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 drill bit with a bit body (11) having a central bore (101) in communication with a plurality of nozzles (109, 111) for directing drilling fluid; a plurality of cutters (31) defining a cutting face of the bit; and a passageway (109) extending from the central bore (101) toward the cutting face, such that excessive wear of the cutting face opens the passageway (109) 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 (109) 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 (111) inserted into the passageway (109) at the cutting face to prevent the drilling fluid from exiting the passageway absent wear of the bit.
摘要翻译：一种具有钻头体（11）的钻头，其具有与用于引导钻井液体的多个喷嘴（109,111）连通的中心孔（101）; 限定钻头的切割面的多个切割器（31）; 以及从中心孔（101）朝向切割面延伸的通道（109），使得切割面的过度磨损打开通道（109）以允许钻井流体流过其中，从而降低钻孔的表面压力流体并指示钻头过度磨损。通道可以（109）延伸到切割面的相邻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在切割面处插入通道（109）中的插头（111）延伸穿过切割面，以防止钻井液离开该通道而没有钻头的磨损。

摘要： An earth boring drill bit (11) designed for a specific performance, within a finished product tolerance, using components built to a looser manufacturing tolerance. The bit may be assembled by selecting a leg (17) from a plurality of pre -manufactured legs; selecting a bit body (13) from a plurality of pre -manufactured bit bodies, the bit body having a slot (123) for receiving the leg; placing the leg within the slot; and fixing the leg within the slot within the finished product tolerance by placing one or more shims (200) between the leg and the slot. The shims may be used to adjust an axial position, a radial position, and/or a circumferential position of the leg with respect to the slot. The leg and the bit body may be selected, or produced, to ensure the bit will not meet the specification, given the manufacturing tolerance, without the shims.
摘要翻译：一种用于特定性能的地镗钻头（11），在成品公差范围内，使用构建于更宽松制造公差的部件。可以通过从多个预制造腿部选择腿部（17）来组装该钻头; 从多个预制造的钻头体中选择钻头体（13），所述钻头体具有用于接收所述支腿的槽（123）; 将腿放在槽内; 并且通过将一个或多个垫片（200）放置在所述腿部和所述狭槽之间，将所述腿部在所述狭槽内固定在成品容限内。垫片可以用于调节腿部相对于狭槽的轴向位置，径向位置和/或圆周位置。可以选择或生产腿和钻头体，以确保在给定制造公差的情况下，钻头不符合规格，没有垫片。
