The invention belongs to the field of
petroleum drilling, in particular to an underground
turbine power
laser drilling tool. The underground
turbine power
laser drilling tool comprises a power source outer
barrel, a
stator blade, a rotor blade, a
turbine shaft, sealing rings, a generator outer
barrel, a
stator, a rotor, a limit joint, a
current transformer, an
optical fiber laser, a combiner, an
optical fiber, a
drill bit body and a laser head. The
stator blade and the rotor blade are connected with the turbine shaft and of an up-down two-stage structure, two O-shaped sealing rings are respectively arranged above and below the generator outer
barrel, the stator and the rotor coact to produce
electric energy, the
current transformer is arranged at the lower part of the generator outer barrel, the
optical fiber laser is arranged at the lower part of the limit joint, and laser produced by the combiner is transported to the laser head at the bottom of the
drill bit body through the optical
fiber. The underground turbine power
laser drilling tool can provide a stable power supply for the optical
fiber laser, high-energy laser
transmission convergence is guaranteed, an existing drilling technology is not changed, laser and
drill bit mechanical combined efficient
rock breaking is realized, and
petroleum drilling speed is effectively increased.
