The accuracy of representing the drill string and wellbore wall interaction process in a model directly affects the quality of simulation results for well construction using a drill string. This simulation is currently the primary method for justifying the choice of optimal operating parameters and placement of axial vibration generators along the drill string. Considering that the drag forces resisting drill string motion depend on numerous factors—including normal contact force, mechanical properties of the drill pipe and rock material, drilling fluid properties, contact zone geometry, relative motion kinematics, and other parameters with poorly understood interrelationships — and given the research subject, laboratory experiments under conditions closest to real operational ones are the only viable way to study the drill string and wellbore wall interaction. This work describes a laboratory test rig developed to study the dynamics of frictional interaction between a drill pipe tool joint and rock. The rig consists of a frame, a drive system providing reciprocating oscillatory motion to a mandrel holding the tool joint (located in a trough filled with drilling fluid), a lever mechanism (using a hydraulic system to press rock samples against the tool joint), and a control and data acquisition system from sensors. The presented laboratory rig enables the study of frictional interaction dynamics between a full-size, oscillating drill pipe tool joint and rock samples immersed in drilling fluid. It allows for varying the kinematics of the oscillatory motion, the force pressing the rock samples against the tool joint, and the temperature of the drilling fluid.
