It is the down-hole high pressure injection drilling tool of power with the turbine that Chinese patent application CN00250432.4 discloses a kind of.It is provided with the gearbox of a raising centrifugal pump rotating speed, to increase the expulsion pressure of drilling fluid.Though this drilling tool can provide continuous high-pressure spray, its efficiency of breaking rock is not high, and serious wear.
Summary of the invention
In order to overcome the deficiency that existing drilling tool bit speed is low or the life-span is short, the utility model provides a kind of high pressure continuous flow to spray the combined-breaking rock drilling tool of broken rock, clear rock and the broken rock of drill bit, reaches the purpose that improves bit speed.
The technical scheme that its technical problem that solves the utility model adopts is: increased the high pressure continuous flow and spray broken rock, Qing Yan on the basis of conventional bit well drilling and rock crushing.
The beneficial effects of the utility model are to improve bit speed in drilling well.
