Oil Drilling Seamless Steel Casing Pipes N80 Steel Grade For Normal Well Conditions

Oil casing pipe descriptions:

Casing seamless pipe is mainly used for supporting the wall of the well during and after the drilling to

ensure the drilling process and the normal operation of the entire well after completion. The oil casing

pipe is the lifeline for maintaining the operation of the oil well.

Once a well has been drilled, if it is to become a production well, the well must undergo completion.

While drilling a well cuts through the rock formations and allows drilling engineers to reach the

reservoir below, the raw sides of the well cannot support themselves. Similar to the bones of

your spine protecting the spinal cord, casing is tubing that is set inside the drilled well to protect

and support the wellstream.

The cost of casing is a major part of the overall well cost, so selection of casing size, grade, connectors,

and setting depth is a primary engineering and economic consideration.

1. Alloy steel grade N80
