Method for developing oil and gas fields using high-power laser radiation for more complete oil and gas extraction

摘要

A method of developing oil and gas fields includes creating a well by mechanically displacing rock material via a drilling device, increasing a well diameter by impacting the rock material via laser beams emitted from a central emitter, and reinforcing inner walls of the well by impacting wall material via laser beams emitted from a lateral emitter. A system includes a drilling device with a hollow lumen and a central drilling head, at least one fiber optic cable positioned within the lumen, a laser source coupled to a proximal end of the cable, a central emitter positioned inside the central drilling head and coupled to a distal end of the cable, at least one lateral emitter positioned on a side wall of the drilling device and coupled to the cable, and a controller coupled to the central and lateral emitters for controlling at least one laser beam characteristic.
