Abstract
The utility model relates to a downhole laser auxiliary rock-breaking drilling rig in the field of drilling tools. The downhole laser auxiliary rock-breaking drilling rig comprises a drilling head and a drilling rod, wherein a nozzle and a slurry channel are arranged in the drilling head and the drilling rod respectively, the nozzle and the slurry channel are mutually communicated, one to five laser heads are arranged in a drilling head body on the periphery of the nozzle in a sealing mode, and an optical fiber channel corresponding to each laser head is formed in the drilling head body. The downhole laser auxiliary rock-breaking drilling rig has the advantages that the laser heads are directly arranged on the drilling head, when the drilling head breaks rocks and conducts cutting, lasers simultaneously conducts rock breaking on a rock layer in a melting mode, the characteristics of the rocks are changed, meanwhile, a certain initiative rock breaking effect is achieved, and the mechanical drilling rate of a high-hardness earth layer which is poor in drillability can be improved.
Description
Technical field
The utility model relates to the drilling tool field, the drilling tool of especially a kind of down-hole laser auxiliary rock.
Background technology
Replace traditional churn drilling from the rotary drilling of 20 beginnings of the century, since realizing that oil drilling is reformed for the first time, drilling mode there is no than great change always, only be by utilizing new material and improving the performance that design improves drill bit, drilling speed when boring chance solid rock stratum to improve, but the rotary drilling mode still is to rely on high the pressure of the drill, high moment of torsion, high rotating speed to increase rate of penetration.The rock breaking mechanism of laser drill is to utilize superlaser fragmentation, fusing and evaporation rock.Laser drill is undoubtedly the direction of following drilling well development, has incomparable advantage than conventional drilling, is expected to bring a revolution to drilling well.But laser drill still is in the laboratory test stage at present, drop into commercial applications, also has a lot of technology or other problem to need to solve.
A kind of and mechanical laser aided drilling technology and the equipment (US20100078414) that combines that creep into of U.S. natural gas technical study institute issue patent " LASER ASSISTANTED DRILLING " in 2010 proposition; U.S. Argonne breadboard " METHODS OF USING A LASER TO SPALL AND DRILL HOLES IN ROCKS " proposes a kind of method of utilizing laser to cut and holing and equipment (US7416258) on rock; " WELLBORE LASER OPERATIONS " provides a kind of method and the change system (US20100326659) of drilling well, completion well laser operations.
Before 2007, China has successively finished " research of laser rock breaking mechanism and perforating technology ", " the reservoir properties research of the broken rock of laser perforation " and " the chip removal mechanism and the temperature field characteristics research of the broken rock of laser ", studies show that: high energy laser beam penetrates the laboratory test speed of argillaceous sandstone and shale sample can be up to 105 ~ 115 m/h, after the effect of rock Stimulated Light, near the heat affected zone rock exists macroscopic cracking and grows phenomenon, its degree of porosity increases, and permeability improves about 4 times.Simultaneously, rock has the trend that becomes fragile, and its strength limit reduces, and modulus of elasticity reduces.After the effect of rock Stimulated Light, fine and close glazing layer appears near the rock surface the heat affected zone in addition, also has micro-crack simultaneously and produces.When laser energy injected with the form of rectangular pulse, the average temperature of hot spot active region increased, and its vaporization nucleus strengthens, and the rock amount that is evaporated increases.
But also be in blank as the drilling tool that laser is directly applied to drilling well.
Summary of the invention
The purpose of this utility model is existing laser technology and the effective combination of drilling technology, and a kind of drilling tool of down-hole laser auxiliary rock of the rate of penetration that improves high hard formation is provided.
The utility model has adopted following technical scheme:
The drilling tool of a kind of down-hole laser auxiliary rock, comprise drill bit, drilling rod, be respectively equipped with the nozzle and the slurry channel of mutual perforation in drill bit and the drilling rod, 1-5 laser head of encapsulation in the peripheral bit body of nozzle, the corresponding optical-fibre channel of offering in bit body with each laser head.
Such scheme further comprises: supply module and laser generation module are set in the annular space between drilling rod and slurry channel, and laser generation module is connected by optical fiber with laser head.
Be provided with in the annular space between drilling rod and slurry channel, the optical fiber in the optical-fibre channel is drawn drilling rod after connecting laser head, and is connected with supply module with ground laser generation module.
Supply module is connected by interface module with laser generation module, adopts optical fiber interface to be connected between laser generation module and the optical fiber.
The beneficial effects of the utility model are: laser head is directly installed on the drill bit, drill bit is in broken rock cutting, and laser melts brokenly rock to the rock stratum simultaneously, when changing rock behavio(u)r, certain active rock breaking efficiency is arranged, can improve the high hard formation rate of penetration of drillability difference.
Description of drawings
Fig. 1 is the combining structure schematic diagram of the drilling tool of two kinds of laser auxiliary rocks;
Mark among the figure: 1-supply module; 2-laser generation module; The 3-target drill; The 4-drilling rod; The 5-slurry channel; The 6-optical-fibre channel; The 7-interface module; The 8-optical fiber interface; 9-optical fiber; The 10-nozzle; The 11-laser head.Supply module 1 and laser generation module 2 are respectively in ground setting and the drilling rod two states are set among the figure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The drilling tool of down-hole laser auxiliary rock comprises supply module 1, laser generation module 2 and target drill 3 compositions, supply module 1 connects laser generation module 2, drilling rod 4 is equipped with optical-fibre channel 6 with target drill 3 inside, inside is equipped with optical fiber 9, and laser generation module 2 connects laser head 11 by optical fiber 9.
Referring to Fig. 1, supply module 1 is energy sources of laser auxiliary rock drill bit with laser generation module 2, can be arranged in ground (mark part in the upper right corner among Fig. 1), also can directly be installed in the downhole tool 4.Laser generation module 2 is as lasing light emitter, and its output links to each other with laser head 11 by optical fiber.When ground configuration supply module 1 and laser generation module 2, between laser head 11 and laser generation module 2, there is optical fiber 9 need pass the long path channels 6 of layout in the drilling rod 4, laser energy is delivered to the laser head of installing on the target drill 3 11.If supply module 1 is connected by interface module 7 and is installed on the down-hole with laser generation module 2 is in the drilling rod 4, laser energy is passed to the laser head 11 of installation on the target drill 3 via the optical fiber 9 of optical-fibre channel 6 inside.
