US 7434632 B2Abstract
Various types of cutting elements and cutting structures may be formed on a cone assembly. Each cutting element will typically have a normal force axis extending from the cone assembly. The term “cutting element profile angle” may be defined as an angle formed by a cutting element's normal force axis and associated cone rotational axis. For some roller cone drill bits the cutting element profile angle for cutting elements located in associated gauge rows may be approximately ninety degrees (90�). For example see FIGS. 4A, B, C and D.
Cone assemblies 30 a, 30 b and 30 c may be rotatably attached to respective spindles 34 extending from support arms 32. Cone assembly 30 a, 30 b and 30 c include respective axis of rotation 36 (sometimes referred to as “cone rotational axis”). The axis of rotation of a cone assembly often corresponds with the longitudinal center line of an associated spindle. Cutting or drilling action associated with drill bit 20 occurs as cutter cone assemblies 30 a, 30 b and 30 c roll around the bottom of a wellbore. The diameter of the resulting wellbore corresponds approximately with the combined outside diameter or gauge diameter associated with gauge face 42 cutter cone assemblies 30 a, 30 b and 30 c. A plurality of compacts 40 may be disposed in gauge face 42 of each cone assemblies 30 a, 30 b and 30 c. Compacts 40 may be used to “trim” the inside diameter of a wellbore to prevent other portions of gauge face 42 and/or backface 146 from contacting the adjacent formation. A plurality of cutting elements 60 may also be disposed on the exterior of each cone assembly 30 a, 30 b and 30 c in accordance with teachings of the present invention.
