oil drilling machine is undoubtedly the key to the whole system, so their study conducted in three areas, namely the dynamic oil drilling machine design, reliability, design and nonlinear analysis of three aspects. This is the beginning of the 20th century combined 90 years of modern design of the oil derrick method of significant results.

Oilfield drilling rig is one of the key equipment of production, with the continuous improvement of production efficiency, on the drilling system are increasingly high requirements. oil drilling machine in the drilling process requires frequent lifting, drill, drill as heavy lifting, stability requirements, in place accurately, this is a rig control system general requirements.
