Abstract

In this report a model for drilling response of the so- called drag bits (or PDC bits) is presented. Forces acting on a single cutter are supposed to be known. Discrete and continuous cutters distribution over the bit surface are considered. Both lead to similar relations between the bit kinematics characteristics and the force factors acting on it. While the bit penetration rate into the rock is small, the force and the torque are shown to depend linearly on the ratio between the bit transitional and rotational velocities (the depth of cut per revolution). Particular cases of the bit shape are compared.
