Abstract
Underbalanced drilling technology has been extended deeply into every corner of the industrial productions and processes. In particular, the technology has a wide range of applications in oil and gas industries for the product design, manufacturing and construction process. In this work, a new air injection connector system has been developed for underbalanced drilling. The system development includes five key issues: original design, manufacturing control, experimental method, on-spot drilling design, and field work point control. The air injection connector system plays an important role and can significantly reduce potential losses during the drilling process.
