摘要： A method of drilling a borehole in an earth formation includes deploying a drilling assembly including a drill bit and a drill string, and performing a drilling operation according to one or more operational parameters to advance the drilling assembly through the formation, wherein performing the drilling operation includes rotating the drill bit and at least a portion of the drill string. The method also includes, during the advancing, monitoring a downhole condition, determining whether the downhole condition indicates at least one of a cuttings accumulation in the borehole and wear of a downhole component, and in response to the downhole condition indicating the cuttings accumulation or the wear, adjusting at least one operational parameter to induce or adjust an oscillating motion in the drill string, the oscillating motion causing at least one of a reduction in the cuttings accumulation and a reduction of wear of the downhole component.

摘要： A method for selecting drilling parameters for drilling a borehole penetrating the earth with a drill string. The method includes: measuring vibration-related amplitudes of the drill string during operation using one or more vibrations sensor to provide amplitude measurements; determining with a downhole processor one or more modal properties comprising one or more eigenfrequencies of the drill string using the amplitude measurements, the determination being made by including any excitation force in a white noise term of a model of the drillstring; and selecting drilling parameters that apply an excitation force at a frequency that avoids a selected range of frequencies that bound the one or more eigenfrequencies using the processor.

摘要： A method for determining wellbore trajectory includes determining survey parameters in the wellbore; measuring force parameter(s) in the wellbore; and correcting the survey parameters using the measured force parameter(s). The downhole measured force parameters may include forces associated with an operation of a steering device such as an internal reaction force, and /or a bending moment. In variants, the method may include measuring a wellbore temperature; measuring a wellbore parameter in addition to the temperature; and correcting a survey parameter using the measured parameter and the measured temperature. These methods may include correcting survey parameters using measured wellbore diameters. Also, a processor in the wellbore may be programmed to perform the correction while in the wellbore and / or control a steering device using measurements provided by a sensor for measuring internal reaction forces.

摘要： Method for estimating a steady state response of a drill string in a borehole includes calculating a first displacement of the drill string in a frequency domain for a first excitation force frequency and a number of multiples of this frequency using an equation of motion of the drill string. The equation of motion has a static force component, an excitation force component, and a non-linear force component with respect to at least one of deflection and a derivative of deflection of the drill string. The method further includes: transforming the first displacement from the frequency domain into a time domain; calculating a non-linear force in the time domain; calculating a frequency domain coefficient derived from the calculated nonlinear force in the time domain; and calculating a second displacement of the drill string in the frequency domain using the equation of motion and the frequency domain coefficient.
