  4. The problem of torque increase and drill fracture during the process of deep well drilling was analyzed, and a safety protection and control technique was introduced, where a torque sensor was fixed between drilling bar and motor axis, while an electromagnetic clutch was fixed in the transmission chain of feed system

    摘要對深孔鉆削過程中出現扭矩增大及折斷鉆頭鉆桿問題進行了分析，介紹了一種鉆桿主軸與電機軸的連接中安裝扭矩傳感器，進給系統的傳動鏈中安裝電磁離合器的深孔鉆削安全保護與控制技術。
  5. Along with the progress of drilling technology, many new types of bha such as steering motor assembly, dropping assembly with eccentric bend sub, dropping assembly with flexible connection are developed based on common building, dropping and holding assemblies. for using these bha, a new mathematical model is put forward for 3d static analysis of these types of bha under small deflection. and its weighted residual solution is given. the mathematical model includes ( 1 ) differential equations ; ( 2 ) boundary conditions at drill bit, stabilizer, bend angle, diameter change, tangential point and borehole wall ; ( 3 ) lateral forces and deflection angles of bit. the software based upon this method runs well
