CUTTING ELEMENTS HAVING LATERALLY ELONGATED SHAPES FOR USE WITH EARTH-BORING TOOLS, EARTH-BORING TOOLS INCLUDING SUCH CUTTING ELEMENTS, AND RELATED METHODS

摘要

A cutting element for an earth-boring tool includes a volume of superabrasive material on a substrate. The cutting element has an elongated shape in a lateral dimension parallel to a front cutting face of the cutting element, and has a maximum lateral width in a first direction parallel to the front cutting face of the cutting element and a maximum lateral length in a second perpendicular direction parallel to the front cutting face of the cutting element. The maximum lateral length is significantly greater than the maximum lateral width. An earth-boring tool includes one or more such cutting elements mounted to a body of the earth-boring tool. A method of forming such an earth-boring tool includes selecting at least one such cutting element and mounting the cutting element to a body of an earth-boring tool.

1. An earth-boring tool, comprising:
a body; and at least one cutting element mounted to the body, the at least one cutting element having an elongated shape in a lateral dimension parallel to a front cutting face of the at least one cutting element, the at least one cutting element having a maximum lateral width in a first direction parallel to the front cutting face of the at least one cutting element and a maximum lateral length in a second direction parallel to the front cutting face of the at least one cutting element, the second direction perpendicular to the first direction, the maximum lateral length being greater than the maximum lateral width; wherein the at least one cutting element is configured such that an area of a wear scar formed responsive to contact with a subterranean formation on the at least one cutting element is maintained at 25.8 mm2 or less at a linear wear distance of 2.54 mm or greater measured from an unworn cutting edge of the at least one cutting element in the second direction.
