casings

Casing is mainly used to protect the stability of hole wall, stop leakage and collapse, cut off aquifer and so on during drilling, so that the wireline core barrel can reach the designed depth smoothly. The casings are directly connected with male and female threads or with joints, and the casing shoe can be connected with the bottom end of the casing.
JINSHI casing pipes include three series which are W, WT and X drilling casing pipes, of which the W and WT series are directly connected and the X series are connected with joints, which all comply with international standards and are universally used in the world.
