摘要： An earth boring system is provided with universal cutter means for boring in all types of formations. The cutter means is mounted on a drill bit body or cutterhead with said bit or cutterhead functioning to form a hole in the earth formations. At least two annular rows of major inserts are mounted in the cutter means. The major inserts project from the surface of the cutter means a substantial distance for forming circular kerfs in the earth formations being bored. An annular row of minor inserts are mounted in the cutter means between the two annular rows of major inserts. The minor inserts project from the surface of the cutter means a distance that is substantially less than the distance the major inserts project from the surface of the cutter means.

摘要： A drilling bit for drilling earthen material such as an oil well rotary cone drilling bit, which includes means for preventing foreign particles such as sand, rock cuttings, etc., from reaching the rotational bearings of the bit cones. This end result is principally achieved by means of a centrifugal slinger disc or wall which is positioned in external concentricity with the drill bit cone bearing, and operates to drive granular particles away from the bearings, thereby preventing such particles from reaching these bearing surfaces. The granular particles are driven by the slinger action through a series of apertures forming a channel running out to a peripheral region of the bit cones. A channel continuation is also provided for lubricating fluid, which many comprise ambient water or oil placed in chambers surrounding the bearings, this channel providing access for such lubricating fluid inwardly to the bit cone bearings. A ring member carrying a plurality of curved vanes, this ring member being externally concentric with the supporting shaft of the cone and located near the outer periphery of the bit cone, may also be employed to prevent larger foreign particles, such as cuttings, from entering into the region of said slinger.

摘要： A rotary drill system is disclosed wherein drill stems extending into a bore hole have secured to one end thereof a sub and drill bit. The sub includes guide rollers rotatably mounted thereon. The drill bit includes a plurality of drill cones rotatably secured thereto and incorporates a passageway extending through the stems and the sub into the bore hole through the bit for transporting air with a lubricant entrained therein. A separator is mounted in the passageway for separating air from the lubricant; the air is permitted to pass through the bit to the work area for cooling the bit and transporting materials loosened by the drill cones to the surface. The liquid lubricant entrained in the air and separated by the separator is directed to separate passageways in the bit to the bearings of the drill cones, and is directed to the guide rollers mounted on the sub.

摘要： Lubricant is circulated from a lubricant reservoir to the bearings of a rotary rock bit and back to the lubricant reservoir by a lubricant circulation system that is operated by movement of the cone cutter upon the bearing pin of the bit. A positive seal is positioned between the rolling cone cutter and the arm of the bit to maintain lubricant in the bearing area and to prevent fluid in the borehole from entering the bearing area. A lubricant reservoir is located in the bit body. A first passage connects the lubricant reservoir with the bearing area to channel lubricant from the lubricant reservoir to the bearing area. A second passage extends from the bearing area to the lubricant reservoir to allow lubricant to be channeled back to the lubricant reservoir. A check valve in at least one of said passages insures one-way flow of lubricant. Axial movement of the cone cutter on the bearing pin provides a pumping action to circulate lubricant from the lubricant reservoir through said first passage to the bearing area and from the bearing area through said second passage back to said lubricant reservoir.
摘要翻译：润滑剂通过润滑剂循环系统从润滑剂储存器循环到旋转岩石钻头的轴承并返回到润滑剂储存器，润滑剂循环系统通过锥形切割器在钻头的轴承销的运动而操作。滚动锥形切割机和钻头臂之间有一个正密封，以保持轴承区域的润滑剂，并防止钻孔中的流体进入轴承区域。润滑剂储存器位于钻头体内。第一通道将润滑剂储存器连接到轴承区域，以将润滑剂从润滑剂储存器引导到轴承区域。第二通道从轴承区域延伸到润滑剂储存器，以允许润滑剂被引导回到润滑剂储存器。至少一个所述通道中的止回阀确保润滑剂的单向流动。锥形切割器在轴承销上的轴向运动提供泵送动作，以将来自润滑剂储存器的润滑剂从所述第一通道循环到轴承区域，并且通过所述第二通道从轴承区域循环回到所述润滑剂储存器。

摘要： THE PARTICULAR EMBODIMENT DESCRIBED HEREIN AS ILLUSTRATIVE OF ONE FORM OF THE INVENTION UTILIZES A DRILL BIT HAVING A FLUID EXIT FOR PASSING DRILLING FLUIDS FROM THE INTERIOR OF THE DRILL PIPE TO THE EXTERIOR OF THE DRILL BIT. THE SURFACE SURROUNDING THE EXIT IS FORMED IN THE SHAPE OF A PARABOLA. EXPLOSIVE CAPSULES ARE PLACED IN THE DRILLING FLUID STREAM AND THEN MOVED WITH THE DRILING FLUID THROUGH THE DRILL STEM AND OUT THE OPENING IN THE BIT FOR IMPACT WITH THE FORMATION, WHEREUPON THE EXPLOSIVE CAPSULE IS DETONATED. PRIMARY ENERGY IN THE FORM OF A SHAPED JET CHARGE IS DIRECTED INTO THE FORMATION TO PENETRATE THE BOTTOM OF THE BOREHOLE AND CAUSE FRACTURING OF FORMATION MATERIALS. IN ADDITION, UPWARDLY DIRECTED ENERGY FROM THE SHAPED EXPLOSIVE CHARGE IS REFLECTED FROM THE PARABOLICLIKE SURFACE OF THE DRILL BIT TO PROVIDE A SECONDARY ENERGY SOURCE DIRECTED AGAINST THE FORMATION AT THE BOTTOM OF THE BOREHOLE.
