conscience situationnelle.

Résumé :

Le terme "passerelle" désigne une passerelle surélevée essentielle aux opérations de forage et d'achèvement de puits. Qu'elle fournisse une zone de préparation sécurisée pour la manipulation des tuyaux ou qu'elle permette l'accès à des équipements et des plateformes critiques, les passerelles contribuent de manière significative à l'efficacité, à la sécurité et à la réussite globale de ces opérations.

Catwalk Quiz: Navigating the High Ground

Instructions: Choose the best answer for each question.

1. What is the primary function of the "pipe catwalk" on a drilling rig? (a) Providing access to the derrick floor. (b) Storing drilling mud. (c) Holding and arranging pipe before lifting. (d) Housing electrical equipment.

Answer

The correct answer is (c). The pipe catwalk is specifically designed to hold and arrange pipe before it is lifted to the derrick floor.

2. Which of the following is NOT a common function of elevated walkways (catwalks) on a drilling rig? (a) Providing access to equipment and platforms. (b) Maintaining equipment. (c) Storing drill bits. (d) Enhancing worker safety and visibility.

Answer

The correct answer is (c). Catwalks are not typically used for storing drill bits.

3. What is the primary safety benefit provided by catwalks? (a) Eliminating the need for ladders or scaffolding. (b) Preventing spills of drilling mud. (c) Providing a platform for tool storage. (d) Improving communication between crew members.

Answer

The correct answer is (a). Catwalks eliminate the need for climbing ladders or scaffolding, reducing the risk of falls and accidents.

4. What is the significance of catwalks in well completion operations? (a) They are used to transport drilling fluid to the wellhead. (b) They provide access for installing and maintaining well completion equipment. (c) They help to control the flow of natural gas from the well. (d) They are used to monitor the pressure of the reservoir.

Answer

The correct answer is (b). Catwalks provide access for installing and maintaining well completion equipment, which is crucial for controlling and managing the production from the well.

5. Which of the following is a common piece of equipment used on the pipe catwalk to lift pipe? (a) Crane (b) Forklift (c) Catline (cable hoist) (d) Drill pipe

Answer

The correct answer is (c). A catline (cable hoist) is commonly used to lift pipe from the pipe catwalk to the derrick floor.

Catwalk Exercise: Safety First

Scenario: You are the supervisor on a drilling rig, and a new crew member needs to access the mud tanks for a routine check. The mud tanks are located on a platform accessible via an elevated walkway (catwalk).

Task: 1. List three safety precautions you would give the new crew member before they access the mud tanks using the catwalk. 2. Explain why these precautions are important for ensuring the crew member's safety.

Exercise Correction

Here are some possible safety precautions:

  1. Wear appropriate personal protective equipment (PPE): This could include safety shoes, a hard hat, gloves, and a high-visibility vest. This protects the crew member from potential hazards on the catwalk, like tripping or falling objects.
  2. Be aware of your surroundings: The crew member should be mindful of any obstructions or potential hazards on the catwalk. They should also be aware of other workers in the area and maintain a safe distance.
  3. Use handrails and avoid distractions: The crew member should always use handrails for support while walking on the catwalk, and avoid distractions that could cause them to lose their balance.

These precautions are essential for ensuring the crew member's safety by:

  • Minimizing the risk of falls: By wearing appropriate PPE, being aware of their surroundings, and using handrails, the crew member reduces the chance of tripping, slipping, or falling from the catwalk.
  • Preventing collisions: By being aware of other workers in the area, the crew member can avoid potential collisions and maintain a safe working environment.
  • Ensuring clear communication: By avoiding distractions, the crew member can focus on their task and communicate effectively with other workers.

Books

  • Drilling Engineering: Principles and Practices: This comprehensive textbook by Robert E. Krueger covers various aspects of drilling operations, including rig design and safety. It may contain sections related to catwalk design and function.
  • Petroleum Engineering Handbook: This reference book by John C. Donaldson provides a wide range of information on oil and gas extraction. It could offer valuable insights into rig infrastructure and safety procedures, potentially including catwalk considerations.

Articles

  • Safety on Drilling Rigs: Look for articles focusing on safety aspects of drilling operations. Such articles may discuss the importance of catwalks in minimizing fall hazards and improving accessibility.
  • Rig Design and Construction: Articles related to drilling rig design and construction might delve into the design considerations and standards associated with catwalks.
  • Drilling Rig Equipment and Operations: Publications on specific drilling equipment and procedures may provide information on the usage and importance of catwalks in practical drilling scenarios.

Online Resources
