Function Differences Between Drilling Casing And Tubing

Drilling casing and tubing are essential components in the oil and gas industry, each serving distinct functions in the drilling and production processes. Here are the main function differences between drilling casing and tubing.

 

Functions of Drilling Casing:

 Well Wall Protection:

When drilling, the instability of the formation structure can cause the well wall to collapse, leading to equipment stalling and drilling delays. The drilling casing shields the well wall from collapse, preserving its stability and preventing damage.

Well Pressure Control:

Drilling casing is indispensable in regulating well pressure, preventing the leakage of well water and gas. This function enhances safety for drilling personnel and operations.

 Wellbore Support:

The drilling casing supports the wellbore, stabilizing personnel and equipment in the event of a wellbore breakage or collapse during abnormal drilling conditions.

Cuttings Transport:

Drilling casing is used to transport drill cuttings, maintaining borehole clarity and facilitating efficient drilling operations.

 

Functions of Drilling Tubing:

 Oil Transport:

Drilling tubing is responsible for transporting oil, natural gas and other substances from the oil wells to storage tanks or processing plants, contributing to the processing and utilization of oil.

Oil Production Adjustment:

Operators can manipulate switches and valves on the oil pipe to adjust the collection speed and volume at the wellhead.

Prevention of Well Collapse:

Drilling tubing is used to prevent well collapse, enhancing the overall stability of the well.

Oil pipes protect the structure of the oil well from wear and corrosion, thereby ensuring its long-term production capacity. This protection is critical for sustaining consistent oil production over time.

In brief, drilling casing serves to safeguard the well wall, control well pressure, support the well structure, and convey drilling cuttings, among other functions. On the other hand, oil pipes are designed primarily for the transportation of oil, natural gas, water, and other substances, and as a means of regulating oil production and preventing oil well leakage, collapse, and damage.
