Shale gas horizontal well: Shale gas horizontal well is complicated and has serious wear on drill pipe, so EU type drill pipe should be used, because the outer layer of this drill pipe has been specially treated with wear resistance, and has a wear-resistant layer that can withstand more than 200 times of casing wear. Thereby improving the efficiency and safety of the overall operation, providing a strong guarantee for the efficient exploitation of shale gas.
Deepwater drilling: For deepwater drilling operations, IEU type drill pipe is the most suitable, because this drill pipe can withstand high pressure and can maintain safe sealing under an external pressure of 2,000psi. Since the deeper the water, the greater the water pressure, this feature is very important for deepwater drilling operations.
High sulfur oil field: For the exploitation of high sulfur oil fields, U-type drill pipe should be used and LC-95 material should be used. This strong combination can show extremely high corrosion resistance, and the sulfur stress corrosion index reaches the NACE MR0175 standard.
