A method and apparatus are disclosed for generating intense acoustic pulses by means of water hammer effect on the surface and conveying these pulses through the drill pipe and drill collars down to the drill bit. Intensity of the acoustic pulses is increased in the bit nozzles. Vigorous pulsing of the fluid exiting the bit nozzles results in better cleaning of the hole bottom and faster drilling. By adding a down hole telescopic tool with multiple pistons arranged in series acoustic pulses are converted into a strong mechanical vibration which increases the efficiency of the drill bit and the whole drilling process. Vibration of the drill string reduces the friction between the drill string and the hole resulting in lower torque requirements. By adding a multiple piston telescopic tool above the drill bit and one or few drill collars acoustic pulse is converted into a strong mechanical upward pulse which causes the bottom end of the drill string to vibrate. Rate of drilling is increased while torque required for the drilling process is reduced.
