Abstract

The invention relates to a laser-machinery combined rock breaking power drilling tool which is mainly composed of a submersible motor, a laser beam nipple, a laser head, a beam shaping lens set and alaser drill bit. An inner channel and an outer channel are formed in the submersible motor, and gas / clear water and mud are introduced into the inner channel and the outer channel respectively; a rotor flange plate is arranged at the lower portion of the submersible motor and connected with the laser beam nipple; and the laser beam nipple is provided with an inner channel and an outer channel, theouter channel transmits the mud, and the inner channel transmits the gas / clear water; furthermore, the inner channel is provided with the laser head and the light beam shaping lens set, and under cooling and cleaning of the gas / clear water, laser is generated and shaped into a strip shape to be output; and the laser drill bit is driven by the submersible motor to rotate and is provided with a light beam channel and a mud flow channel. According to the laser-machinery combined rock breaking power drilling tool, the laser and machinery are coupled to jointly break rock, the gas / clear water is introduced to ensure that the laser effectively acts on the surface of the rock, further, the gas / clear water cooperates with the mud to jointly clean the bottom of a well, and a method is provided fora laser rock breaking technology for mud drilling.

Description

technical field [0001] The invention relates to a laser-mechanical combined rock-breaking power drilling tool, in particular to the field of oil drilling for deep, complex and difficult-to-drill formations. Background technique [0002] As a country with a large energy demand, the main battlefield of oil and gas exploration and development has gradually shifted to deep, complex and difficult-to-drill formations, and the difficulty of drilling has doubled. From the current point of view, conventional rotary drilling relies on high drilling pressure, high torque, and high speed. Increasing the ROP has been difficult to meet the needs of my country's green, safe and efficient rock breaking indicators and low-cost oil and gas development. [0003] Laser drilling technology is a new technology that has emerged in recent years. Studies have shown that using laser beams to directly act on rocks will cause damage and damage to rocks, the strength of rocks will be reduced, and the dri...
