Abstract
The invention relates to drilling engineering, in particular to impact drills for well drilling. The invention can be used while drilling inclined production and expendable wells for oil and gas, and drilling geological survey wells for solid minerals with large zenith angles. The impact drill, according to the invention, comprises a body that in the upper part includes a screw motor connected to the drill string; its mechanical rock-destruction unit is arranged as a matrix with the upper section rigidly connected to the body of the jet apparatus, and the lower one is porous. The drive of the screw motor is performed by means of washing liquid that circulates by the drill string. Due to use of the invention, decrease of power consumption for formation of load on mechanical rock-destruction unit of the device is achieved, first of all in the wells with intensive curvature. The rotary method for formation of peripheral zone of face, with use of ball fragments and products of destruction of rocks, makes it possible to eliminate termination of deepening because of parabolic form of the well bottom and large zenith angles.
