Drill pipe oil well casing pipe oilfield casing and Tubing
Tubing and casing are two important pipes in oil wells. Tubing is a transportation pipe, generally made of stainless steel, galvanized steel or plastic, which is used to transport oil and gas in the reservoir to the surface and support the weight of the drill bit and casing. Casing is a pipe installed during the drilling process to secure the borehole, strengthen the well wall, complete the oil and gas well cement, stabilize the formation and prevent the well wall from collapsing.

What is the difference between casing and tubing?
Casing and tubing are essential components in oil well operations, serving different purposes throughout the well's lifecycle. Here is a comparison to clarify their differences:
- Casing is installed during the drilling phase to protect and stabilize the wellbore. Tubing is installed for production, to transport oil or gas to the surface.
- Casing provides structural integrity and isolation. Tubing is primarily used for the movement of oil or gas.
- The installation timing and functionality of casing and tubing distinguish their roles in well operations.
(1) Reinforce the well wall to prevent formation collapse;
(2) Seal different tubing layers and water layers to achieve layered mining;
(3) It is convenient to implement fracturing, acidification and other measures and maintenance operations.
(4) Form an tubing flow channel and cooperate with the tubing pipe to achieve the purpose of tubing production.
