In the world of oil and gas exploration, the phrase "setting back the pipe" refers to a specific and crucial maneuver in drilling and workover operations. It involves carefully placing stands of drill pipe and drill collars in a vertical position to one side of the rotary table, located in the derrick or mast of the drilling rig. This process is essential for various reasons, primarily to facilitate efficient and safe handling of the drilling string.
Understanding the Importance of Setting Back the Pipe:
The Process of Setting Back the Pipe:
Lay Down Pipe: A Complementary Maneuver
While setting back the pipe is primarily related to handling the drill string, "laying down pipe" is another important technique in drilling operations. Laying down pipe involves placing stands of pipe horizontally on the rig floor, typically in a designated area called the "pipe rack."
Here's how laying down pipe differs from setting back the pipe:
Conclusion:
Both setting back the pipe and laying down pipe are vital techniques in drilling and well completion operations. Setting back the pipe ensures efficient and safe handling of the drill string, allowing for seamless and uninterrupted drilling operations. Laying down pipe, on the other hand, provides a structured and organized storage solution for unused pipe, optimizing space and promoting order on the rig floor.
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.
