Combined-Full interlocking kelly bar is also known as concave-convex Kai-type pressurizing kelly bar.
It is characterized by external keys which composed by three subcomponent keys, and each external key are composed of fabric by the convex and concave tine. Driving internal keys are also composed of three sub-component keys.and each internal keys are also distributed by the concave and convex tine. The internal keys and external keys with driving force can be formed lock anywhere and anytime. During the drilling process, the driving force head send pressure directly to drilling head. Currently, the transmission pressure of this drill pipe is the best formation and permafrost; every site of the drill pipe can be formed the pressure point in the course of drilling, avoiding the drill in a part of the pipe wall caused by the pipe-sticking, at the same time, the convex and concave tine distributed in the driving internal key and external key have a good meshing. the pressurized part contains multi-point pressure ,which makes the kelly bar more efficiently.
