Advancements in Stainless Steel Materials for Drilling Operations

Domestic drilling tool materials in China have primarily consisted of alloy structural steel, with high-end stainless steel drilling materials long being monopolized by foreign companies. During drilling operations, stainless steel materials must withstand complex conditions including high temperatures, high pressures, wear, and corrosion, necessitating extremely high performance requirements. Moreover, drilling materials are delivered as full-length units, demanding strict requirements for overall mechanical properties, structural integrity, straightness, and surface quality.

The company has invested significant human, material, and financial resources in research and development of stainless steel materials for drilling. Through continuous technical research and experimentation, they have developed drilling stainless steel materials that are better suited to drilling conditions and possess excellent properties, including high strength, high toughness, good corrosion resistance, and wear resistance.

Notably, stainless steel material with specifications of Ø210mm×6000mm was airlifted to Germany for comprehensive dissection and inspection. It ultimately passed certification, making the company the only domestic enterprise to achieve certification for this material. The development of these drilling stainless steel materials has not only improved the efficiency and safety of drilling operations but also provided strong support for the development of the oil and gas industry.

The company’s investment and achievements in the research and development of drilling stainless steel materials have secured its important position in the oil and gas industry, making a positive contribution to advancing China’s oil and gas industry.
