Abstract

The invention relates to a laser-mechanical combined rock-breaking power drilling tool, which is mainly composed of a submersible motor, a laser beam pup joint, a laser head, a beam shaping mirror group, and a laser drill bit. The submersible motor is equipped with an inner channel and an outer channel, which respectively lead to gas / clear water and mud; the lower part of the submersible motor is provided with a rotor flange, which is connected to the laser beam nipple. The laser beam nipple is equipped with an inner channel and an outer channel, the outer channel transmits mud, and the inner channel transmits gas / clear water. Furthermore, the inner channel is equipped with a laser head and a beam shaping mirror group, and under the cooling and cleaning of gas / clean water, the laser is generated and shaped into a strip-shaped output. The laser drill bit is rotated by a submersible motor, and is equipped with a beam channel and a mud flow channel. The invention couples laser machinery with rock breaking, and injects gas / clear water to ensure that the laser effectively acts on the rock surface. Further, the gas / clear water cooperates with mud to clean the bottom of the well, which provides a method for laser rock breaking technology to be used in 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...
