Embodiment Construction
[0020] Below in conjunction with accompanying drawing, the present invention will be further described:
[0021] Such as figure 1 As shown, this laser drilling device includes a surface part and an underground part. The underground part is mainly a drilling device installed in the wellbore, and the surface part is a device for supplying power to the underground drilling device, providing high-pressure gas, and processing bottom lava or dust. . Such as figure 1 As shown, a casing head 8 is installed in the wellhead above the ground to keep the inside of the wellbore 1 closed so as to realize gas circulation. A casing is laid at the surface depth of the wellbore 1, and the casing is a conventional casing with a length of about 100-200m. The conduit 2 extends downward into the wellbore 1 and extends to the bottom of the wellbore 1. The conduit 2 is a coiled pipe or a drill pipe, or it can be a string of other materials with high temperature resistance and certain strength and ...
