BW NW Casing Pipe Driiling Tools Reusable Effective Economical Foundation Drilling Tools
In wireline drilling tools project,larger sized of drill rods are been used as casing pipe,but for economical consideration,drill rods is easy to wear quickly,so casing pipe are recommend as an good choice,W series casing is reusable,effective and economical.
Casings are made of high quality geological pipes and they are connected tightly using pin and box thread,they also can match with casing shoes.
This kind of casing tube is able to stabilize the borehole. 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.
