Dans le monde du forage et de l'achèvement de puits, le terme "stack" peut faire référence à deux structures distinctes mais importantes : le stack de prévention des éruptions et le stack d'évacuation des vapeurs. Les deux jouent un rôle crucial pour assurer la sécurité et la protection de l'environnement.
1. Stack de prévention des éruptions :
2. Stack d'évacuation des vapeurs :
En conclusion :
Comprendre les différentes significations du terme "stack" dans le forage et l'achèvement de puits est crucial pour une communication efficace et des opérations sûres. Le stack de prévention des éruptions et le stack d'évacuation des vapeurs jouent tous deux un rôle vital pour assurer la sécurité et minimiser l'impact environnemental lors des activités de forage et d'achèvement de puits.
Instructions: Choose the best answer for each question.
1. What is the primary function of a blowout preventer (BOP) stack?

c) To prevent uncontrolled well flow (blowouts).
2. Which of the following is NOT a component of a typical BOP stack?
a) Annular preventer b) Blind shear rams c) Pipe rams d) Vapor disposal system
d) Vapor disposal system
3. What is the purpose of a vapor disposal stack?
a) To collect and store drilling fluids. b) To safely vent unwanted gases into the atmosphere. c) To provide a platform for wellhead equipment. d) To prevent the formation of gas hydrates.
b) To safely vent unwanted gases into the atmosphere.
4. What is the main reason for the height of a vapor disposal stack?
a) To increase the pressure of the gases being vented. b) To provide a visual landmark. c) To ensure proper dispersion of the gases. d) To collect rainwater for use in drilling operations.
c) To ensure proper dispersion of the gases.
5. Which of the following statements is TRUE about the "stack" in drilling and well completion?
a) The term "stack" only refers to the BOP stack. b) Both the BOP stack and the vapor disposal stack are crucial for safety and environmental protection. c) The vapor disposal stack is primarily used during drilling operations. d) The BOP stack is only used in emergency situations.
b) Both the BOP stack and the vapor disposal stack are crucial for safety and environmental protection.
Scenario: You are working on a drilling rig and notice a plume of gas escaping from the wellhead. The drilling supervisor asks you to take action to prevent a blowout.
Task: Describe the steps you would take to address the situation. Include the specific components of the BOP stack you would engage, and explain why.
Here's a possible solution:
It's important to remember that the specific steps taken will depend on the specific circumstances of the situation. However, the goal is to quickly and safely contain the gas flow and prevent a blowout.
