Application of “Crust 1” 10k ultra-deep scientific drilling rig in Songliao Basin Drilling Project (CCSD-SKII)

This paper presents the earth science program SinoProbe in China, especially the deep continental scientific drilling equipment: “Crust 1” 10k ultra-deep scientific drilling rig and 4 indigenous key equipment: Topdrive system, Pipe handler, Hydraulic catwalk and Iron roughneck. These equipment can save auxiliary time, improve drilling efficiency and reduce labor intensity. Components and technical parameters were also introduced. “Crust 1” was deployed to drill through the Cretaceous continental strata of continental scientific drilling well: Songliao Basin Drilling Project (CCSD-SKII), which is the deepest scientific drilling program in China. Casing program was also introduced in this paper. Automated equipment performs a critical function in CCSD-SKII, the application can provide experience for furthermore scientific drilling program with designed well depth over 10,000 m in China.
