Laser rock fragmenting concept comes from the imagination utilizing laser energy fractured rock and drilling well that the people such as nineteen sixty-eight Massachusetts Institute of Technology Moavenzadeh F.McGarry F. J. and University of California Williamson R.B. propose in the 43rd SPE/AIME annual meeting in autumn.The result of Federal Aviation research light cutting rock test shows that the high-energy focusing radiation utilizing laser to send can cut out dark and thin joint-cutting on various solid rock, but the application of laser technology in oil drilling is at present few.
Summary of the invention
Object of the present invention for the deficiencies in the prior art, provide a kind of utilize laser energy directly act on rock stratum play cutting in advance, auxiliary rock, raising rate of penetration laser assisted break the fixing of rock toothdrill bit.
Present invention employs following technical scheme: a kind of laser assisted breaks the fixed teeth drill bit of rock, primarily of drill body, slurry channel, cutting teeth and wing composition, also comprise path channels and laser head.Path channels is arranged on drill body with different radii annular spread centered by bit-body axis, is provided with laser head in path channels.
In addition, path channels and slurry channel mutually isolated, path channels is opened at wing dorsal part, opens and is oriented to drill bit radial direction at the laser head of the path channels of wing dorsal part.
Laser assisted of the present invention breaks the fixed teeth drill bit of rock, have waterpower concurrently, machinery, laser three independently breaks rock mode, hydraulic drilling is to increase for the purpose of the water-horse power of shaft bottom, as super-pressure borehole pump, the superhigh pressure jetting, the pulsing jet utilizing various nozzle technology etc. that use shaft bottom booster; Mechanical rock breaking is exactly to increase well dynamic instrument for the purpose of drill bit mechanical energy energy, mainly contains the turbodrill, helicoid hydraulic motor and the electrodrill that increase the quiet moment of torsion of drill bit, has developed the axial impact drilling tool of the applicable rock bit of decades in addition.By installing one or more laser head on the drill bit rotated, the laser launched by laser instrument is radiated on rock by Optical Fiber Transmission, fragmentation, fusing, vaporization rock; make rock fragmentation become fritter, directly removed by drilling fluid, or change rock behavio(u)r; the particle breaking rock interior connects, and weakens rock, makes rock become loose; degree of porosity increases, and drillability improves, and avoids drill bit to contact with the direct of firm hard formation; reduce bit wear; protection drill bit, enhances productivity, and saves cost.
The invention has the beneficial effects as follows: the laser head on drill bit is more than or equal to one, the laser that the laser head being arranged on bit face middle sends is fixing irradiates rock stratum, being arranged on laser head on wing along with the increase of laser circuit radius increases gradually, along with the rotation of drill bit, the laser that laser head on wing sends irradiates strata movement, both acting in conjunction, in advance cutting rocks, add laser assisted on the basis of traditional machinery+hydraulic drilling and break rock.Like this; drill bit is while broken rock cuts; the laser that laser assisted breaks the multi beam smaller power density that rock fixed teeth drill bit utilizes laser head to send cuts in advance to rock, broken molten rock, changes the various characteristic of rock; destroy rock bulk strength; reduce drill bit and break rock difficulty, have auxiliary rock-breaking effect, can drill bit be protected; extend bit life, improve the high hard formation rate of penetration of drillability difference.
