Stick-slip is a common phenomenon for mechanisms that involve motion with contact surfaces. Stick-slip often causes excessive and unwanted vibrations. For a drill string system, the stick-slip induced vibration often exists in the torsional direction. A drill string is a long slender structure. During "the stick phase," the bit comes to a standstill while the top of the drill string rotates with a constant rotary speed, thus increasing the torque in the drill string until the bit suddenly comes loose again, which is the "slip phase." It is reported that this type of "stick-slip" type of torsional vibration has a typical frequency of 0.05 to 0.5 Hz. To model, reduce, and even eliminate the stick-slip of the rock bit during drilling is receiving much attention in recent years, especially with the increasing use of the Polycrystalline diamond compact (PDC) bits which are more prone to the stick slip phenomena, causing high fluctuations of bit rotational speed and reduced life of bits. In the proposed invention, UH researchers in collaboration with Halliburton engineers developed a piezoceramic actuator based technique/device to eliminate the stick-slip in drilling. A prototype to study the effectiveness of the proposed device is being developed at Smart Materials and Structures Laboratory at University of Houston. The goal of this proposed invention is to eliminate stick-slip in drill string during hydrocarbon exploration.
