摘要： An earth boring bit has cutting elements arranged to avoid tracking. The bit has a bit body having a bit axis of rotation. First, second and third cones are rotatably mounted to the bit body, each of the cones having a plurality of rows of cutting elements including a heel row and an adjacent row. The heel row of the first cone has at least equal the number of cutting elements as the heel rows of the other cones. The adjacent row of the second cone has at least 90 percent as many cutting elements as the heel row of the first cone. The heel row of the third cone has a pitch that is in the range from 20-50% greater than the heel rows of the first cone.

摘要： A bit body is configured at its upper extent for connection into a drillstring. At least one fixed blade extends downwardly from the bit body, and has a radially outermost gage surface. A plurality of fixed cutting elements is secured to the fixed blade, preferably in a row at its rotationally leading edge. At least one bit leg is secured to the bit body and a rolling cutter is mounted for rotation on the bit leg. At least one stabilizer pad is disposed between the bit leg and the fixed blade, the stabilizer pad extending radially outward to substantially the gage surface. The radially outermost gage surface of each blade can extend axially downward parallel to the bit axis or angled (non-parallel), spirally or helically, relative to the bit axis.

摘要： A drill bit with a bit body having a central bore in communication with a plurality of nozzles for directing drilling fluid; a plurality of cutters defining a cutting face of the bit; and a passageway extending from the central bore toward the cutting face, such that excessive wear of the cutting face opens the passageway to allow the drilling fluid to flow therethrough, thereby reducing a surface pressure of the drilling fluid and indicating excessive wear of the bit. The passageway may extend to adjacent, or within one half inch or three inches of, the cutting face, such that excessive wear opens the passageway to the cutting face. In some cases, the passageway may actually extend through the cutting face with a plug inserted into the passageway at the cutting face to prevent the drilling fluid from exiting the passageway absent wear of the bit.
摘要翻译：一种钻头，其具有具有与用于引导钻井液体的多个喷嘴连通的中心孔的钻头; 限定所述钻头的切割面的多个切割器; 以及从中心孔朝向切割面延伸的通道，使得切割面的过度磨损打开通道以允许钻井流体流过其中，从而降低钻井液的表面压力并且指示钻头的过度磨损。通道可以延伸到切割面的相邻的或半英寸或三英寸以内，使得过度磨损将通道打开到切割面。在一些情况下，通道实际上可以通过插入到切割面处的通道中的塞子延伸穿过切割面，以防止钻井液离开通道而没有钻头的磨损。

摘要： An earth-boring bit has a body with three bit legs. A cone is rotatably mounted to each of the bit legs. Each of the cones has an outer row and an inner row of teeth machined on it. Each of the teeth has a rectangular root with inner, outer and lateral boundaries. A layer of hardfacing is applied to each tooth and on an exterior portion of each of the cones surrounding the inner, outer and lateral boundaries of each of the teeth. Conical surfaces between the inner and outer rows contain at least portions of the hardfacing.

摘要： An earth boring bit has at least one rotatable cone with a gage surface that engages a sidewall of a wellbore as the bit rotates. The gage surface has hardfacing bars spaced circumferentially apart from each other. A first group of the hardfacing bars extends from the inner edge of the gage surface to gage sides of the heel row cutting elements. A second group of the hardfacing bars extends from the inner edge of the gage surface to spaces between the heel row cutting elements, forming trimmer cutting elements. The hardfacing bars are made up of carbide particles in a metallic matrix.
