A flame jet lance having a rotatable drill bit for forming cross holes in the ground is disclosed. The lance has various fuel and oxidizer tanks disposed therein and a fuel feed system coupled to the tanks for pumping the fuel to the rotatable drill bit. An extension member is also disposed in the lance with one end thereof coupled to the feed system and with the rotatable drill bit coupled at the other end thereof. The extension member is movable in the lance such that as the drill bit burns its way through the earth, the extension member moves the bit outward to a position lateral from the lance. In this manner, oil, gas, and the like may travel through the cross hole thus formed into the initial well hole. In operating the flame jet lance of the present invention, the lance is lowered into the preexisting well hole a specific distance. The flame jet drill bit is ignited and extremely hot flames are forced out through a nozzle contained in the drill bit. Because the extension member is adapted to move the drill bit laterally with respect to the lance, cross holes are created orthogonal to the initial well hole in the ground. This permits oil, gas and the like which had previously been unable to be pumped out of the surface from the original well hole, to now flow into the original hole and thus be rendered removable. By the use of the flame jet lance of the present invention, improvements in oil and gas recovery are achieved.
A flame jet tool forming cross holes in the ground comprising an elongated tube-like member, a fuel system disposed within said tube-like member, and an extension member comprised of a series of interconnected link members and having a first and second end with said first end being coupled to a drill bit, and said second end being coupled to said fuel system, said extension member being movable from a position within said tube-like member to an extended position lateral to said tube-like member.
A flame jet tool for forming cross holes in the ground comprising:
In a drilling system for forming holes in the ground, a drilling rig, a flame jet lance coupled to said rig such that said lance can be raised and lowered, and an extension member comprised of a series of interconnected links, said links having guide members for guiding said links in said lance, said extension member disposed in said lance having a drill bit at one end thereof and being movable from an initial position within said lance to an extended position outside of and lateral to said lance.
A flame jet tool for forming cross holes in the ground comprising an elongated tube-like manner, a fuel system disposed within said tube-like member, and an extension member comprised of a series of interconnected link members and having a first and second end with said first end being coupled to a drill bit, containing a rotatable nozzle member, and said second end being coupled to said fuel system, said extension member being movable from a position within said tube-like member to an extended position lateral to said tube-like member.
In a drilling system for forming holes in the ground, a drilling rig, a flame jet lance coupled to said rig such that said lance can be raised and lowered, and an extension member disposed in said lance having a drill bit at one end thereof and being movable from an initial position within said lance to an extended position outside of and lateral to said lance, and wherein driving means for moving said extension member is coupled to said extension member in said lance.
In a drilling system for forming holes in the ground, a drilling rig, a flame jet lance coupled to said rig such that said lance can be raised and lowered, and an extension member disposed in said lance having a drill bit at one end thereof and being movable from an initial position within said lance to an extended position outside of and lateral to said lance, and wherein fuel tanks are disposed in said lance and are coupled to said drill bit by flexible tubing, said tubing traveling through a cavity in said extension member.
