Le "câblage" est un processus crucial dans les opérations de forage et de complétion de puits, essentiel pour établir la connexion entre le derrick de forage et les outils de fond de trou. Ce processus consiste à enfiler soigneusement la ligne de forage (aussi connue sous le nom de "train de tiges") à travers les poulies du bloc couronne et du bloc voyageur, connectant finalement le tambour de levage à l'ancre de la ligne de forage.

Résumé :
Le câblage est une étape méticuleuse et importante dans les opérations de forage. Il établit la connexion essentielle entre le système de levage du derrick et les outils de fond de trou. En enfilant soigneusement la ligne de forage à travers les poulies, en s'assurant d'une tension adéquate et en effectuant les vérifications nécessaires, le derrick est préparé aux tâches exigeantes du forage, de la complétion du puits et, finalement, de l'extraction d'hydrocarbures précieux.
Instructions: Choose the best answer for each question.
1. What is the primary purpose of "stringing up" in drilling operations?
a) To connect the drilling rig to the downhole tools. b) To lubricate the drill string. c) To measure the depth of the well. d) To stabilize the drilling platform.
a) To connect the drilling rig to the downhole tools.
2. What is the drilling line typically made of?
a) Nylon rope b) Steel cable c) Aluminum wire d) Plastic tubing
b) Steel cable
3. Which of these is NOT a component involved in stringing up?
a) Hoisting drum b) Crown block c) Traveling block d) Mud pump
d) Mud pump
4. Why is tension applied to the drilling line during stringing up?
a) To prevent the line from breaking. b) To ensure the line is secure and prevents slippage. c) To increase the drilling speed. d) To improve the accuracy of depth measurement.
b) To ensure the line is secure and prevents slippage.
5. What is the final outcome of the stringing up process?
a) The rig is ready for drilling operations. b) The well is completed. c) The hydrocarbons are extracted. d) The drill string is lubricated.
a) The rig is ready for drilling operations.
Scenario: You are part of a drilling crew preparing for a new well. You are tasked with stringing up the drilling line.
Instructions: Describe the steps you would take to string up the drilling line, ensuring you follow the correct procedure. Include the necessary equipment and safety precautions.
Here's a possible solution for the exercise:
Steps for Stringing Up the Drilling Line:
Prepare the Drilling Line:
Threading the Sheaves:
Tensioning and Checking:
Finalization and Readiness:
Equipment: - Steel cable (drilling line) - Hoisting drum - Crown block - Traveling block - Sheaves - Drill-line anchor
Safety Precautions: - Wear appropriate personal protective equipment (PPE) like safety glasses, gloves, and hard hats. - Never work under a suspended load. - Use proper lifting techniques and ensure the line is securely fastened at both ends. - Communicate clearly with other crew members during the process. - Be aware of potential hazards like sharp edges and moving parts.
