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.
