BW NW HW PW Casing Pipe Driiling Tools Different Material Grades Resist Chemical Erosion![]()
In geological exploration,application of casing pipe is very important.
This kind of casing tube is able to stabilize the borehole during the drilling process. It has two functions: first, it can help prevent the well walls from collapsing and control the formation fluids. Second, it enables both well control equipment and downhole equipment to achieve their functions more easily .
Besides, it suits a wide variety of well diameters with different material grades. It is resistant to chemical erosion, also can withstand various external forces, like collision, bursting, tensile strength, etc.
