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.
