Casing Pipe
Introduction of Casing Pipe
Casing pipe
Drilling the casing pipe inside the borehole while drilling a well can stabilize the borehole and protect underground rock formation. As an important part for borehole safety, the casing pipe features the following functions:
1.Avoiding collapse of wall well, isolating different stratum to prevent liquid convection, thus liquid and pressure of the stratum can be controlled in the well drilling process.
2.The Casing pipe can assist the surface well control equipment and downhole drilling rigs to achieve control and communications functions.
3.We are able to customize casing pipes with diversified sizes to meet different borehole diameters.
Features of Casing Pipe:
. Use optimized buttress thread so that the connecting strength can reach the strength of the pipe body.
. High seal reliability: this product has the multi-seal configuration.
. The joint tool has high capability to resist compression, bending and over-torque load with the reverse torque internal shoulder.
. Energy loss reduction: the air and liquid turbulence are reduced by the inner flat design.
