Dans le monde de l'exploration pétrolière et gazière, l'expression "remettre la colonne de forage" fait référence à une manœuvre spécifique et cruciale dans les opérations de forage et de travaux de réparation. Cela implique de placer soigneusement des sections de colonne de forage et de tiges de forage en position verticale sur le côté de la table tournante, située dans le derrick ou le mât du derrick de forage. Ce processus est essentiel pour diverses raisons, principalement pour faciliter la manipulation efficace et sûre de la colonne de forage.
Comprendre l'importance de remettre la colonne de forage :
Le processus de remise de la colonne de forage :
Colonne de forage à terre : une manœuvre complémentaire
Alors que remettre la colonne de forage est principalement lié à la manipulation de la colonne de forage, "mettre la colonne de forage à terre" est une autre technique importante dans les opérations de forage. Mettre la colonne de forage à terre implique de placer les sections de colonne de forage horizontalement sur le sol du derrick, généralement dans une zone désignée appelée "rack à colonne de forage".
Voici en quoi mettre la colonne de forage à terre diffère de remettre la colonne de forage :
Conclusion :
Remettre la colonne de forage et mettre la colonne de forage à terre sont des techniques essentielles dans les opérations de forage et d'achèvement des puits. Remettre la colonne de forage garantit une manipulation efficace et sûre de la colonne de forage, permettant des opérations de forage fluides et ininterrompues. Mettre la colonne de forage à terre, d'autre part, offre une solution de stockage structurée et organisée pour les colonnes de forage inutilisées, optimisant l'espace et favorisant l'ordre sur le sol du derrick.
Instructions: Choose the best answer for each question.
1. What is the primary reason for setting back the pipe?
a) To increase the drilling speed. b) To store unused pipe. c) To facilitate safe and efficient handling of the drill string. d) To reduce the risk of pipe corrosion.
c) To facilitate safe and efficient handling of the drill string.
2. What is the position of the pipe when it is set back?
a) Horizontal, on the rig floor. b) Vertical, in the center of the rotary table. c) Vertical, to one side of the rotary table. d) Diagonal, resting against the derrick.
c) Vertical, to one side of the rotary table.
3. Which of these actions is NOT involved in setting back the pipe?
a) Disconnecting the stand from the drill string. b) Lifting the stand vertically. c) Lowering the stand into the designated location. d) Replacing the drill bit.
d) Replacing the drill bit.
4. How does setting back the pipe improve safety?
a) By preventing the pipe from falling into the wellbore. b) By making the pipe lighter and easier to handle. c) By reducing the risk of entanglement or accidents caused by the weight of the pipe. d) By increasing the visibility of the pipe during operations.
c) By reducing the risk of entanglement or accidents caused by the weight of the pipe.
5. Which of these maneuvers is complementary to setting back the pipe?
a) Tripping out the drill string. b) Laying down pipe. c) Rotating the drill string. d) Injecting drilling mud.
b) Laying down pipe.
Scenario: You are the driller on a drilling rig. You have just pulled a stand of drill pipe from the wellbore and are ready to set it back for inspection. The drill floor is crowded with equipment and personnel.
Task:
**Steps Involved in Setting Back the Pipe:** 1. **Communication:** Inform the crew about the intention to set back the pipe, ensuring everyone is aware of the operation and their roles. 2. **Clear the Area:** Direct personnel and equipment to a safe distance from the area where the stand will be set back. 3. **Disconnect the Stand:** Carefully disconnect the stand from the bottom of the drill string, using the proper tools and safety procedures. 4. **Hoisting:** Use the rig's hoisting system to lift the stand vertically, ensuring it is clear of the rig floor and any obstacles. 5. **Lateral Movement:** Maneuver the stand laterally to the desired position, ensuring it is clear of other equipment and personnel. 6. **Lowering:** Carefully lower the stand to the designated location, ensuring a stable and secure position. **Ensuring Safe and Efficient Handling:** * **Clear Communication:** Constant communication between the driller and the crew is essential to coordinate movements, avoiding accidents and ensuring efficiency. * **Proper Tool Usage:** Ensure all tools and equipment are in good working order and used according to safety guidelines. * **Rig Safety Rules:** Enforce all rig safety rules, including appropriate personal protective equipment (PPE) and designated work zones. * **Obstacle Awareness:** Maintain constant awareness of the surrounding environment, including equipment, personnel, and potential hazards. * **Double-Check:** After each step, double-check that the pipe is secured and positioned correctly.
