Abstract

The invention relates to a drilling method for a laser drilling and mechanical grinding matching device, wherein an inner cavity of a double-cavity connecting chamber used for the laser drilling and mechanical grinding matching device is divided into a left chamber and a right chamber, a laser generator is installed in the right chamber, a laser transmitter is connected below the laser generator through a first connecting device, and a signal transmission system is installed in the inner cavity of the double-cavity connecting chamber; the laser generator is connected to the right end of the signal transmission system, and a pressure sensing device is connected to the left end of the signal transmission system; a drill rod and a first rotary disc are sequentially connected to the upper endof the double-cavity connecting chamber, a cable groove is formed in the inner wall of the drill rod, and a cable penetrates through the cable groove and is connected with the laser generator in the right chamber; and the laser transmitter and a second rotary disc are correspondingly connected to the lower end of the double-cavity connecting chamber through the first connecting device and a secondconnecting device, the second rotary disc is sequentially connected with a pressure disc group and the drill bit, and a water hole is formed in the center position of the drill bit. According to thedrilling method for the laser drilling and mechanical grinding matching device, drilling is carried out in a mode of laser cutting and mechanical grinding matching, so that the drilling speed is improved.

Description

Technical field: [0001] The invention relates to the field of drilling engineering, in particular to a laser drilling and mechanical grinding cooperation device and a drilling method. Background technique: [0002] Drilling is an important part of oil extraction. At present, many scientific researchers are constantly exploring new and effective drilling methods, including laser method, arc method, explosion method, electron beam method, electric spark method, etc., among which laser drilling technology includes drilling It has the advantages of fast speed and low drill bit wear, but this technology is still in the experimental research stage, and many aspects need innovation and in-depth research. For this new type of drilling method, a new type of laser drilling method and drill bit is urgently needed to meet the needs of drilling oil. mining needs. Invention content: [0003] The object of the present invention is to provide a kind of cooperating device for laser drilli...
