摘要： A method for estimating drilling parameters for drilling a borehole in the earth includes: drilling the borehole with a drill string having a mud motor and a drill bit; constructing a mathematical model of a system including the drill string, the mud motor, and a borehole geometry; calculating a mud motor lateral excitation force imposed on the drill string by the mud motor for one or more combinations of drill string rotational speed and mud motor rotational speed; calculating lateral motion of the drill string and a force imposed on the drill string at positions along the drill string for the one or more of combinations using the model and the excitation force; selecting a range of combinations of drill string rotational speed and mud motor rotational speed that result in the force imposed upon the drill string being less than a threshold value; and displaying the range of combinations.

摘要： A method of visualizing borehole system data includes obtaining first borehole system data, second borehole system data, third borehole system data, and fourth borehole system data corresponding to first, second, third, and fourth borehole system characteristics, respectively, of a first borehole system. The method includes binning the first, second, and third borehole system data to generate first binned borehole system data, second binned borehole system data, and third binned borehole system data, respectively. The method also includes generating a display of relationships among each of the first, second, and third binned borehole system data and the fourth borehole system data.

摘要： A method for presenting drilling information includes presenting a display including a graph having a first axis and a second axis. The first axis represents a rate of penetration (ROP) of a drill bit into a borehole and the second axis representing a mechanical specific energy (MSE) of a drilling system that includes the drill bit. The method also includes plotting time based or foot based data with a computing device for one or more drilling runs on the graph and overlaying the graph with lines of constant power.

摘要： An apparatus for reducing vibration includes a damping assembly configured to be fixedly attached to a downhole component. The downhole component is configured to rotate within a borehole in an earth formation, and the damping assembly has a damping frequency that is tuned relative to a selected natural vibration frequency of the rotating downhole component to reduce vibration due to component rotation.
