摘要： An earth-boring bit has a high density row on one of its cones. Each cone has a nose area and a gage area with a heel row of teeth at the gage area. One of the cones has a farther intermediate row of teeth and another one of the cones has a closer intermediate row of teeth. The remaining cone has a high density row of teeth, which is located closer to the axis of rotation of the bit than the farther intermediate row and farther from the axis of rotation of the bit than the closer intermediate row. The high density row has a smaller pitch between crests of the teeth than the closer and farther intermediate rows. The smaller pitch provides more teeth in the high density row than in the closer intermediate row and the farther intermediate row.
摘要翻译：一个钻头在其一个锥体上具有高密度排。每个锥体都有一个鼻子区域和一个表面区域，在表面区域有一排跟随的牙齿。一个锥体具有更远的中间排的齿，另一个锥体具有更靠近的中间排的齿。剩余的锥体具有高密度排的齿，其位于比中间较远的位置更靠近钻头的旋转轴线，并且比钻头的旋转轴线更靠近中间行。高密度排在齿顶部之间的间距要小于越靠近和更远的中间行。更小的间距在高密度行中提供比在更靠近的中间行和更远的中间行中更多的齿。

摘要： An expandable reamer apparatus and methods for reaming a borehole are disclosed, including at least one laterally movable blade carried by a tubular body selectively positioned at an inward position and an expanded position. The at least one laterally movable blade, held inwardly by at least one blade-biasing element, may be forced outwardly by drilling fluid selectively allowed to communicate therewith or by at least one intermediate piston element. For example, an actuation sleeve may allow communication of drilling fluid with the at least one laterally movable blade in response to an actuation device being deployed within the drilling fluid. Alternatively, a chamber in communication with an intermediate piston element in structural communication with the at least one laterally movable blade may be pressurized by way of a movable sleeve, a downhole turbine, or a pump.

摘要： Hardfacing is applied on gage surfaces of bit blades, the leading and trailing edges of bit blades, and on carbide inserts. The gage surfaces contains natural diamonds, synthetic diamonds, thermally stable polycrystalline (TSP) diamonds and carbide inserts, and the hardfacing is applied over at least a portion of them. As primary cutters on the bit blades are worn down during drilling, the gage surfaces of the bit blades are also worn down. A hardfacing is applied to the worn gage surfaces of the bit blades, thereby allowing the drill bit to drill deeper and longer without requiring replacement.
