摘要： A drill bit for drilling a borehole in an earthen formation may include a bit body having a bit axis and a direction of rotation about the bit axis; at least two blades extending azimuthally from the bit body; and a plurality of cutting elements disposed on the at least two blades; the plurality of cutting elements forming a cutting profile in a rotated profile view, each cutting element having a radial distance from the bit axis. At least one blade, at its formation facing surface, may include, between two radially adjacent cutting elements on the at least one blade, a raised depth of cut feature for each cutting element on the other of the at least two blades that are at radial distances from the bit axis intermediate the radial distances from the bit axis of the radially adjacent cutting elements on the at least one blade.
摘要翻译：用于在土层中钻孔的钻头可以包括具有钻头轴线和围绕钻头轴线的旋转方向的钻头体; 至少两个叶片从钻头体方位角延伸; 以及设置在所述至少两个叶片上的多个切割元件; 所述多个切割元件在旋转轮廓图中形成切割轮廓，每个切割元件具有距钻头轴线的径向距离。至少一个叶片在其面向表面的表面上可以包括在至少一个叶片上的两个径向相邻的切割元件之间，所述至少两个叶片中的另一个上的每个切割元件的凸起切割深度特征是径向的距离位轴的距离在距离至少一个叶片上的径向相邻切割元件的钻头轴线的径向距离之间。
