High Anti-collapse Casing
With the depth increasing of drilling, the geological conditions become much more complex. The casing is subjected to much higher external pressure. The collapse strength of common API standard casing has been difficult to meet the requirements of the oil and gas wells with high or abnormal formation pressure, such as rock salt layer, mudstone layer or high-pressure water injection wells.
Thus, Glory Tube develops a series of high collapse strength casing to meet the different market need.
Uses
Used for oil and gas wells with high or abnormal formation pressure, such as rock salt layer, mudstone layer and high-pressure water injection wells.
